Release Notes for Cisco MGX 8850 (PXM1E/PXM45) and MGX 8830, Software Release 3.0.25


Contents

About Release 3.0.25

Release 3.0.25 is a software maintenance release for the MGX 8830 PNNI routing switch and for the MGX 8850 switch.

Locating Software Updates

For the MGX 8830 and the MGX 8850, software updates are located at Cisco Connection Online (CCO) at the following location:

http://www.cisco.com/kobayashi/sw-center/wan/wan-planner.shtml

Frame Discard Feature

New developments have occurred in the CLI for the Frame Discard feature in connection provisioning. Starting with releases 3.0.23 and 4.0.10, two types of frame discard became available. For a detailed explanation, see the addcon or cnfcon description in either the Cisco MGX 8830, MGX 8850 (PXM45 and PXM1E), and Cisco MGX 8950 Command Reference (Release 3 or 4) or the Cisco ATM Services (AXSM) Software Configuration Guide and Command Reference for MGX Switches (Release 3 or 4). Also see the Note in the Installation and Upgrade section of these release notes.

About Release 3.0.23

Release 3.0.23 is a software maintenance release for the MGX 8830 PNNI routing switch and for the MGX 8850 (PXM45) and MGX 8850 (PXM1E) switches.

About Release 3.0.20

Release 3.0.20 contains these new features:

SPVC Connection Statistics

AXSM-E OAM Enhancements

CLI Configurable Access

Controller Card Mastership Sanity Verification Enhancement

Serial Bus Path Fault Isolation Enhancement

Cell Bus Path Fault Isolation and Recovery Enhancement

SPVC Connection Statistics

SPVC connection statistics display the statistics generated for the originator node, and for an MPG node, it displays the statistics for the border nodes. It will show the number of SPVC connections that are successfully routed, number of connections that are failed, and the number of crankbacks initiated and received.

AXSM-E OAM Enhancements

The AXSM-E OAM enhancements consist of two changes. The first change modified the driver for the AXSM-E card to successfully pass high volume of OAM cells. The second change enhanced the OAM task to better share the node resources with the other cards in the node.

This feature is available only for the MGX 8850 switch with the PXM45 controller.

CLI Configurable Access

A new command, cnfcli, has been created to allow administrators to customize the CLI command access levels. An ASCII file with the command names and the corresponding new command access levels is created by an administrator. This file is FTP'ed to the node. This file contains commands for the whole node, irrespective of the card types (one file per system). Then cnfcli is invoked to parse and install the new command access levels.

Controller Card Mastership Sanity Verification

This feature provides checks to validate the hardware mastership states on the active and standby PXM cards. The scope of this enhancement in this release is to detect invalid mastership states, send a trap, and log more information. This feature does not provide any new auto-corrective action when a mastership problem is detected.

Serial Bus Path Fault Isolation

The MGX 8850 currently uses the serial bus for its data path transport. The switching ASICs and Humvee chips on the PXM and Switch Module cards are designed to detect data integrity and chip errors.

When an error is detected on the switching fabric path by either the Service Module cards, or the Switching Fabric card (e.g., PXM45, or XM60) and if the error count exceeds its error threshold, the error is reported to the PXM, and the PXM will take one or more of the following corrective actions:

shutdown the humvee/switch fabric link that is reporting errors

switch to a standby switching module

switch to a standby PXM module

reset the active switch module (SM)

Table 1 summarizes the enhancements made in this firmware release in isolation and recovery procedures:

Table 1 Enhancements to Isolation and Recovery Procedures 

Failure Detection

Isolation

Recovery

Humvee Errors on SM

Isolate local Humvee errors before reporting failure to the PXM. Speed up detection/isolation of Humvee SFRAME errors to be less than 10msec versus the current (2+ seconds).

Follow current recovery procedure when such an error is detected.

1) Shutdown the link that reported the errors

2) If all links going toward an SM card fails, move the SM slot to degraded mode, and if redundancy is available on that SM, switch the standby SM to be active.

3) If all links reported error on a card, leave the last failed link up.

Humvee Errors Reported on the PXM

Isolate local Humvee errors before reporting failure to the PXM. Speed up detection/isolation of Humvee SFRAME errors to be less than 10msec versus the current (2+ seconds).

Follow current recovery procedure when such an error is detected.

1) Shutdown the link that reported the errors

2) If all Humvee links on the PXM report errors, raise a non-fatal error against the PXM. If PXM redundancy is available, switch to the standby PXM card.

Switch Fabric errors

Isolate local Switching Fabric errors before reporting failure to the PXM. Speed up detection/isolation of Switching Fabric SFRAME errors to be less than 10msec versus the current (2+ seconds).

Follow current recovery procedure when such an error is detected.

1) Shutdown the link that reported the errors

2) If all links going toward an SM card fails, move the SM slot to degraded mode, and if redundancy is available on that SM, switch the standby SM to be active.

3) If all links reported error on a card, leave the last failed link up. (new)


This feature is available only for the MGX 8850 switch with the PXM45 controller.

Cell Bus Path Fault Isolation and Recovery

The service modules and the controller cards use the Cell Bus for almost all the inter-card communication. One aspect of inter-card communication involves the active controller card periodically polling the service modules to detect service module failures. So, any failure to use the Cell Bus results in major failure in the system. In Release 3.0.20, the firmware has been enhanced to offer better procedures for detection, isolation and limited recovery from the failure of the hardware components that are specific to using the Cell Bus path.

The Cell Bus Path fault is isolated to the PXM if its polling of all Service Modules and the standby controller card in the node fails. Once the fault is isolated to the active PXM, the Active PXM is reset to initiate a switchover and recover from the failure.

Enhancements for Release 3.0.20

The product enhancement requests (PERs) in Table 2 were introduced in Release 3.0.20.

Table 2 List of Product Enhancement Requests in MGX Release 3.0.20 

Enhancement Number
Purpose

2834

A dsphotstandby command which, when entered on the AXSM, would check for the readiness of the standby AXSM. This would ensure that a switchover to the standby AXSM would be safe.

7419

Two new CLI commands, dspportrtcnt and clrportrtcnt, are being added as a way to display the real-time statistics in both ingress and egress directions and to clear these statistics, respectively.

FRSM-12-T3E3 Online Diagnostics

This feature provides the capability to configure a hardware-oriented test to check the health of the FRSM-12-T3E3 card—both active and standby. The test can be run in active, standby, or both modes at the same time. The test is nonintrusive and runs with minimum overhead. The capability is provided as an option. The failure of online diagnostics in the active FRSM-12-T3E3 card results in a switchover to the standby FRSM-12-T3E3 card. The failure of the online diagnostics in the standby FRSM-12-T3E3 card results in declaring the standby FRSM-12-T3E3 card as failed. The failure of the standalone FRSM-12-T3E3 card results in the card being placed in the failed state but the card will not be reset.

This feature is available for the MGX 8850 switch with the PXM45 controller.

MGX-SRME

This feature provides channelization and redundancy support for MGX-VISM-PR in a MGX 8850 (PXM45) chassis. The MGX-SRME card can take one OC-3 or one STM-1 as ingress, channelize the signal to a T1 or an E1 and distribute to an MGX-VISM-PR 8T1 or an MGX-VISM-PR 8E1 card via a distribution bus inside the MGX 8850 (PXM45) chassis. For redundancy, a MGX-VISM-PR card can be configured as a standby card, so if one active MGX-VISM-PR card fails, MGX-SRME reroutes the traffic to the standby card. MGX-SRME also provides automatic protection switching (APS) capabilities on the ingress line. If one line fails, the other line takes over. APS protocols include GR-253, ITU-T Annex A and Annex B.

The MGX-SRME card is supported in the MGX 8830 and the MGX 8850 switches.

MGX-VISM-PR-8T1/8E1

This feature provides support for the MGX-VISM-PR-8T1/8E1 card on the MGX 8830 platform, and provides the capability for voice applications in this switch.

The MGX-VISM-PR-8T1E1 card is supported in the MGX 8830 switch.

Alarm Filtering

The Alarm Filtering feature works in conjunction with Cisco WAN Manager (CWM) 11.0.10 to display a filtered integrated shelf alarm. The filtered integrated shelf alarm ignores all lines, ports, connections and feeder alarms reported by a given node. When the CWM GUI displays a group of nodes in group mode, the group's integrated alarm is the aggregation of all filtered alarms reported by the nodes in the group, and all trunk/line alarms reported by these nodes.

Enhancements in Release 3.0.10

The product enhancement requests (PERs) in Table 2 were introduced in Release 3.0.10.

Table 4 List of Product Enhancement Requests in MGX Release 3.0.10 

Enhancement Number
Purpose

2291

The persistent topology feature provides CWM with a persistent view of the network, regardless of the current operational status of the nodes in the network. Topology information (IP address, node ID, feeder port ID, etc.) is stored in the persistent topology database for each node in the network. If a node is disconnected from the network due to some error scenario (the link went down, the node rebooted, etc.), CWM would still be able to retrieve information about this node from the persistent topology database. Starting with this release, the persistent topology database contains information on the routing and feeder nodes in the network.

5055

CLI commands provided to display VC/CoS thresholds in the AXSM-E QE. This feature is available for the MGX 8850 switch with the PXM45 controller.

5068

dspport on AXSM-E card and dsppnport on PXM card should display the same number of SVCs. This feature is available for the MGX 8850 switch with the PXM45 controller.

5267

Better clock resolution provided for tstdelay on AXSM-E cards. This feature is available for the MGX 8850 switch with the PXM45 controller.

About the New MGX 8830 Switch

The Cisco MGX 8830 is an attractively priced 1.2 Gbps switch for sites with power and size constraints. It allows our customers to extend their geographic reach to more remote locations that need the high availability and features of the MGX 8850 in a smaller footprint.

The MGX 8830 supports interface modules for Frame Relay, ATM, Circuit Emulation, IP and Packet Voice.

New with the Cisco MGX 8830 is the industry's first ATM Modular optics, enabling service providers to mix and match single-mode, multi-mode and intermediate reach fiber on Broadband ports. Service providers can also add the broadband ports as needed, minimizing CAPEX.

About the New MGX 8850 (PXM1E) Switch

The Cisco MGX 8850 Multiservice Switch -- with the new PXM1E processor card -- is a low end, cost-effective multiservice switch based on the current MGX architecture with integrated network interfaces on the processor card. Like the MGX 8830, the switch will provide a mix of broadband and narrowband services in addition to PNNI routing. It scales from DS0 to OC-3/STM1.

The PXM1E-4-155, PXM1E-8-T3E3, and the PXM1E-T3E3-155 cards are supported in the MGX 8830 switch and the MGX 8850 switch with the PXM1E controller.

ITU APS on AXSM/B and AXSM-E for PXM45

APS provides redundancy on SONET/SDH equipment to protect against line failure or fiber cut. APS permits the network to react to failed optical lines and/or optical interfaces by switching to an alternate line. This release supports the international standards ITU-T G.783 Annex A and B APS on AXSM/B and AXSM-E optical modules. APS 1+1 intercard redundancy requires use of an APS connector (MGX-APS-CON) to connect adjacent back cards.

The complete list of architecture mode supported by software is:

1+1 GR253

1:1 GR253

1+1 G.783 Annex A

1:1 G.783 Annex A

1+1 G.783 Annex B

ITU-T APS on AXSM/B is supported on the MGX 8850 (PXM45) and the MGX 8950 switches. ITU-T APS on AXSM-E is supported on MGX 8850 switch with the PXM45 controller.

Benefits

For a line failure, the detection and signaling of the failure occurs within 10 ms and the switchover occurs within 50 ms. For a card failure, the recovery will occur in less than 250msec. Using APS is a faster way to recover than can be achieved with Y-cable redundancy or ATM layer rerouting.

MGX-RPM-XF-512 Card

MGX-RPM-XF-512 is the next generation RPM card based on Cisco Patented Parallel Express forwarding (PXF) technology. Service Provider customers can use MGX-RPM-XF-512 to IP enable their FR/ATM infrastructure to provide high touch services like IP VPN's using MPLS with line rate QOS.

DSL Access Support — Single-ended SPVC Configuration

The feature enables configuration of both the endpoints of the SPVCs at the master end of the connection. With the feature, the connection needs be provisioned using the double ended provisioning model. The slave end of the connection is activated when the connection is established by the master end. This feature provides the ability to provision single-ended SPVC connections that originate on the DSLAM.

The Single-ended SPVC Configuration feature is supported on the MGX 8850 (PXM45), MGX 8950, MGX 8830, and MGX 8850 (PXM1E) switches.

Benefits

This feature enables improved interoperability with other vendor equipment and management stations.

250K Connections

The 250K Conns feature improves the scalability of the existing PXM45 node from the current 100K connections to 250K connections. This feature is supported only on the version B of the PXM 45 card with 256M of memory. On a single node, there can be a maximum of 250K SPVC/SPVP and SVC/SVP connections, where a maximum of 100k connections are persistent, and the other 150K connections are non-persistent. However, a node will support 250k persistent connections if it is not managed by CWM.

The number of persistent connections are limited by the number of connections supported by CWM, which is currently 100K.

The 250K Connections feature is supported on the MGX 8850 and MGX 8950 switches with PXM 45 version B cards.

Benefits

Customers can provision more connections on each switch.

Path and Connection Trace

The Path and Connection Trace feature allows the user to determine the path taken by a connection. The Path Trace feature is used for new connections in the process of being established. The Connection Trace feature is used to collect information on existing connections that have already been established. The Path and Connection Trace feature supported in the previous releases is based on the pre-standard version of the ATM Forum specification. In the current release the Path and Connection Trace feature will conform to ATM Forum standard PNNI Addendum for Path and Connection Trace, Version 1.0 af-cs-0141.000.

The Path and Conn Trace feature is supported on the MGX 8850 (PXM45), MGX 8950, MGX 8830 and MGX 8850 (PXM1E) switches.

Benefits

Standards based feature enables interoperability with other vendor equipment.

Network Clock Distribution Protocol (NCDP)

Network Clock Distribution Protocol (NCDP) is the means by which an accurate clock source is chosen by a node and is distributed to the rest of the nodes within a network for the purpose of ensuring synchronized network operation. NCDP based clocking provides resiliency of clock sources in a network which is vital for delay-sensitive traffic like video and voice traffic and allows the network to proactively switch clock sources rather than waiting for the quality of the active clock source to degrade.

NCDP is disabled by default. The only configuration required to enable the clock distribution is to enable it, then add the clock source references. NCDP can be turned off on a nodal basis or an interface basis. NCDP supports clock distribution to 200 nodes in the network. If the network is larger than 200 nodes, it should have multiple clocking domains with separate clock sources.

NCDP is supported on the MGX 8850 (PXM45), MGX 8950, MGX 8830, and MGX 8850 (PXM1E) switches.

Benefits

The implementation of NCDP based clock distribution on the MGX 8800 enables service providers to deploy large scale networks with integrated clocking suitable for delay sensitive data transfer.

Simple Network Time Protocol (SNTP)

Simple Network Time Protocol (SNTP) based time of day synchronization enables MGX 8800 nodes to have network time synchronization. Accurate time of day service is provided by synchronizing to Universal Time Coordinated (UTC) time. The standard based approach allows the switch to synchronize to any SNTP/NTP time server. This provides accurate time for statistics and alarms generated on the switch and enables accurate synchronization of such events between switches. The BPX uses a similar protocol for time distribution, but with the addition of SES, the BPX can also be synchronized using SNTP. In a network of BPX 86xx and MGX 88xx switches, time must be set on the BPX in order to be distributed consistently throughout the network.

SNTP is supported on the MGX 8850 PXM45, MGX 8950, MGX 8830 and MGX 8850 (PXM1E) switches.

Benefits

The SNTP Server functionality allows MGX 88xx and BPX 86xx switches to act as SNTP servers for the network.

Priority Routing

Priority based routing allows customers to specify the priority of connections. The priority allows high priority connections to be established before low priority connections. During failures, the high priority connections are also released before low priority connections. This action enables rerouting and reestablishment of high priority connections earlier than low priority connections.

This feature is supported on the MGX 8850 (PXM45), MGX 8950, MGX 8830, and MGX 8850 (PXM1E) switches.

Benefits

The customer can offer prioritized services based on connection priority.

Per Connection Overbooking

The Per Connection Overbooking feature for SPVCs provides improved control of network utilization for multiple tiers of service on a network supporting various trunk capacities. The percentage utilization factor is used for Connection Admission Control for the connection. The actual bandwidth used for Connection Admission Control for the connection is based on the PCR/SCR configured for the connection and the percentage utilization factor configured for the connection, combined with the percent utilization configured for interfaces in the selected path.

Overbooking means that less bandwidth is reserved for a connection, however it can use more bandwidth. The feature will enable overbooking to be performed on a connection basis.

Per Conn Overbooking is supported on the MGX 8850 (PXM45), MGX 8950, MGX 8830, and MGX 8850 (PXM1E) switches.

Benefits

This feature enables service providers to provide differentiated overbooking on a per connection basis rather than only on a uniform basis allowed by interface overbooking.

Preferred Routing

Preferred routing of connections provides the network operator a means of bypassing the PNNI route selection, and configuring a specific path through the network by which a connection will follow. Preferred routes can be configured as either Preferred or Directed routes. A Preferred route is a route which will follow the configured path if available, but will revert to a PNNI-selected route if the preferred route is not available. A Directed route is a route which will follow only the configured path; if the configured path is not available, the connection will remain unrouted.

In this first implementation of Preferred routes, a set of preferred routes is configured and assigned reference numbers, referred to as route sets. As connections are configured, they can be assigned to a particular route set. Each route set can currently contain one preferred (or directed) route.

Preferred routes can currently be specified only across a single PNNI peer group.

Since the preferred route is placed in the PNNI DTL by the source node, preferred routes are interoperable with any standard PNNI implementation.

Preferred routing is supported on the MGX 8850 (PXM45), MGX 8950, MGX 8830, and MGX 8850 (PXM1E) switches.

Benefits

The customer can control the selection of routes based on criteria other than those allowed in the route selection algorithms offered by PNNI.

Clear Service Module Configuration (clrsmcnf)

The clrsmcnf feature clears the configuration for a particular service module slot without affecting the configuration of other slots. This feature clears the configuration from both memory and disk (persistent). The clrsmcnf command will be a blocking command and the service module will be unavailable for provisioning during the entire duration of the command.

The clrsmcnf feature is supported on the following modules.

MGX 8850 (PXM45): AXSM, AXSM/B, AXSM-E, RPM-PR, MGX-RPM-XF-512

MGX 8830 and MGX 8850 (PXM1E): FRSM, AUSM, CESM, VISM, RPM-PR

Benefits

The clrsmcnf feature does not impact or clear the configuration of the entire shelf (clrallcnf), it only clears the configuration for a particular slot thereby limiting the impact.

Disk Sync Verify

This feature provides a verification utility to check the synchronization of the disk "data" between the active PXM and standby PXM hard disks in the D:/DB2 directory. This disk synchronization verification utility provides a method of checking the "data" between the active PXM and standby PXM hard disks when invoked through CLI. This new CLI command, dskdbverify, invokes the task of verifying the "data" between the active PXM and standby PXM hard disks. This CLI command can be invoked both on the active PXM and standby PXM.

AXSM and AXSM-E Virtual UNI

A new port type called Virtual UNI (VUNI) is defined in addition to the already defined port types - UNI, NNI, VNNI (Virtual Trunk). This feature benefits both the MPLS and PNNI control plane.

Virtual UNI is supported on the MGX 8850 (PXM45) and MGX 8950 switches with the AXSM, AXSM/B, and the AXSM-E line cards.

Benefits

Customers can provision multiple Virtual ports each with a VP range on one physical line and thus allow transport of PNNI SPVPs. This feature removes the restrictions in previous releases with Virtual Trunks (VNNI) wherein only one VP could be defined so only SPVC could be transported across those VNNI interfaces. With Virtual Port an MGX, that is not configured with MPLS control plane (LSC) but is expected to transport PNNI and MPLS traffic to a neighboring switch configured with both MPLS and PNNI, can utilize this feature by defining a combination of VUNI (0-255 VP range) or VNNI (0-4095 range) or a VNNI (one VP only) on a single Physical ATM port thus allowing trunking as well as terminating traffic on a single physical port.

Virtual port allows the flexibility of defining separate Service Class Templates per logical Virtual port. This allows customers to engineer different behaviors of traffic on different logical ports on the same physical line.

Persistent Topology

The Persistent Topology feature enables CWM to maintain a persistent topology information of the entire network. One or more nodes will be designated as gateway nodes. Whenever CWM needs info about the network, it will query gateway nodes to collect necessary information. Gateway nodes are defined to be nodes from which CWM can query for information on the nodes contained within a peer group. A node needs to be configured to be a gateway node in every peer group through CLI or CWM before it can be used as one.

This feature will deliver the following functionality:

Cumulative collection of node info for topology database. Node info will contain nodeId, nodeName, lanIP, atmIP, sysObjId.

Allow manual configuring (i.e. enabling and disabling) a gateway node through CLI.

Allowing manual deletion of a node info from the topology database.

Support redundancy of the cumulative topology database.

Benefits

This feature is useful to monitor the entire network as information of all the nodes irrespective of their state will be available to the CWM. It enables service providers who deploy large scale networks to keep track of the all the nodes in the network.

SCT File Management and User-Configurable Names

This features implements version control for the SCT files such that the SCT files can have a major version, which would keep track of the parameters being added/deprecated, and a minor version to address limitations. A SCT management MIB was created to keep CWM and the switch in sync with respect to the MIBs. The SCT MIB contains a version parameter, and can be used to convey the minor and major versions of the SCT file. When the SCT file is modified by the user, the user can save the file as a new file or as a different version of the SCT file.

Detection of Non-native Controller Front Card and HDD Card

With this feature the runtime firmware detects when a controller front card or HDD card from another shelf/node is inserted into a node in the standby controller card slot. When the firmware detects a non-native PXM1E front (that has hard disk) or HDD back card is inserted into a node in the standby controller card slot, all the contents, except the contents in the C:FW, C:SCT, F:SCT and the image files and auto configuration files in the E:RPM, on the hard disk in the standby controller card slot will be deleted and the event log files will be backed up.

In other words, when a non-native hard disk is detected in the standby controller slot, the following files and directories will be preserved, event log files are backed up and everything else, including event log files, will be deleted on the non-native hard disk:

C:FW

C:SCT

F:SCT

all files except auto configuration files in E:RPM directory

As a result of this feature, the hard disk on the standby controller slot no longer needs to be manually cleaned up when it is moved from another shelf/node.

Enhancements in Release 3.0.00

The product enhancement requests (PERs) in Table 2 were introduced in Release 3.0.00.

Table 6 List of Product Enhancement Requests in MGX Release 3.0.00 

Enhancement Number
Purpose

124

This feature provides a verification utility to check the synchronization of the disk data between the active PXM and the standby PXM hard disks in the D:/DB2 directory. This utility provides a method of checking the "data" between the active PXM and the standby PXM hard disks when invoked through the CLI.

1087

Since the MGX 8850 with PXM45 is used as a core switch and that switch does not have a time of day/date distribution, the switch needs to provide support for Network Time protocol (NTP - RFC 1305). Accurate time of day is needed by customer operations to correlate events on multiple switches as well as network management and with customers.

1473

AXSMs, when APS is configured, is bridging the SONET line instead of just section and path as specified in ANSI T1.105.

1557

This extension of VNNI functionality - by permitting the assignment of VPI range instead of a single VPI would benefit lots many customers. Currently, we have following possible config on an AXSM line: - A NNI port, over which you could run PNNI and assign the full 0 -4095 VPI address range. - A UNI port, you have a VPI range 0-255 for terminating connections. - Multiple VNNI ports. Initial definition requires specifying a VPI assignment for the port. You cannot terminate connection on an NNI port. Neither can you route PVP through a VNNI interface. These restrictions have the potential of affecting our customer's business decisions. Implementing this PER will eliminate the above listed constraints on an AXSM port.

1609

The community read string on 8850 was changed to something other than public to close a potential security hole/violation.

1663

This feature is included support ITU-T O.151 based segment OAM loopback test feature.

1092

The conntrace command currently is not synchronous and the prompt is sometimes returned prior to the trace output. The request is to have conntrace command provide a timeout per hop and also to provide an output that shows when the command failed due to a time out. The timer per hop can be up to 5 seconds. Also, the results of the command should be placed at the end of the command display. In addition, a field showing the Terminating InterfaceID should also be provided before the field showing the Terminating Interface VPI.

2182

The Cisco MGX 8850/8950 did not offer a way to configure a preferred route for any connection. Instead the PNNI routing engine configures the route across the network based on configurable routing policies. This feature is available on other Cisco PAR platforms (BPX/IGX) and is used frequently by customers. Customers require the ability to configure a preferred route per connection (VC and VP), and the ability to configure a direct preferred route whereby if the preferred fails the connection is not re routed.

2193

This features implements version control for the SCT files such that the SCT files can have a major version, which would keep track of the parameters being added/deprecated, and a minor version to keep track of modifications to parameters. A SCT management MIB was created to keep CWM and the switch in sync with respect to the SCT files in a node. It also helps CWM in getting the operational status of a SCT file.

2291

The persistent topology feature enables CWM to maintain a persistent topology information of the entire network.

2500

User configurable names for specific SCTs can be entered using CWM and is stored in the switch's database.

2509

A connection summary alarm trap is sent whenever several connections enter into alarm on a service module. The connection summary alarm trap (60306) has been replaced with a newer trap (60311) which contains additional information such as the number of VPCs and VCCs in failure.

2834

This PER tracks PER 20000123 A dsphotstandby command which, when entered on the AXSM, would check for the readiness of the standby AXSM. This would ensure that a switchover to the standby AXSM would be safe.

Limitations, Restrictions, and Notes

This section includes information about limitations, restrictions, and notes pertaining to Release 3.0.25.

Release 3.0.25 Limitations

No new limitations for Release 3.0.25.

Release 3.0.23 Limitations

Bandwidth Limitations with IMA Ports

In previous 3.0.x Releases, for IMA NNI ports, when there is a change in the available IMA bandwidth (for example when one T1/E1 line in the IMA group goes down), PNNI does not learn nor advertise the change in bandwidth. As a consequence, SVC and SPVC connections are accepted when there is not enough bandwidth. Also, if the bandwidth has gone down even below the sum of the connections that have already been committed, no action is being taken. The result is that we loose data traffic on all the connections.

To rectify the above stated problem, starting with Release 3.0.23, the Service Module will inform the controller of the bandwidth reduction and we will be releasing the required number of connections such that the current usage is equal to or lesser than the new physical bandwidth. There is no guarantee that the same connections will be released at both sides of the trunk. To ensure this we will have to initiate the release from only one side of the trunk.

For the different types of trunks (PNNI, IISP and AINI) the following conditions will be used to decide whether the local node has to initiate the release of the connections:

IISP: This side of the link is configured as the network_side.

PNNI: The local node has a higher nodeId than the node at the other end of the trunk.

AINI: vpivcialloc option has been enabled for this side of the trunk.

The following commands can be of used to identify the problem:

dspimagrp - Specifies the Avail Cell Rate (c/s) in the IMA Groups.

dsppnportrsr - Specifies the Available BW used in the PNNI port.

dsppnni-idb - Specifies the Available Bandwidth (AvCR) advertised by PNNI.

dsppnni-ptse -detail true - Specifies the PNNI database, including the Horiz Links and their respective AvCR.

The solution to initiate the release of connections from the node with the higher node ID for a NNI link might not always work. Consider the following scenario:

1) One end of the IMA trunk is configured with a higher maximum cell rate than the other end. The end of the trunk configured with the higher maximum cell rate is hosted on a node with a higher node ID and the other end with the lower maximum cell rate is on a node with a lower node ID.

2) This trunk has connections routed, which have used up till the maximum cell rate on the end with the lower maximum cell rate.

3) Now if there is a IMA link loss in the IMA group, it will result in the maximum cell rate going down at both the ends. On the node with the higher node ID if this new maximum cell rate is still greater than what is used, this node will not initiate the release of the required number of connections. As a result of this data traffic will be lost on all the connections.

The latter limitation applies to IISP and AINI trunks as well:

1) If the side of the IISP link configured as the "network_side" has a higher maximum cell rate.

2) If the side of the AINI link configured as the "vpi/vci-allocator" has a higher maximum cell rate. (refer to Caveat CSCea14630)

Release 3.0.20 Limitations

AXSM-E OAM

If the connection is in the ingress (remote) loopback mode, then the connection can receive OAM loopback cells up to the line rate (as long as the policing policy permits).

If the connection is not in the loopback mode and is operating in the normal mode, then the AXSM-E card can receive up to 8K OAM loopback cells per second. Any excessive OAM loopback cell will dropped. This limitation applies for all the connections.

For example, if there is only one connection, then that connection can receive 8K loopback cells per second. If there are 9K connections on an AXSM-E card and one OAM loopback cell per second is being pumped through on each connection, then there can only be up to 8K connections to receive loopback cells at any given second, and the additional 1K connections would not receive for that second.

The limitation is 8K OAM loopback cells is per card and not per connection. Also, only OAM loopback cells pumped from the line on the ingress side of an endpoint can be handled. OAM loopback cells from the egress side are not handled because OAM loopback cells from the egress side can only be initiated by the CLI.

CLI Configurable Access

Not all CLI commands are allowed to be changed and a command cannot be changed to CISCO_GP group access level.

Only the switch software is allowed to generate the binary file. This file has an authentication signature which has to be validated before the file can be used. Any manual changes to the file would make the file void.

If the binary file becomes corrupted, then the command access levels revert back to the default values during the card bring-up. To recover, repeat the installation process or retain a copy of the binary file and do cnfcli accesslevel install on that service module.

Currently, command names are verified, but an invalid command name may be parsed and be added to the binary file. However, this invalid name would be ignored later.

If replication to standby failed, the installation process failed.

cnfcli accesslevel default restores all command access levels to default for the service module that this command is executed on. It does not remove the binary file and this change is not persistent. If it is executed on the active card of a redundancy pair, the standby card is not affected. When the card is reset and the binary file exists, it will configure from the binary file when it is brought up.

Controller Card Mastership Sanity Verification

Because the solution provided in this release can only detect and log invalid mastership state transitions, an outage may still occur.

Serial Bus Path Fault Isolation

The Serial Bus Fault Isolation feature only addresses isolating errors on the local cards. However, when a common error occurs on the switching fabric card, this solution does not address this. As a result, if there is a problem on the PXM card or the XM60, the fault is going to be reported against all cards that detected the symptoms of this problem.

Cell Bus Path Fault Isolation and Recovery

The isolation procedures can isolate the Cell Bus path involving the QE SAR that is used for polling the Serial Bus based Service Modules (e.g., AXSM, AXSM/B, AXSM-E,) and all the communication with the standby controller card and the Cell Bus Based Service Modules (e.g., FRSM, CESM). These procedures can't isolate the Cell Bus path failures involving ATMizer SAR that is used for the inter-card communication except polling, between the active controller card and the Serial Bus based Service Modules (e.g., AXSM, AXSM/B, AXSM-E).

The isolation procedures isolate the Cell Bus path failures to the active controller card only. This means, it is determined whether the active controller card has the fault for the inter-card communication over the Cell Bus from the active controller card to the Service Modules and the standby controller card or not. It does not isolate the fault if the active controller card fails to communicate with some cards and successfully communicates with the rest on the Cell Bus.

There should be at least 2 cards (2 Service Modules or 1 Service Module and 1 standby PXM) for the isolation procedures to be able to isolate the Cell Bus path failures to the active controller card.

Only the failures detected by periodic polling triggers the isolation procedures. Failures reported from other sources in the system against a Service Module or the standby controller card due to the Cell Bus path failures don't initiate the isolation procedures, and which results in resetting that card against which the failure is reported, even while the active controller card is in the process of isolating the Cell Bus path failures triggered by the polling failures.

There is no separate trap/alarm generated against the active controller card Cell Bus path when the fault is isolated to the active controller card. Only the event logs will be available that can be used during the manual investigation triggered by the card reset and/or switchover traps.

If there is no controller card redundancy available, isolating the Cell Bus path failure to active controller card results in outage as the active controller card will be reset.

FRSM-12-T3E3 Card

Because of the hardware limitation of the current FPGA Egress Frame Engine in the Frame Relay Service Inter-Working mode, the egress aggregate cell rate should not go over the DS3 rate (104,268).

For example, assume that there is an SPVC connection with a maximum CIR (44,210,000) provisioned between a port on a FRSM-12-T3E3 card and a port on a AXSM card in a same node. On the FRSM-12-T3E3 side the connection is configured as in mode chanType = 3 (frSIWtranslate:Frame Relay Service Inter-Working, translation).

If the AAL5 PDU traffic pumped into the connection of the AXSM port (for example from an AdTech tester) is coming in at a rate higher than DS3, the Egress Frame Engine may not be able to handle this high rate and the encapsulation translation error may occur.

The default DE to CLP and CLP to DE mapping in the CLI command addcon, which are "mapCLP" and "mapDE", are taken from the SCT 0 file instead of the SCT files associated with the port. This happens for the following FR channel types:NIW, NIW replace, SIW transparent, and SIW translation. To make the mapping consistent with the default values in the SCT file, you need to use SNMP MIB chanDEtoCLPmap, chanCLPtoDEmap or CLI options -demap, -clpmap to set the values. (Refer to caveat CSCdz47385.)

When issuing the CLI command cnfpart -lcn <#lcns>, the wrong error code is returned when the configure resource partition command cnfpart is issued when the number of logical connections is greater than the available logical connections on the card. The error code from the cnfpart command should be:

ERR:Cannot allocate requested LCNs for partition

But the following error message is displayed:

ERR:Cannot modify LCN range due to configured connections

(Refer to caveat CSCdz47806.)

If you disable LMI on a port, then enable/configure it again, the LMI counters are not re-initialized. The previous LMI counts and errors will be added to the new ones. A simple workaround is to clear the counters on the port. (Refer to caveat CSCdz30469.)

Release 3.0.10 Limitations

AXSM-32-T1E1-E Card

Only 10 SVC calls per second is guaranteed.

FDL support for loopback code detection is not supported.

Far-end line performance counters are supported only for the E1 interface. They are not supported for the T1 interface.

HMM support is not available for IMA-32 and the Framer devices.

IMA link alarms, LIF and LODS integration times are not configurable.

An IMA group configured for Version 1.1 does not fall back to Version 1.0 if the far-end IMA group is configured with Version 1.0.

Auto-restart (persistent Rx IMA ID) feature is not supported.

When there is a switchover, it can take up to 3.5 seconds for the IMA groups to recover. Data is lost until the groups recover.

Support for UNI and virtual trunking on IMA groups is not available. But UNI and virtual trunking on non-IMA T1/E1 ATM lines is available.

Support for UNI IMA is not available.

IMA group cannot have links from the upper and lower bays together.

ITC clocking mode on IMA is not supported.

Transmission delay of more than 500 ms on the T1/E1 IMA links is not supported.

GTSM (Group Traffic State Machine) up and down integration times should be configured to values of 0 (zero) only.

There is a 5-ms fluctuation on IMA delay tolerance.

While the IMA group accumulated delay is being removed with clrimadelay, the following apply:

Any changes to this IMA group configuration at NE are blocked.

Any changes in the FE IMA links in this group can cause the NE IMA group to restart.

The VC and COSB thresholds are updated as and when the links are added or deleted from the IMA groups. The thresholds for the connections added when there are N links in the group can differ from the connections added when there are (N+1) links in the IMA group.

Round trip propagation delay of more than 1 second on IMA links is not supported.

The CLI clrimadelay or the corresponding SNMP set operation is issued to remove accumulated delay from an IMA group. While delay is being removed, the following CLIs must not be executed. They will return error if issued. The corresponding SNMP set operations will also be rejected:

delimagrp

cnfatmimagrp

cnfimagrp

upimagrp

dnimagrp

rstrtimagrp

addimalnk

clrimadelay

startimalnktst

cnfimalnktst

stopimalnktst

delimalnk

Any of the following operations can extend the delay removal completion by 9 seconds.

IMA link deletion at *FE*

IMA group restart at *FE*

IMA link transition into Unusable state at *FE*

IMA link entrance into LIF failure at *NE*

Then the group will be restarted and it may take another 3 seconds to become operational. The group will be restarted even if the delay process completes sooner and any of the operations listed above occurs.

GTSM (Group Traffic State Machine) UP and DOWN integration times should be configured to a value of 0 for all IMA groups. Any positive value, especially the UP time, will delay the operational state of any port(s), configured on the IMA group, from becoming active. This can cause more than desired traffic loss during a card switchover.

BERT is supported only on the T1 interfaces. It is not supported on the E1 interfaces.

Sub-slot and port identifiers do not correspond to the exact physical attribute for IMA and channelized interfaces as they used to in the old unchannelized interfaces. Refer to the DDTS issue CSCdy08500 for more information. The following apply to the AXSM-32-T1E1-E card in Release 3.0.10:

If the logical port on the SM is deleted, the corresponding pnport on the controller, that is, PXM45, should be deleted.

The port number in the pnport (shelf.slot:subslot.port:subport) could be a random number. The user should not interpret this number as line or IMA group number.

PXM1E-16-T1E1 Card

Only 10 SVC calls per second is guaranteed.

This can cause more than desired traffic loss during a card switchover.

BERT is supported only on the T1 interfaces. It is not supported on the E1 interfaces.

PXM1E Cards

The maximum number of connections on the PXM1E cards (except for the PXM1E-16-T1E1 card) is 27K, and the maximum number of ports on these cards (except for the PXM1E-16-T1E1 card) is 4K.

The dspapsbkplane command does not work for the PXM1E-4-155 card.

An LOS condition on an APS line will not be reported by the dspalms command if both the following are true:

The PXM1E card has SONET lines, and

Either the APS line with the LOS condition is the Protection line for intracard APS, or the APS line with the LOS condition is the adjacent back card line for intercard APS. For example, if line 1 on slot 7 is the Working line and line 1 on slot 8 is the Protection line, then an LOS on line 1 in slot 8 will not be reported when dspalms is issued on slot 7, assuming slot 7 has the Active front card. The dspadjlnalm command will also not report LOS in this situation.

All other conditions (LOF, OOF, etc.) are reported correctly (refer to caveat CSCdy30310).

For uplink ports on all PXM1E cards, the standby controller card is not able to derive clock signals from the standby uplink port (daughter card) due to a hardware limitation. No data signals can be received on the standby card and clock signals cannot be recovered. On switchovers, the uplink clock sources will be requalified (refer to caveat CSCdy68971).

When a back card is inserted or removed, verify that the back card is accessible by reading a register on the back card. If the front card is not able to read the register, the back card will be put into the mismatch state. If the problem happens on the active card and if the standby card is available, card will be switched over. Otherwise the back card is put into mismatch state. If the problem also happens on the standby card, the backcard will be put into mismatch state. A message will be put into dsplog to show that the back card is not considered to be in a healthy state. This message should be ignored when it is logged when the card is in the Init (I) state. Only messages logged in either the Active (A) or Standby (S) states are valid.

When intercard APS is configured, the active front card takes control of the standby back card. The standby front card will not be able to determine the local back card health because it does not have control of its own back card. When intercard APS is configured for the PXM1E-COMBO (also known as PXM1E-T3E3-155) card, and if all the SONET lines on the standby card displays an alarm, the shellcon function dspAdjBcHealth(0) should be used to determine the alternate back card's health. This back card health detection is available only for the PXM1E-COMBO card (refer to caveat CSCdy39859).

PXM1E Online Diagnostics

Online diagnostics uses VPI=32 and VCI=31 for a connection setup. No other connection (data or control) should use this VPI/VCI pair. Using this VPI/VCI pair may result in the failure of the online diagnostics (if enabled) and the card will subsequently be placed in the failed state.

MGX-SRME Card

MGX-SRME APS provisioning will be blocked on all unsupported PXM45 cards and a proper warning message displayed.

This feature provides the capability to guard against fiber cut and line failures. It minimizes the traffic loss by switching to the protection line when it detects a problem on the working line.

This feature relies on the interrupt line coming from the MGX-SRME card to the PXM45/B. PXM45/B boards have an interrupt line to MGX-SRME card. MGX-SRME APS will work only on PXM45/B having 800-level part number equal or greater than 800-09266-03.

FRSM-12-T3E3 Card

On an FRSM-VHS, all connections on a port with LMI enabled will have those connection statuses initialized to okay. If the connection is actually in LMI abit alarm, then the connection alarm will be updated to the correct state (LMI abit alarm) via asynchronous updates or the periodic full state update. On a resetcd on an FRSM-12-T3E3 card, all connections on a port with LMI enabled will have those connection statuses initialized to LMI abit alarm. If the connection is actually okay, then the connection alarm will be updated to the correct state (okay) via asynchronous updates or the periodic full state update. In either case, the connection alarm will be updated to the correct, current state. For the FRSM-VHS card, it starts in the okay state, and for FRSM-12-T3E3 card, it starts in the LMI abit alarm state (refer to caveat CSCdy28727).

For the cnfchanstdabr command, because of a hardware limitation, the NRM (number of cells per forward RM) range is now 4 to 256 (refer to caveat CSCdy05769).

FRSM-12-T3E3 Online Diagnostics

Online diagnostics can only detect problems; it does not have the capability to isolate problems.

AXSM-E Double Density

With the AXSM-E double density feature, the total bandwidth supported by each Service Module without blocking is 622 Mbps.

AXSM Cards

Do not enable offline diagnostics on AXSM cards in the APS 1+1 Op A mode. A possible loss of signal will occur when offline diagnostics are run on the AXSM cards in this configuration (refer to caveat CSCdy62950).

For AXSM OC-3 cards running in the Op B mode, a remote card switchover can occur by doing setrev on a local node. This problem occurs when more than twelve lines are configured for APS and the setrev command is issued. The mode of the AXSM card can be found by issuing the dspcd command. The card switchover on the remote node is happening because of flooding of several interrupts occurring on all the lines. The cause of the interrupt was the reset of both the cards on local node (refer to caveat CSCdy09027).

APS is supported on AXSM-1-2488/B after upgrading the card to Release 3.0.00 and up, and enabling the card to operate in the Op B mode.

The dspapsln/dspapslns/dspalms/dspalm commands on a standby AXSM card do not show the results consistent with an active card. When the cards are operating in the Op B mode (which can be found by issuing the dspcd command on an AXSM card), the standby card does not perform the alarm integration and APS is also not enabled on the standby card. All the defects or failures and statistics are dynamic events which are not sent to the standby card—the standby card is unable to show the correct faults as shown by the active card. These commands are not blocked on the standby card as these are useful for debugging purposes (refer to caveat CSCdx63098).

When there is an APS line between an AXSM card in the Op A mode and an AXSM card in the Op B mode, the working and protected lines can go into the SD (signal degraded) mode if the cards are set up for 1:1 intracard APS and SD is set to -7 upward. The problem is seen because of the behavior of the AXSM card in the Op A mode, and the problem exists only between an AXSM card in the Op B mode and an AXSM card in the Op A mode; it does not exist if both AXSM cards are in the Op B mode or in the Op A mode.

Whenever a switch is made on the AXSM card in the Op A mode, it does the bridging to the other line on which a switch is going to happen. In this duration, the AXSM card in the Op B mode notices the change in the BER count and although the BER count is very small, it is sufficient to declare Signal Degraded (SD) because of having the SD threshold set at -7 (refer to caveat CSCdy31269).

A standby AXSM card cannot sync up with an active AXSM card after loadrev to Release 3.0.10 if the redundant AXSM card has NNI ports and 40k connections configured, and both cards the 2.0(15.2) image. In the 2.0.x release, the LCN could be 0 but in later releases the ATLAS LCN 0 has been taken out from the pool. So for the cards with 4 ATLASs, the problem will be seen for the following LCNs while upgrading to Release 3.0.10 (refer to caveat CSCdy36202):

0

32 * 1024 = 32768

64 * 1024 = 65536

96 * 1024 = 98304

When running in the APS Op B mode on an AXSM/B card, EM database corruption messages may be reported on line interfaces. If this situation occurs, use the following shellcon command to refresh the alarm structure (refer to caveat CSCdy24461):

emRefreshLineState <1-based bay number> <1-based line number>

PNNI Limitation

There is a limitation in the ATM Forum PNNI specification on how the crankbacks are handled by the entry border nodes. If the entry border of a peer group cannot route a call to the destination node and if the cause of blocking was within the peer group, then the entry cranks back to the next higher level (page 246, point b.1.2 in the ATMF PNNI specification). This higher level crankback is translated to a blocked node of the logical group node and so the source node processing this crankback would treat the whole peer group to be blocked. If this entry border node crankback happens on the destination peer group or if it happens on the transit peer group that is the only route to reach the destination node, then the calls will not get routed.

SCT Files

With the changes for CSCdw80282, you must FTP the SCT files for all the service modules back to the PXM45/PXM1E controller cards after a clrallcnf command is issued. These files are removed because they are considered to be nodal configuration files and are deleted from the C:/SCT and the F:/SCT directories.

With the changes for CSCdw80303, the SCT files for all the service modules are saved. The valid SCT files in C:/SCT and F:/SCT and their subdirectories are saved in a zip file along with the other configuration information. When the configuration is restored, the saved SCT files will be copied into the C:/SCT and the F:/SCT directories, and will overwrite any files in those directories.

Users should not use AXSM SCT files with an SCT ID greater than 255. If a value greater than 255 is used, CWM will not be able to syncup those SCT files.

Persistent Topology

If the node ID is changed on a remote node, then the new node ID value is automatically saved into the entry corresponding to that remote node on the gateway node. There is no longer a need to manually delete the old node ID value from the gateway node. Note that this behavior is different from Release 3.0.00.

However, if a remote node is downed, the gateway node is reset, the node ID of the remote node is changed, and the remote node is connected to the network again, the gateway node will store the new node ID as a new entry instead of overwriting the old entry with the new node ID. In this situation, the procedure for node ID change stated in the Release Notes for 3.0.00 should be used.

Reroute Call Performance Changes

For better call performance on PXM45/B cards, the following commands need to be issued after the upgrading to Release 3.0.10:

1. cnfnodalcongth -connpendlo 750 -connpendhi 1000

2. cnfnodal congth -setuphi 1000

Then perform the following commands at both ends of the NNI links:

3. confintcongth <physical port> -setuphi 500

4. cnfpnctlvc <physical port> sscop -scr 3000


Note These parameters are recommended only for the PXM45/B cards and not for the PXM45A or the PXM1E cards.


Clocking Limitations

The clock sources will be requalified when auto-revertive mode is changed using the cnfclksrc command.

The dspclksrcs command may display status as configuring on the new Active controller card just after a switchover even though the clock sources are configured and latched to one of the clock sources. However, this inconsistency in the display is transient and the display is corrected after few seconds.

The standby controller card doesn't monitor the uplink clock sources. As a result, the standby controller card doesn't generate alarm if an uplink clock source becomes unlockable. The information showed by the dspstbyclksrcs command may be incorrect for the uplink clock sources on the standby controller card.

There is no action initiated either on the Active controller card or on the Standby controller card if none of the configured clock sources is good, the time period for the hold-over mode has expired (more then 24 hours since neither primary nor secondary clock source became unlockable) and the local oscillator used for free running is not functional. However, alarms are raised and events are logged under these conditions.

Once the secondary clock source becomes the active clock source when the primary clock source became unlockable, the primary clock source is not monitored or qualified. As a result, it is not reverted to primary clock source when the primary clock source becomes stable even though auto-revertive mode is enabled. The workaround to get the primary clock source get monitored and relatched is to reconfigure the primary clock source. This will force the primary clock source to be requalified and relatched.

The controller card attempts to reprogram a clock source on the Service Module(s) if the clock source is configured to be taken from a port on a Service Module when one of the following occurs:

A Narrow Band Service Module switchover and a clock source is configured to be taken from a port on that Service Module

A Broadband Service Module switchover

A port on any Broadband Service Module is administratively upped

An active Broadband Service Module rebuild is completed

A Narrowband Service Module has rebuilt and a clock source is configured to be taken from a port on that Service Module. If the controller card fails to reprogram the clock source on the Service Module under the above circumstances, the network clocking hardware on the controller card is deprogrammed to not take the clock source from that Service Module. Under these circumstances, the clock source needs to be reconfigured to reattempt to program the clock source on the Service Module.

Additional Limitations

Starting with Release 3.0.10, when a hardware card is newly supported in a release, the core clear command should be invoked once because of a CLI limitation. On executing the core command, the display shows the current core as 2 or 3, and the core clear command needs to be executed (refer to caveat CSCdz31938).

For the MGX 8950, at least two XM60s are needed. One of the XM60s has to be on top, and has to be in slot 9 or 10.

Currently, an error message is displayed when the primary card is in the standby state and the secondary card is in the active state for 1:1 redundancy. The issue is a design limitation, and the error message "Primary card is not Active" is displayed (refer to caveat CSCdy41074).

During a burnboot command execution on an AUSM, CESM, or FRSM card, the switchredcd or switchcc commands are not blocked. Both switchover scenarios can cause the burnboot activity to terminate abnormally, which will most likely result in a damaged card.

There will be resource (LCN, VPI/VCI) leaks on UNI ports if SPVC connections are derouted while a UNI port is down due to card removal or dnport (see caveat CSCdx57063).

The switchcc command results in requalification of the primary or secondary clock sources if on the newly active card the primary or secondary clock sources were not qualified before switchcc. On the active card, the non-active clock source is requalified upon executing the switchcc, resetcd, or dnport commands (refer to caveat CSCdx30282).

The default setupHi value for PXM45A has been reduced from 180 to 120. This is the number of SETUPs that the node will admit in a second, before it starts to drop the incoming SETUPs. The default thresholds for the following controller cards remain the same:

Release 3.0.00 Limitations

Policing Accuracy for PXM1E

There is a limitation regarding the policing accuracy for the PXM1E. The policing rate is defined as 50000000/PCR. If the PCR is comparable to the OC12 line rate (1412830), the policing rate parameter is a relative small number (50000000/1412830 = ~35.38996). Because integer division is performed, the decimal values are truncated. As a result, the policing parameter cannot be calculated accurately. Moreover, the policing rate parameter is stored in an exponent (5-bits) and mantissa (9-bits) format, so this format cannot represent a small number very accurately. Combining the above two factors, a 100% accurate policing parameter cannot be configured.

To ensure that users get the rate that they have specified, the software configures policing at the next larger rate which the hardware can support. For example, if we program a connection with PCR = 1400000, the software programs the actual policing rate to be 1428571. For a worst case scenario, if the user configures a VBR2 connection with a PCR of 1400010 and the ingress user traffic is 1428570, there will not be any policing because the ATLAS would do policing at rate 1428571 only.

Refer to caveats CSCdw72256, CSCdw72459, CSCdw72971, CSCdw73652, CSCdw67564 for more information.

Maximum Threshold Accuracy for PXM45 and PXM1E

There is a limitation regarding the maximum threshold accuracy for the PXM45 and PXM1E. The Qbin threshold and VI rate are stored in the form of exponent and mantissa, and some accuracy is lost in expressing the real rate. In testing the thresholds, the lack of accuracy is compounded with both of the Qbin and VI rate (draining rate) and therefore we cannot calculate a exact 100% correct discard rate.

To ensure that the user gets the rate that they have specified, the software configures Qbin depth at the next larger rate which the hardware can support. As a result, ICG and RSD are truncated. In this example, we have the following scenario:

Refer to caveats CSCdw89558, CSCdw85738, CSCdw89101, or CSCdw89123 for more information.

PXM1E-based Switches

MPLS controller is not supported on PXM1E cards.

PXM1E clock source is supported by VISM, CESM, and AUSM narrow band service module cards. The VISM card can provide two clock sources, primary or secondary. CESM and AUSM can provide only one source, either primary or secondary.

Only SPVCs and SPVPs are supported on narrow band service modules. SVCs are not supported on NBSM.

No bandwidth CACing support on the narrow band service modules, except for the MGX-RPM-PR-256/512 which is checked against the OC-3 card rate. Bandwidth CACing is supported on PXM1E uplink port.

The maximum bandwidth to be distributed among narrow band service modules is ~OC10 while traffic on the network interfaces can achieve true OC12 line rate.

Traffic should be balanced between the cell bus controllers to achieve the OC-10 rate. The traffic should be distributed equally at a rate of about OC-5 on the two cell bus controllers. The cell bus controllers cannot load share to achieve OC-10 with one Cell Bus set at an OC-6 rate, and another cell bus set at an OC-4 rate. Anything above OC-6 will be dropped. However, if only one cell bus controller is used and the other cell bus controller is not used, then it can achieve OC-10. On an 8850, the CBCs are split between the left and right side of the chassis: CBC0 supports slots 1 to 6 and 17 to 22, and CBC1 supports slots 9 to 14 and 25 to 30. On an MGX 8830, CBC0 supports slots 3, 5, 10, and 12, and CBC1 supports slots 4, 6, 11, and 13.

The PXM1E with a UI-S3 card will drop up to 70 percent of outgoing Ethernet packets to specific switches. Use an approved Cisco hub/switch. This only applies to packets sent on the UI-S3 Ethernet interface. Known incompatible hubs are HP8000ProCurve and Netgear FS108.


Caution For narrowband service modules cards, whenever T1 or T3 cards are replaced with E1 or E3 cards, or vice versa, the clrsmcnf command for that slot must be used.

Reserved VCIs

The following are the reserved VCIs that the customer cannot provision:

vpi=0, vci=5 is used for SSCOP for UNI signaling ports (UNI, none ports do not need signaling). If it is a virtual terminal or EVUNI, then the minimum vpi and the VCI=5 are used for SSCOP.

vpi=0, vci=18 is used for PNNI RCC (if the port is not NNI, or Virtual NNI, then you do not need this).

vpi=0, vci=16 is used for ILMI if ILMI is enabled. Similarly, for virtual terminal or EVUNI, it is minimum vpi and vci=16.

If MPLS is configured it is vci=33 in the similar fashion as above.

If NCDP is configured it is minimum VPI and vci=34 for NCDP clocking.

FRSM-12-T3E3 Card

The FRSM-12-T3E3 card does not have the capability of supporting E3 signals.

CLLM will not be supported: The FRSM-12-T3E3 card can support connection level congestion through ATM EFCI. It also supports FR-ATM interworking of ECN and EFCI. Frame level congestion only happens in the rare case of full line rate sub 15-byte frames; therefore, the hardware will only support Port Level Congestion Management in the Frame Relay domain.

BERT: Not supported.

Sub-rate DS3: Not supported.

The following are port and connection limitations pertaining to the new FRSM-12-T3E3 card:

4 bytes header length with Stratcom LMI is not supported.

LMI on Frame Forwarding port is not supported.

If LMI is configured, port header length cannot be changed.

Single ended connections can only originate from FRSM12. Single-ended connections terminating on FRSM12 are not supported.

Single-ended SPVC can only originate from FRSM12-T3E3. Termination on SPVC of single-ended SPVC is not supported.

chanType cannot be modified.

If Port header length is 2 bytes, the maximum DLCI number is 1023.

If Port header length is 2 bytes, the restricted DLCIs are 0, 1007, and 1023.

If Port header length is 4 bytes, the restricted DLCIs are 0 and 8257535.

To add Frame Forward connection, the port should be of type Frame Forward.

For Frame Forward port, the maximum connections is 1.

For Frame Relay port, the maximum connections is 4000.

The maximum number of frame relay connections is 16K.

If the connection is in loopback, it cannot be modified.

CIR can only be 0 for uBR connections.

If CIR == 0, BC should also be zero, BE, and zeroCirConEir should be nonzero.

If CIR != 0, BC should be nonzero.

If chanType is Frame Forward, chanFECNconfig should be setEFCIzero, chanCLPtoDEmap should be ignoreCLP, chanDEtoCLPmap should not be mapCLP.

If chanType is NIW or NIWReplacem chanFECNconfig should be setEFCIzero, chanCLPtoDEmap should not be setDEzero or setDEone.

If chanType is frSIW_transparent or frSIW_translate, chanCLPtoDEmap should not be ignoreCLP.

Maximum connections depending on LMI type:

Annex A/D LMI, 2-byte header, FRF 1.2 not enabled: 898 conns

Annex A/D LMI, 2-byte header, FRF 1.2 enabled: 1000 conns (port max)

Annex A/D LMI, 4-byte header, FRF 1.2 not enabled: 640 conns

Annex A/D LMI, 4-byte header, FRF 1.2 enabled: 4000 conns (port max)

Strata LMI, 2-byte header, FRF 1.2 not enabled: 560 conns

Strata LMI, 2-byte header, FRF 1.2 enabled: 1000 conns (port max)

Disk Space Maintenance

As the firmware does not audit the disk space usage and remove unused files, the disk space in C: and E: drives should be manually monitored. Any unused saved configuration files, core files and firmware files, and the configuration files of the MGX-RPM-PR-256/512 and MGX-RPM-XF-512 cards should be promptly deleted manually. Following this procedure allows you to avoid shortage of disk space to successfully store event logs, configuration upload files in the C: drive and the configuration of MGX-RPM-PR-256/512 and MGX-RPM-XF-512 cards in the E: drive.

Non-native Controller Front Card and HDD Card

When a nonnative PXM1E or HDD back card is inserted in the standby controller slot, the firmware does not clean up the drives which have free disk space below 30 percent. When the standby controller card comes up, it needs to be verified whether the contents have been cleaned up.

When a nonnative PXM1E or HDD back card is inserted in the standby controller slot, the firmware does not clean up the non-auto configuration files in the E:RPM directory. These non-auto configuration files in the E:RPM directory have to be manually cleaned up after the standby controller card becomes ready.

Due to the checks for nonnative cards, when the controller front or HDD cards are swapped in the same node, the controller card that attempts to come up as active may get reset twice.

When a nonnative HDD card is inserted into the standby controller slot, verify that after the card becomes ready in the standby controller slot, its hard disk contents are deleted and synchronized the relevant files from the Active card.

clrsmcnf Command

For the clear service module configuration feature, if there is a controller card switchover before the clear service module configuration operation is complete, the clrsmcnf command needs to be reissued to ensure that the configuration is completely cleared to avoid any incomplete cleanup.

For the clear service module configuration feature, using the clrsmcnf command may result in discrepancy in the PNNI configuration. For example, some connections may be in the mismatch state.

If the clrsmcnf command is given with the option to clear the software version for the slot as well, then the card will go into the failed state after the operation is complete.

While using the clrsmcnf command, the card in the specified slot is not usable until the operation has successfully completed.

The clrsmcnf command will not work for redundant service modules.

The clrsmcnf command will not work if an upgrade is in progress.

If MGX-RPM-PR-256/512 or MGX-RPM-XF-512 is configured as an LSC (Label Switch Controller), execution of clrsmcnf command on those LSC slots will be rejected, as designed.

The clrsmcnf command does not work if the controller exists for the slot.

APS

For AXSM-B APS, the back card of the active card must be present for APS to function.

The new commands dspadjlnalm and dspadjlnalmcnt are now supported on AXSMB.

Port LED lights on AXSM-E front cards indicate the receive status of physical line connected to it only when the card is in active state. For a standby AXSM-E card, the LEDs always remain green whether the lines are in LOS irrespective of which lines are active (refer to caveat CSCdv68576).

Path and Connection Trace

Path trace is not supported on the control port.

Path trace will not have the accurate information when there is a crankback on the connect path.

Path and connection trace feature in Release 3.0.00 and higher is not compatible with the path and connection trace available with previous releases.

SNTP

The CWM MIB is not supported in Release 3.0.00 and higher.

Priority Routing

Prioritized reroute of SPVCs is not guaranteed, if the SPVCs originate on a signaling port. We might see SPVCs getting routed out-of-order. In-order routing of SPVCs is guaranteed on non-signaling ports.

The MGX-RPM-PR-256/512 does not support configuration of routing priority. All RPM mastered SPVCs will be assigned a routing priority of 8 by the PXM.

The addcon command on VISM does not have support for specifying the routing priority. All the SPVCs added from VISM are assigned a priority of 8. The routing priority can be changed using the cnfpncon command.

Changing the routing priority for DAX connections will not change the priority of the associated pn-cons (SVCs). This is because the SPVCs will not be derouted and rerouted if just the endpoint parameters are changed, and routing priority is an endpoint parameter. Also, because DAX connections are never derouted, even when the UNI port goes down and the rrtcon command is not supported for DAX connections, the routing priority change will never get reflected. The only way for this to get reflected is to use the dncon and upcon commands. Because DAX connections are never derouted, the effect of this limitation is voided.

Priority routing operates in a best effort manner. This is because of the following reasons:

Two in-order RELEASEs can still arrive out-of-order at the Master node, if they take two different paths.

Under congestion scenarios we can expect RELEASEs to be transmitted out-of-order. This is because we do not want to hold up the release of other calls if we are not able to send RELEASEs on one of the interfaces, as it is congested. The calls that we are unable to release could be higher priority calls.

Lower priority SPVCs can be routed ahead of higher priority SPVCs. This can happen if we have attempted several times to route higher priority SPVCs, but failed. To prevent starvation of lower priority SPVCs, we will start to route lower priority SPVCs and we will get to the higher priority SPVCs at a later point in time.

SPVC Interop

NNI SPVC Addendum Version 1.0 is not supported.

PNNI 1.0 Addendum (Soft PVC MIB) is not supported.

Terminating single-ended SPVCs on AUSMs, CESMs, or FRSMs is not supported.

Origination of single-ended spvcs (with -slavepersflag) from AUSMs, FRSMs, CESMs, VISMs and RPMs is not supported.

CC (Continuity Check) is not be available at the slave end of a single-ended SPVC.

Reporting AIS detection to CWM is not be available at the slave end of a single-ended SPVC.

The tstdelay command is not be available at the slave end of a single-ended SPVC on a switch.

The slave end of a single-ended SPVC is not be visible to CWM.

If single-ended SPVCs are originated from switches, they can only be configured via CLI and not from CWM in the current release.

Single-end provisioning will not be supported for DAX connections, because no value addition is seen for interoperability.

SPVC statistics are not available for the slave endpoint of a single-ended SPVC because this endpoint is non-persistent.

When the persistent slave endpoint of an existing SPVC connection is deleted and the master endpoint is allowed to remain, the connection may get established as a single-ended spvc connection. In this case, CWM will show the connection as Incomplete.

Override of SVC connections on a VPI due to an incoming SPVP request for that VPI is not supported. The following override options are alone supported:

spvcoverridesvc

spvcoverridesvp

spvpoverridesvp.

Preferred Route

Upgrading a preferred routing configured connection from any Release 3.0.x will be non-graceful. In a future release, the configuration of the preferred route identifier information for each connection will be supported on the Service Module cards instead of on the PXM controller. During the upgrade, the preferred route identifier information for each connection will be lost and the preferred route identifier needs to be reprovisioned on the Service Module cards. Also, the preferred route table at the PXM controller will be lost. Connections that have already been routed with preferred routing will remain, and there will be no alarms for these connections.

The preferred routes can be specified only within a PNNI single peer group meaning all the nodes in the preferred route lie within the same peer group.

All the nodes in the network should be running Release 3.0.00 software to use the preferred route feature.

All the links specified in the preferred route should be PNNI links.

If a node in the PNNI network changes its PNNI node ID, the old entry in the persistent topology database in all the nodes in the network need to be deleted. If any of the preferred routes in any nodes in the network contains the changed node as one of the hops, the preferred route(s) must be modified using the new table index (in the persistent topology database) allocated for the changed node.

If a node in the PNNI network is deleted via configuration commands from the persistent topology database, if any of the preferred routes configured at that node (where the delete command is executed) contains the deleted node as one of the hops, the preferred route(s) must be deleted/modified manually.

If a node in the PNNI network is removed via physical decommissioning, and if any nodes in the network had some preferred routes that contain the removed node as one of the hops, the preferred route(s) must be deleted/modified manually.

Due to differences in physical port numbering, non-Cisco nodes can only be the terminating nodes in a preferred route.

When a connection is routed on a route other than its preferred route and if the preferred route becomes available, the connection would not be automatically derouted to route back to its preferred route. The user has to deroute/reroute by using configuration commands (optrte, rrtcon, dncon/upcon etc.).

The preferred route configuration is available using only the CLI at the PXM controller. The configuration of the preferred route will be available with the CWM proxy service agent in a future CWM release.

Persistent Topology

In a mixed network of pre-Release 3.0.00 and 3.0.00 or later nodes, only the node name and the node ID will be shown for a pre-Release 3.0.00 node in the topology database. This is because the feature is not present in pre-Release 3.0.00 nodes.

If a peer group is made up of physical nodes with pre-Release 3.0.00 release logical nodes, then the information for the logical node will be stored in the topology database, because there is no way to distinguish between physical nodes and pre-Release 3.0.00 release logical nodes. Logical nodes with Release 3.0.00 or later will not be stored in the topology database.

To delete a node information entry from the topology database, first remove the node itself from the network, either by disconnecting the cables, or downing all the links between that node and the network. Wait for an hour. Then, delete that node from the topology database. This is done because, even if a node is removed from the topology database of all nodes in the peer group, its PTSEs will still be stored in the other nodes until they are flushed from those nodes. This would happen within an hour's time, but it is configurable as a PNNI timer value. If the node is deleted from the topology database within that hour's time, and the node does switchcc/reboot, then it is possible that the node info for that deleted node will be added back into the topology database.

When the node ID of a node is changed, the old node ID is added back into the topology database as a new node entry. In addition, the old node ID will still be stored in the topology database of all the other nodes in the peer group. In order to delete this entry, wait for an hour so that the PTSEs with the old node ID is flushed from the topology database of all the nodes in the peer group, and then delete the information of the old node ID from the topology database.

It is possible that the gateway nodes are not in synchronicity in a peer group, and this could happen in many situations. For example, a gateway node is added in a peer group, then a node is deleted from the peer group, and another gateway node is configured, then the information for the deleted node would not be in the second gateway node. Another example is that a node is deleted from one gateway node, but not in another gateway node.

When you delete a node from the peer group, the node information must be deleted from all the nodes in that PG, even the non-gateway-node nodes. Otherwise, the node information for that deleted node will still be in the non-gateway-node nodes. This could cause inconsistencies later if this node is configured to be a gateway node.

NCDP

FRSM:NO clock sources supported on FRSM. So if the root clock is chosen to be a port on FRSM it will be a bad clock source and we will compute a new root clock source. Ideally, no clock source should be configured on FRSM.

If a clock source goes bad, there is no way to find out if it has become good. If the user wants NCDP to consider that clock source again, the user needs to re-add the clock source.

Suppose a root clock source is configured on NBSM which is in redundant configuration. If a switchover of the NBSM is done there might be loss of clocking for some time.

Currently there is no way for the user to know what is the secondary (second best) clock source in NCDP mode. This might create problems for the user who is trying to delete/modify the partition on the line carrying the secondary best clock source.

Revertive option is not provided in NCDP.

Manual Clocking

AUSM can support only one clock. If a second clock is configured on the same AUSM card AUSM will send a NACK. When the second clock is sent a NACK, no warning or message is given by the CLI. The NAK can only be found out by looking through the logs. The second clock configured on the AUSM will not be reflected in the clocking database.

If the line carrying the primary or the secondary clock source goes in alarm and a switchcc command is used on the switch, the clock configuration for the line in alarm is removed. The clock configuration will also be removed if any card is rebooted when the clocking line is in alarm. This only applies to AXSM and VISMs.

FRSM: NO clock sources supported on FRSM. If a clock source is configured on FRSM it will not be reflected in our database.

When the resetcd command is used on a service module, the primary and secondary (if configured) clock sources are recommitted even though the primary or secondary clock source is not a port on the service module that was reset. Recommitted means that the primary and secondary clock source will get requalified and the node will temporarily latch onto the internal oscillator, After the clock is requalified, the node will lock onto the primary clock source once again.

The clock will not revert if the clock switched due to frequency drift.

AXSM Cards

If ER stamping is used, the rate interval does not provide sufficient accuracy to be completely effective. As a result, when an AXSM card is supporting a PNNI link which is congested with mixed CBR/ABR traffic, cells will be dropped. This condition only occurs when ER stamping is enabled and CI is disabled on an AXSM PNNI link, along with CBR/ABR traffic running so as cause congestion on the link.

It is recommended that the CI/EFCI mechanism be used for rate feedback rather than the ER stamping mechanism, especially if CBR/ABR traffic is expected (refer to caveat CSCdw63829).

Bulk Status Enquiry

Release 3.0.00 and up have a limitation in using the "Bulk Status Enquiry" signaling message with a node running Release 2.1. Bulk Status Enquiry is a proprietary signaling message used to check whether connections across peer nodes are intact. It is triggered automatically upon PXM switchover as well as in other scenarios like SSCOP link establishment. Though Bulk Status Enquiry will not work with Release 2.1 when the peer node is running release 3.0.00 and up, there is an automatic fall back mechanism to standards specific "Normal Status Enquiry" procedure in case the bulk procedure fails. Hence, there should be no loss of functionality as a result of this limitation (refer to caveat CSCea75590).

SSCOP requires that SCR be equal to 126 cells per second and PCR be equal to 2000 cells per second.

Restrictions for Release 3.0.00

AXSM Model B Restrictions

The enableaxsmbaps command is a PXM CLI command required to turn on additional APS features on AXSM/B cards in Releases 3.0.x and up. By issuing this command, the card operating mode becomes AXSM Op B. This command is required only while upgrading configured cards with Release 3.0.x images. If the AXSM/B cards do not have any configuration and are upgraded with Release 3.0.x, then the card operating mode would be made as AXSM Op B and it is not required to issued the enableaxsmbaps command.

The command has the following syntax:

enableaxsmbaps <primary | secondary slot>

The enableaxsmbaps command should be given after the completion of upgrading to Release 3.0.x. The following requirements are needed to change the card operating mode to AXSM Op B:

For redundant cards, both the cards should be AXSM/B cards and the image on both cards should be Release 3.0.x and up.

For non-redundant cards, the card should be an AXSM/B and the image should be Release 3.0.x and up.

Formatting Disks

The hard disks should not be formatted with the Release 3.0.00 backup boot or runtime firmware. The Release 3.0.00 firmware initializes the disks with DOS File System Version 2.0 where as the earlier 2.x releases use DOS File System Version 1.0. As a result, if the hard disks are formatted with Release 3.0.00 firmware, those disks will become unusable in nodes running Release 2.x firmware. Because Release 3.0.00 firmware is backward compatible, it can use hard disks with DOS File System Version 1.0.

Saving Configurations

The C disk drive should not be used for saving multiple older configurations, images, and core dumps. The disk space on this drive is needed to save event logs and configurations, and the logs and configurations will not be correctly saved if there is inadequate disk space.

Other Limitations and Restrictions

PXM disk sync verification will not work if an upgrade is in progress.

The maximum number of connections supported in Release 3.0.00 is 250K connections with the PXM45/B controller cards.

Load sharing will not be enabled automatically if upgrading from a lower revision that has load sharing disabled.

Path and connection trace are not supported between different peer groups.

On AXSM cards, when configuring virtual interfaces (i.e. VUNI, VNNI, EVUNI, EVNNI), the physical interface must be of all one ATM header type, either UNI or NNI. Keep in mind that the signaling that is applied to a virtual port is independent of the actual virtual port ATM header. The only limit will be that the VPI value must be within the UNI ATM header limitations (0-255).

Clearing the Configuration on Redundant PXM45 and PXM1E Cards

Due to checks to prevent an inserted card from affecting the system, an additional step may be required when inserting two nonnative PXM45 (or PXM1E) cards in a shelf. Insert the first PXM45, use the clrallcnf command, and allow this to become active before inserting the second PXM45 (or PXM1E).

After using the clrallcnf command, you must clean up old SCT files (refer to caveat CSCdw80282).

Limitations and Restrictions for 2.1.x

This section is extracted from the MGX 2.1.79 release notes. It describes the following issues for Releases 2.1.60 through 2.1.80:

General limitations, restrictions, and notes

APS management information and open issues

Clearing the configuration on redundant PXM45/B cards

General Limitations, Restrictions, and Notes

The following limitations and restrictions apply to this release.


Note For the MGX 8950, references to "AXSM" refer to the AXSM/B cards.


The 8 port MMF back cards for the AXSM and AXSM/B front cards do not support Y-cable redundancy.

Presently, the PXM CLI allows for provisioning of a PNNI controller (controller id 2) on any slot in the chassis, but for this release, such provisioning should be restricted to slot 7 only.

The maximum number of logical interfaces (physical trunks, virtual trunks, logical ports) supported in this release with the PXM45 card is 99, and for PXM45/B cards it is 192. Of the 192 PNNI interfaces, up to 100 interfaces can be signaling ports. The other 92 interfaces should be non-signaling ports, such as non self-supporting ports.

AXSM-1-2488 and AXSM-1-2488/B cards do not have a policing function enabled.

The front card hardware (motherboard/daughterboard) for each card type can support up to two back cards. But in Release 2.1.80, only one AXSM-E back card (that is, half the port capacity available in hardware) is supported by software. The full port capacity will be supported with a future software release. No hardware changes will be required.

In Multiple Peer Group (MPG) mode, when one switches over to the standby on a PGL node with three levels, it can take several minutes on the standby card for this PGL to come up and the SVC based RCC to setup. This is normal behavior, because PNNI does not support hot redundancy. For a switchover, the entire PNNI database must be rebuilt. (It is like a reboot for PNNI, even though the active calls are not affected.)

Trace information captured in the error logs of non-PXM slots (seen with the dsperr -sl <slotnum> command) will not translate addresses in the trace to correct symbolic names. Such files with trace data need to be moved off the system using FTP and forwarded to TAC and engineering.

Support for three controllers only (one for PNNI and two for LSC). Controller ID 2 is reserved for a PNNI controller; IDs 3 to 20 are available for LSC controllers.

Partition ID 1 is reserved for PNNI.

The maximum number of logical interfaces (physical trunks, virtual trunks, logical ports) supported in this release with PXM45 cards is 99 and PXM45/B cards is 192.

If an active AXSM card is stuck in the active INIT state, the standby PXM will not go to the standby ready state until the active AXSM goes to a steady state. The steady states are: active ready, failed, mismatch, empty, empty reserved, and standby ready. With redundancy configured, if a standby AXSM card is stuck in a standby init state, with an active AXSM already in a active ready state, the standby PXM will go to the standby ready state without delay. If both AXSMs in the redundancy pair are not in a steady state, then the standby PXM will not go to the standby ready state until one or both of the two AXSM cards are in the active ready state.

If the destination address is reachable for both an IISP and a PNNI link from the same node, ABR connections will not route. The current routing algorithm will always choose IISP links over PNNI links because it is local. Because IISP does not support ABR connections, the connection setup will fail.

In this release, a Service Class Template (SCT) can be changed with connections present. However, if the change affects services in use, the connections will be rerouted.

When CWM is used to manage the network, the IP address 10.0.x.x cannot be used as the LAN address (lnPci) for the switch.

Caveat CSCdx29956 information—the release note enclosure contains these fields:

Symptom: Cellbus clock configuration defaults after a power cycle.

Condition: Set one of the cell bus clock speeds to 42 MHz and power cycle the node.

Workaround: Re-configure cell bus clock after a node rebuild.

If there are MGX-RPM-PR-256/512 card(s) in the node, after clrallcnf, the standby controller card takes longer to come up. The more MGX-RPM-PR-256/512 cards in the node, the longer the standby controller takes to come up. This also happens when the standby controller card is coming up, and MGX-RPM-PR-256/512 cards are inserted into slots that were not previously used for MGX-RPM-PR-256/512 cards.

Limitations for rteopt via Parallel Links

This section lists limitations for rteopt via parallel link. Use Figure 1 as you work through the scenarios in this section.

Figure 1 Configuration Example for rteopt via Parallel Link

The configuration for Figure 1 and the scenarios in this section are as follows:

Link 1 has forward and backward admin weight set to 500 (via cnfpnni-intf).

Link 2 has forward and backward admin weight set to 1000.

Link 3 has forward and backward admin weight set to 2000.

SPVC connection is routed from Node A to Node C (Master endpoint is at Node A) via link 1 and link 2.

Scenario 1: Link 2 is down (for example, by using the dnpnport command), connections are rerouted right away but Node A has not had that information updated in the routing tables yet.

SPVC on Node A will have routing cost = 2*500 + 2*1000 = 3000, but since link 2 is down, Node B will choose link 3. The routing cost on Node A SPVC is still 3000 as it did the calculation during the route search.

If link 2 is up, if you use a rteopt command on Node A to obtain the new route, and the new path selected has a cost of 3000.

Because SPVC has 3000, it does not reroute through link 2.

Scenario 2: Instead of link 2 being down, if there is a crankback on link 2, the same result stated above occurs.

Scenario 3 (for CBR and VBR): Link selection is set as maxavcr, maxcr, or random on Node B (by using the cnfpnni -selection command) If link 2 has less bandwidth than link 3, and the link selection criteria at Node B is set to maxavcr, Node A will still put the cost as 3000 with least aw calculation, but Node B will choose link 3 (even though it is costlier) because it has more bandwidth.

Scenario 4 (for ABR and UBR): Link selection does not apply to ABR and UBR (by using the cnfpnni -selection command). This is exactly the same as Scenario 3 because ABR and UBR follow load balancing on parallel links instead of choosing the minaw link.

Scenario 5 (for all types of service categories): After call setup, if the admin weight is increased on the link on which the call is routed, the routing cost calculated during the call setup will not get changed. So if a rteopt is done after increasing admin weights on the existing links on the connection path, the connections will not get optimized to take the newer path.

Workaround

If you use the dnpnport command on link 2 (connections will be routed via link 3), after using the uppnport command on link 2, then use the cnfpnni-intf command to change the existing administrative weight on link 2 to a lesser value, for example, 800 (from 1000).

When the optrte command is used at Node A, routing cost will be = 2*500 + 800(fwd) + 1000 (bwd) = 2800 for the new route of link 2.

Because all SPVC connections have 3000 as the routing cost, connections will be rerouted on link 2.

Important Notes

This section provides general notes that apply to this release, and covers some procedures that are not yet in the manuals.

You must use the SCT files released with Version 2.1.80 (number 2 and 3, which were included in Version 2.0.13 are similar to number 2 and 3 for 2.1.80) for the Control VC feature. If you are using the MPLS feature, then you will need to change to SCT 4 or 5, which were released with Version 2.1.00.

By default, 2000 cps and 543 cps will be reserved for SSCOP and PNNI Signalling VC respectively, even when you disable SSCOP and PNNI. These values are configurable by the cnfpnctlvc command.

Do not execute the delcontroller command when connections/ports still exist. The impact of executing delcontroller with connections is that the connections cannot be recovered until the controller is re-added using addcontroller and the AXSM cards or the entire node has to be reset (otherwise ports remain in the provisioning state). There is now a warning to the user of the impact of the command when there are existing connections/ports.

Analysis of the code has identified a situation which has a low probability of occurring and in fact has not been encountered in any test scenarios to date. This caution and associated workaround is provided as a precautionary measure. When the link bandwidth for SPVC connections is reaching full capacity, making minimal bandwidth available for new SPVC connections, a condition can be encountered where the initial software check believes there is sufficient bandwidth for the new SPVC connection. However, the final software confirmation for available bandwidth may be rejected because there is no bandwidth available. If this problem occurs, the system will recover when the PNNI updates are refreshed. (This will happen at the default time of 30 minutes.) The user can recover from this problem by making the Administrative weight of that link very high to avoid that link from being used.

When the switch cannot automatically resolve nativity check conflicts, you can force a configuration rebuild from a specific hard disk by establishing a console port session through the corresponding PXM-UI-S3 card and issuing the shmRecoverIgRbldDisk command. This command ignores the nativity check and configures the entire switch according to the configuration on the hard disk.

PNNI default minimum VCI is 35 unless changed explicitly. The reason for the default is to reserve VCI=32-34 for other control purposes (for example, MPLS and NCDP). For users who would like to add MPLS controller in future releases of MGX 8850, it is highly recommend to set the min-vci value to be 35 or more for all partitions on the port where the MPLS partition will be added. By doing so, the TDP sig vc for MPLS will be established automatically on 0/32. Minimum VPI is not negotiated by ILMI, so the user should set this parameter the same on both nodes.

APS Management Information

The following tips apply to the use of the dspapsbkplane command and the APS connector, which is sometimes called a backplane. The APS connector must be installed to enable intercard APS.

The APS dspapsln, dspapslns, switchapsln, and dspapsbkplane commands were modified in release 2.1.70.


Note The dspadjlnalm and dspadjlnalmcnt commands are new to Release 3.0.00. The dspadjlnalmcnt command is supported on AXSM-E and AXSM/B.


The APS dspadjlnalm command was new to release 2.1.70. Refer to the Release Notes for MGX 8850 Command Reference for Release 2.1 at the following location for further details about the commands mentioned in these release notes:

http://www.cisco.com/univercd/cc/td/doc/product/wanbu/8850r21/index.htm


Note The issues in this section are seen only in Operational mode 1+1, bidirectional, Rev/non-Rev. If at least one side is configured as 1+1 unidirectional, these problems do not occur.


The following are some open issues in this release:

Reset of active AXSM/A or AXSM/B, removal of active AXSM/A or AXSM/B, or AXSM/A or AXSM/B card switchover may cause the lines behind that card to be in an LOS status for 20ms to 30ms. If these lines were active at the time, some additional APS switch will occur; and the corresponding lines at the far-end will be in SF alarms before the standby AXSM card comes up. The momentary loss of signal is due to the hardware limitation; no other workaround is available. (Refer to caveat CSCdu41763—P-comment and CSCdv01058—Eng-Note for more details.)

For AXSM/A hardware only: If multiple active lines are removed at the same time, one line may not switch over.

To recover, either perform a lockout of Protection line and Clear from the far end or perform delete APS for the line, then add the APS line back.

Preparing for Intercard APS

The following components are required for intercard APS:

Two front cards.

Two back cards for every bay hosting APS lines. All lines on cards used for intercard APS must operate in APS pairs or use Y cables.

An APS connector installed between the two back cards for every bay hosting APS lines.

Use the dspapsbkplane command on both the standby and active card to verify that the APS connector is plugged in properly. The following example shows the results displayed by the dspapsbkplane command when the APS connector is in place:

M8xx0_NY.1.AXSM.a > dspapsbkplane

Line-ID   Primary Card Signal Status       Secondary Card Signal Status

  2.1               PRESENT                             ABSENT 
  2.2               PRESENT                             ABSENT 

Remote Front Card : PRESENT 
Top Back Card     : ENGAGED 
Bottom Back Card  : ENGAGED 

The following example shows the results displayed by the dspapsbkplane command when the APS connector is not place:

M8xx0_LA.1.AXSM.a > dspapsbkplane

Line-ID   Primary Card Signal Status       Secondary Card Signal Status
                    Slot #1                             Slot #2        
  1.1               PRESENT                             ABSENT
  1.2               ABSENT                              ABSENT 
  2.1               PRESENT                             ABSENT 
  2.2               ABSENT                              ABSENT 

Remote Front Card : ABSENT 
Top Back Card     : ENGAGED 
Bottom Back Card  : NOT-ENGAGED 

Note The dspapsbkplane command should be used only when the standby card is in the Ready state. When the standby card is booting or fails, intercard APS cannot work properly and this command displays NOT ENGAGED.


If the dspapsbkplane command displays the APS Line Pair does not exist message, suspect that the APS is not configured on a line.

If the dspapsbkplane command shows different values for each of the two cards, suspect that the APS connector is seated properly on one card but not on the other.

The APS connector status is the same for all lines in a single bay because the APS connector interconnects two back cards within the same bay. You need to enter the dspapsbkplane command only once to display the APS connector status for both upper and lower bays.

Enter the dspapslns command to verify APS configuration. If the working and protection lines show OK, both lines are receiving signals from the remote note.

Managing Intercard APS Lines

In AXSM and AXSM/B intercard APS, either front card can be active, and can be connected to either APS line through the APS connector joining the two back cards. The following process describes how intercard APS communication works:

1. The signal leaves the front card at the remote end of the line. (See Figure 2 and Figure 3.)

2. The signal passes through the APS connector and both back card transmit ports at the remote end of the line. (See Figure 2 and Figure 3.)

3. The signal travels through both communication lines to the receive ports on both back cards at the local end. (See Figure 2 and Figure 3.)

4. The active front card processes the signal that is received on the active line. (See Figure 2 and Figure 3.)

5. The standby card monitors only the status of the standby line. (See Figure 2 and Figure 3.)

6. If necessary, the signal passes through the APS connector to the front card. (See Figure 3.)


Note For AXSM, the front card monitors only one of the receive lines. For AXSM/B, the front card monitors both the receive lines.


Figure 2 shows an example of how this process operates in a standard APS configuration, where the primary card monitors the working line and the secondary card monitors the protection line.

Figure 2 Standard APS Configuration

Figure 3 shows an example of how the APS communication process operates in a crossed APS configuration, where the secondary card monitors the working line that is attached to the primary card, and the primary card monitors the protection line that is connected to the secondary card.

Figure 3 Crossed APS Configuration

Line failures are always detected at the receive end of the line. This is where a switchover occurs when a failure is detected. Two different types of switchovers can occur, depending on whether the APS was configured as unidirectional or bidirectional in the cnfapsln command:

When a failure occurs on a line configured for unidirectional switching, the switch changes lines at the receive end only. A switchover is not necessary at the transmit end because the transmitting back cards send signals on both lines in the 1 +1 APS configuration.

When a failure occurs on a line configured for bidirectional switching, a switchover occurs at both ends of the line.

If the status of the standby line is good, a switchover from the failed active line to the standby is automatic.

Enter the cnfapsln command to enable an automatic switchover back to the working line after it recovers from a failure, as shown in the following example:

M8xx0_LA.1.AXSM.a > cnfapsln -w 1.1.1 -rv 2

Slot number, bay number, and line number of the active line to configure, in the format:

slot.bay.line

Example: -w 1.1.1

-sf <signal fault ber>

A number between 3 and 5 indicating the Signal Fault Bit Error Rate (BER), in powers of 10:

3 = 10-3

4 = 10-4

5 = 10-5

Example: -sf 3

-sd <SignalDegradeBER>

A power if 10 in the range 5 to 9 that indicates the Signal Degrade Bit Error Rate (BER):

5 = 10-5

6 = 10-6

7 = 10-7

8 = 10-8

9 = 10-9

Example: -sd 5

-wtr <Wait To Restore>

The number of minutes to wait after the failed working line has recovered, before switching back to the working line. The range is 5 to 12.

Example: -wtr 5

-dr <direction>

Determines whether the line is unidirectional or bidirectional.

1 = Unidirectional. The line switch occurs at the receive end of the line.

2 = Bidirectional. The line switch occurs at both ends of the line.

Note This optional parameter is not shown in the above example because you do not need to set it for a revertive line.

Example: -dr 2

-rv <revertive>

Determines whether the line is revertive or non-revertive.

1 = Non-revertive. You must manually switch back to a recovered working line.

2 = Revertive. APS automatically switches back to a recovered working line after the number of minutes set in the -wtr parameter.

Example: -rv 1


If you want to manually switch from one line to another, enter the switchapsln <bay> <line> <switchOption> <service switch> command, as shown in the following example:

M8xx0_LA.1.AXSM.a > switchapsln 1 1 6
Manual line switch from protection to working succeeded on line 1.1.1

Table 20 describes the configurable parameters for the cnfapsln command.

Table 20 The switchapsln Command Parameters 

Parameter
Description

bay

The working bay number to switch.

line

The working line number to switch.

switchOption

The method of performing the switchover.

1 = Clear previous user switchover requests. Return to working line only if the mode is revertive.

2 = Lockout of protection. Prevents specified APS pair from being switched over to the protection line. If the protection line is already active, the switchover is made back to the working line.

3 = Forced working to protection line switchover. If the working line is active, the switchover is made to the protection line unless the protection line is locked out or in the SF condition, or if a forced switchover is already in effect.

4 = Forced protection to working line switchover. If the protection line is active, the switch is made to the working line unless a request of equal or higher priority is in effect. This option has the same priority as option 3 (forced working to protection line switchover). Therefore, if a forced working to protection line switchover is in effect, it must be cleared before this option (forced protection to working line switchover) can succeed.

5 = Manual switchover from working to protection line unless a request of equal or higher priority is in effect.

6 = Manual switchover from protection to working line. This option is only available in the 1+1 APS architecture.

service switch

This is an optional parameter. When set to 1, this field causes all APS lines to switch to their protected lines.


Enter the dspapslns command to verify that the active line switched over from the protection line to the working line, as shown in the following example:

M8xx0_LA.1.AXSM.a > dspapslns
Working Prot.  Conf  Oper    Active  WLine PLine WTR   Revt Conf Oper LastUser
Index   Index  Arch  Arch    Line    State State (min)      Dir  Dir  SwitchReq

Troubleshooting APS Lines

This section describes the port light behavior changed in Release 3.0.00 as follows:

Port lights on AXSM /B front cards indicate the receive status of APS lines.

The active front card always displays the status of the active line.

The standby card always displays the status of the inactive line. If only one APS line fails, the line failure LED is always displayed on the standby front card.

Port lights on AXSMB front cards indicate the receive status of the physical line connected to it. For example, when APS is configured for working line as 5.1.3 and protection line as 6.1.3, regardless of which card is active, the port LED on card 5 will show the receive status of 5.1.3 and card 6 will show the receive status of 6.1.3.


Note The remainder of this section is the same as for Release 2.1.80 unless otherwise noted as updated for Release 3.0.10.



Caution When the active front card and the active line are in different slots and the inactive line has failed, it is easy to incorrectly identify the failed line as the line in the standby slot. To avoid disrupting traffic through the active line, verify which physical line is at fault before disconnecting the suspect line.

If the active line fails and the standby line is not available, the switch reports a critical alarm.

If the active line fails and the standby line takes over, the former standby line becomes the new active line, and the switch reports a major alarm.

If an AXSM/A front card fails, APS communication between the redundant front cards fails. This can result in one of the following situations:

If both APS lines were working before the failure, an APS line failure causes a switchover to the protection line.

If either APS line failed prior to a front card failure, a failure on the active line does not cause a switchover to the other line. Because the standby front card failed, it cannot monitor the standby line and report when the line has recovered. This means that the active card cannot use the standby line until the standby front card is replaced and the line problem corrected.

Use the following procedure to troubleshoot APS lines:


Step 1 Enter the dsplns command to determine if the line in alarm is an APS line. The dsplns  command shows which lines are enabled for APS:

M8xx0_LA.1.AXSM.a > dsplns
                                           Medium Medium 
  Sonet  Line     Line     Line    Frame   Line   Line     Alarm   APS 
  Line  State     Type     Lpbk   Scramble Coding Type     State   Enabled
  ----- ----- ------------ ------ -------- ------ -------  -----   -------- 
   1.1     Up sonetSts12c NoLoop   Enable  Other ShortSMF    Clear Enable
   1.2     Up sonetSts12c NoLoop   Enable  Other ShortSMF    Clear Disable
   2.1     Up sonetSts12c NoLoop   Enable  Other ShortSMF    Clear Disable
   2.2     Up sonetSts12c NoLoop   Enable  Other ShortSMF    Clear Disable

If the line in alarm is an APS line, and has always functioned properly as an APS line, proceed to Step 2.

If the line in alarm has never functioned properly as an APS line, verify that the following are true:

Redundant front and back cards are in the appropriate bays and are installed at both ends of the line.

Cable is properly connected to both ends of the line.

Enter the dspapsbkplane command to verify that the APS connector is installed properly at both ends of the line.

Step 2 Enter the dspapslns command at both ends of the communication line to determine whether one or both lines in an APS pair are bad. Use Table 21 to help you determine which APS line is not functioning properly.


Note Table 21 is updated for Release 3.0.00.

If one or both lines appear to be bad, determine whether the working or protection line is in alarm. Troubleshoot and correct the standby line first. Replace the components along the signal path until the problem is resolved.

If the dspapslns command at either end of the line indicates a front or back card problem, resolve that problem first. (See Table 22 to troubleshoot card problems).

If the dspapslns command shows a signal failure on the standby line, replace that line.

If the standby line is still down, replace the cards along the signal path.

Installing and Upgrading to Release 3.0.25

For upgrades, the term graceful means the process does not interrupt switch traffic or change the switch configuration.

The MGX 8850 (PXM45) switch can be gracefully upgraded to Release 3.0.25 from Release 2.0.15, 2.0.16, 2.1.81 and 3.0.23. If upgrading from a release lower than 2.0.15, then the node must be upgraded first to 2.0.15, then to 3.0.25.

The MGX 8850 (PXM1E) and MGX 8830 switch can be gracefully upgraded to Release 3.0.25 from Release 3.0.23.


Note MGX Release 3.0.25 was not tested for the MGX 8950 switch.



Note Starting with Release 3.0.10, CLI commands and shellconn commands can be used to burn the boot images.


Important Upgrade Notes


Note If there are already two database versions on the disk, there may not be enough space for a new database to be created. Please read the Release-note enclosure for CSCdz29983. This Release-note enclosure is described in the "MGX 8830 and MGX 8850 (PXM45/PXM1E) Open Caveats in Release 3.0.25" section.


Frame Discard


Note An important caveat exists for virtual path connections (VPCs) that were added with frame discard enabled before version 3.0.23 or 4.0.10. The switch lets you enable frame discard on a VPC, even though hardware does not support it. If a VPC with frame discard enabled already existed on the node when you upgrade to release 3.0.23, 4.0.10, or later, you cannot subsequently modify the VPC unless you delete it, then re-add it with frame discard disabled. To avoid the need to delete a VPC, disable frame discard on any such VPCs before you upgrade to MGX releases 3.0.23, 4.0.10, or later.


The order of software releases was as follows:

MGX 4.0.00 April 2003

MGX 3.0.23 May 2003

MGX 4.0.10 August 2003

MGX 4.0.11 October 2003

MGX 4.0.12 October 2003

MGX 3.0.25 December 2003

AXSM/B Cards Running APS

On upgrading to 3.0.10 and higher, the cnfxbarmgmt command has to be issued in the following cases to enable the loadsharing and auto shutdown when it is not enabled by default during the upgrade:

A non-graceful upgrade from 2.0.x to 3.0.10 and higher.

Upgrading from 2.1.76 or later when load sharing or auto shutdown is manually disabled.

AXSM Cards in Op B Mode and APS Lines

If the firmware is being upgraded using loadrev/runrev to Release 3.0.10 and higher from Release 3.0.00, the APS lines must be deleted prior to the upgrade if all of the following conditions are met (refer to caveat CSCdy09317).

APS is operating in the Operating Mode B. This can be verified from the output of the dspcd command on the AXSM card.

APS lines have been added and none of the APS lines are configured with ITU-T protocol (that is, Annex-B protocol).

When upgrading from 2.1.80 to 3.0.10 and higher, check that the working and protection lines are free of any line failures prior to issuing the enableaxsmbaps command. Otherwise, the ports can go down. If this problem is encountered, take out the receive part of the line that doesn't have the alarm and re-insert it (refer to caveat CSCdz50925).

NNI Ports

Signaling must be configured on NNI ports prior to upgrading to Release 3.0.00 and higher. Otherwise, for an NNI port with no signaling and ILMI enabled, after upgrading to Release 3.0.00 and higher, the PNNI link will go down.

Manual Clocking

Manual clocking may latch twice when upgrading the PXM45 controller cards from Release 2.1.x to Release 3.0.00 and higher.

Upgrade Precautions from 2.0.x

For 1+1 APS and while the standby card is resetting during the upgrade process, the far end APS status is invalid and dspapsln will show the line is in mismatch or SF state (the NNI link will stay up). Once the standby card comes up, alarm will be clear. This means that APS protection is lost during the standby card reset.

The ILMI default value for Release 2.0.15 is 0 for UNI and NNI ports, but Release 3.0.10 and higher uses the minVPI defined in the partition.

Installation and Upgrade Procedures

The procedures to upgrade to Release 3.0.25 appear in "Appendix A, Downloading and Installing Software Upgrades" in:

CSCdz29610

Symptom: IMA link is stuck in LODS alarm.

Conditions: Both 1 & 2 need to be met. 1. When only the Rx of IMA link at one end is disconnected and re-connected. 2. The link whose Rx is disconnected is cross-connected at the other end.

Workaround: 1. Delete the link and add it back. OR 2. Restart the group using CLI restartimagrp.

Hardware: PXM1E-IMA

CSCdz31938

Symptom: Current core shows 2 or 3 instead of valid values 0 or 1.

condition: Seems to only happen in version 3.0.11.0 On CLI, on executing 'core', the display shows current core as 2 or 3.

Workaround: On the CLI, execute command 'core clear'. This will take care of the problem for good.

Hardware: PXM1E

CSCdz43030

Symptom: IMA link added to a group displays the following Rx & Tx states and does not become active even if it is connected to the FE link and there are no line alarms. X,Y,A and Z are any valid numbers. dspimalnks =========== Link Grp Rel Ne Ne NeRx Tx Rx Num Num Dly Tx Rx Fail Lid Lid (ms) State State Status ------------------------------------------------------------------------------ 1.X 1.Y 0 Not in Group Not in Group No Failure Z A

Conditions: Current state: The group has non-zero links in LIF failure that are not connected to FE. Action that leads to the above problem: The group is restarted using CLI restartimagrp or corresponding SNMP command. After the restart, any link addition will result in the state mentioned above.

Workaround: 1. Connect all links to FE and make sure there are no physical line alarms on any of the links and that the FE group is sending valid ICP cells on all the links. All the links will then transition to active by themselves. OR 2. Delete all links from the group and add them back. In this case, the links that are connected to FE will become active.

Hardware: AXSME-IMA

CSCdz46545

Symptom: Clock source stuck in wideband-locking

The card is restored after about 2 minutes. This can happen a few times a day with periods of nearly a month with no problems. Card replacement already performed.

Conditions: Normal operation for the switch.

Workaround: None.

Hardware: AXSM-16-155

CSCea64790

Symptom: AXSM in Yred 1:1 configuration has a strange behavior: standby card fails and goes into the Init/Boot/Empty status, traffic on the active card is affected, a reset on the failed card affects the active card too. The active card is not accessible via CC command, reply: "Err: redirection timed out"

Conditions: System running code 3.0.20; Yred configuration on AXSM 1:1.

Workaround: Resetting via CLI on the "ACTIVE" card, it will restore both the cards but some ghost connections may appear in "mismatch" status. Need to delete the connections manually. A display of those connections will display the following message: "ERR: Connection does not exist on controller".

Hardware: AXSM

CSCea78828

CSCdx62800

Symptoms: MGX45 CLI Reference Manual needs to be updated.

Conditions: 4 new commands missing out of the manual.

Workaround: None.

Hardware: PXM45B

CSCdx82847

Symptom: Line status LED's on standby PXM1E always show green.

Conditions: The line status LED on a standby PXM1E is always green even if the line is in LOS. This is inconsistent with other LEDs on the PXM1E. e.g. the ALARMs LEDs on the standby PXM1E remain OFF. We think that the line status LED should either reflect same as the active PXM1E or they remain OFF as of the alarm LED.

Workaround: None.

Hardware: PXM1E

CSCdx85715

Symptom: CLI needed to display config and connection type of svc based RCC.

Conditions: Command equivalent to dsppnctlvc.

Workaround: None.

Hardware: PXM45B

CSCdy23797

Symptom: pntrace commands not completely documented.

Conditions: MGX CLI Manual vs. the troubleshooting guide.

Workaround: None.

Hardware: PXM45B

Symptom: Need warning messages for cnfport

Conditions: Warning messages are needed to inform the user that cnfport is going to be changed.

Workaround: None.

Hardware: PXM1E

CSCdy37182

Symptom: dspcd shows lower back card empty for a full height back card.

Conditions: None.

Workaround: None. Not service impacting, only a display issue.

Hardware: all

CSCdy41895

Symptoms: 'dspportsct vcThr' should match with the one shows on 'dspportsct qeVcThr' But the VSI_Signal values shown from SCT does not match to the actual HW value.

Conditions: dspportsct vcThr & dspportsct qeVcThr.

Workaround: This is a display problem. The VSI_Signal VC Threshold values being display from the dspportsct or dspcdsct command is incorrect. Basically the AXSME software ignores the VC Threshold values being specified in SCT. Instead, the AXSME software would program a lower pre-defined threshold values for the VSI Signal channels. So the values in the HW are correct. Please ignore the VSI_signal values from the SCT. The lower pre-defined is needed because we want to limit our traffic flow on the VSI signaling channels prevent flooding the PXM45. If the PXM45 is flooded, then there will be some unpredictable and unreliable behaviors on PXM45. We are going to fix the display problem.

Hardware: AXSME

CSCdy47415

Symptom: delred shows incorrect error message.

Conditions: delred command issued.

Workaround: No workaround needed. Just ignore the message and use dspred to verify the delred result.

Hardware: PXM1E

CSCdy49757

Symptom: AUSM channel, port and SAR counters do not correctly count RM cells received from CPE.

Conditions: The AUSM channel, port and SAR counters do not correctly handle RM cells when they are generated by the CPE (test-set). When RM cells are received by the AUSM card the baseline behavior is that they should be discarded by the UNI port. Indeed that is what is noted to happen for AUSM on PXM1E. The command dspconload" shows that no traffic is received from the AUSM when a stream of RM cells at 480 cps is generated by the test-set.

Workaround: None.

Hardware: AUSM-8T1E1

CSCdy59294

Symptom: AUSM/PXM1E transmits invalid PTI=7 cells into network but cannot pass traffic out of far-end AUSM port.

Condition: An abr1 PVC was provisioned between two AUSM-IMA ports: [Test Set A] <---> node1 to node2 <---> [Test Set B] Test set A generated 480 CPS of ATM cells with the PTI field set to 7 (invalid). The payload consisted of 48 byte 6A pattern. The channel, port and SAR counters on node1 indicate that traffic is being sent into the network. On the PXM1E card on node1 the "dspconload" command indicates that all the PTI=7 traffic is sent out the trunk interface. In fact there seems to be RM cell overhead in both directions. The "dspconload" command on node1 indicates that all PTI=7 traffic is being received on the trunk interface. However on the AUSM port on node2 the chan, port and SAR counters all remain at zero. It is very strange that the AUSM card handles PTI=7 cells differently on the Ingress and Egress directions. At one time the PVC was able to transmit PTI=7 cells end to end but it has only been observed to happen once.

Workaround: None.

Hardware: AUSM-8T1E1

CSCeb72485

Symptom: The CESM port will get stuck in RcvAIS due to an alarm loop.

Conditions: This should be specific to a hard loopback or to equipment that transmits back exactly the same T1 state as received (without interpretation). With a test set or any equipment on one end of a CESM connection and a loopback on the remote end when there is an ATM PVC failure, there is an alarm loop which prevents the circuit from coming up even after the ATM PVC is restored.

Workaround: Once in this state, to recover the line alarm must be cleared. This can be accomplished by plugging in a good T1 or by resetting the CESM.

Hardware: CESM-8T1E1

Conditions: Normal operation for the switch.

Workaround: None.

Hardware: AXSM-16-155

CSCea64790

Symptom: AXSM in Yred 1:1 configuration has a strange behavior: standby card fails and goes into the Init/Boot/Empty status, traffic on the active card is affected, a reset on the failed card affects the active card too. The active card is not accessible via CC command, reply: "Err: redirection timed out"

Conditions: System running code 3.0.20; Yred configuration on AXSM 1:1.

Workaround: Resetting via CLI on the "ACTIVE" card, it will restore both the cards but some ghost connections may appear in "mismatch" status. Need to delete the connections manually. A display of those connections will display the following message: "ERR: Connection does not exist on controller".

Hardware: AXSM

CSCea78828

Symptom: Both PXM45B failed after loadrev latest test image, and the log reports fatal error on slot8.

CSCdy41895

Symptoms: 'dspportsct vcThr' should match with the one shows on 'dspportsct qeVcThr' But the VSI_Signal values shown from SCT does not match to the actual HW value.

Conditions: dspportsct vcThr & dspportsct qeVcThr.

Workaround: This is a display problem. The VSI_Signal VC Threshold values being display from the dspportsct or dspcdsct command is incorrect. Basically the AXSME software ignores the VC Threshold values being specified in SCT. Instead, the AXSME software would program a lower pre-defined threshold values for the VSI Signal channels. So the values in the HW are correct. Please ignore the VSI_signal values from the SCT. The lower pre-defined is needed because we want to limit our traffic flow on the VSI signaling channels prevent flooding the PXM45. If the PXM45 is flooded, then there will be some unpredictable and unreliable behaviors on PXM45. We are going to fix the display problem.

Hardware: AXSME

CSCdy47415

Symptom: delred shows incorrect error message.

Conditions: delred command issued.

Workaround: No workaround needed. Just ignore the message and use dspred to verify the delred result.

Hardware: PXM1E

CSCdy49757

Symptom: AUSM channel, port and SAR counters do not correctly count RM cells received from CPE.

Conditions: The AUSM channel, port and SAR counters do not correctly handle RM cells when they are generated by the CPE (test-set). When RM cells are received by the AUSM card the baseline behavior is that they should be discarded by the UNI port. Indeed that is what is noted to happen for AUSM on PXM1E. The command dspconload" shows that no traffic is received from the AUSM when a stream of RM cells at 480 cps is generated by the test-set.

Workaround: None.

Hardware: AUSM-8T1E1

CSCdy59294

Symptom: AUSM/PXM1E transmits invalid PTI=7 cells into network but cannot pass traffic out of far-end AUSM port.

Condition: An abr1 PVC was provisioned between two AUSM-IMA ports: [Test Set A] <---> node1 to node2 <---> [Test Set B] Test set A generated 480 CPS of ATM cells with the PTI field set to 7 (invalid). The payload consisted of 48 byte 6A pattern. The channel, port and SAR counters on node1 indicate that traffic is being sent into the network. On the PXM1E card on node1 the "dspconload" command indicates that all the PTI=7 traffic is sent out the trunk interface. In fact there seems to be RM cell overhead in both directions. The "dspconload" command on node1 indicates that all PTI=7 traffic is being received on the trunk interface. However on the AUSM port on node2 the chan, port and SAR counters all remain at zero. It is very strange that the AUSM card handles PTI=7 cells differently on the Ingress and Egress directions. At one time the PVC was able to transmit PTI=7 cells end to end but it has only been observed to happen once.

Workaround: None.

Hardware: AUSM-8T1E1

CSCdz29983

Symptom: Standby card might not come up after the loadrev.

Condition: SES node's disk space is not enough for the new database to be created if there

are already two dbVersions in the disk.

Workaround: Remove old database before the upgrade.

To remove, first check if there is more than the current database

- Save the current configuration: CLI "saveallcnf"

- If more than the current DB Version has been created, then take action

to remove other/old database following these steps:

0- From the Active PXM slot, "dspversion" to know the current FW version.

1- From the Active PXM slot, "cd D:/DB2/LS1"

2- "ls" to see if there is any extra DB Version beside the current

expected version DB. The extra DB Version should be deleted.

3- go to shellconn and still in "D:/DB2/LS1" directory path.

4- Delete the extra database: pxm1> "deltree VER00X_YYY_ZZZ"

5- Do steps from 1 to 4 to check and remove any extra database on the

Standby PXM1 also.

Symptom: Loss of activity and clock switching to priority 1 messages observed in event log.

Condition: AXSM-OC48 cards in system were being reseated.

Workaround: Unknown.

Hardware: PXM45

CSCdu26141

Symptom: SHM-4_DB_REQ_FAIL messages are logged at severity 4 in the event log. The log entries will look similar to the following: 08-00323 05/15/2001-00:51:31 SHM_-4-DB_REQ_FAIL shmDiskHdl 0x803276b4 SHM ERR: Database request on slot 8 failed, db = rslot.

Conditions: Consecutive resetcd were executed on the PXMs in this node. This log can be seen under 2 conditions: 1. Under the normal operation of the PXM if this is logged, it is a problem with the communication between 2 tasks that needs to be investigated. 2. During any form of shelf reset like resetsys, abortrev, setrev etc. If this log is seen at around the time a shelf reset is happening, it is not a problem if this log is seen. This will not have any impact at all on the state of the shelf or the state of the configuration on the shelf.

Workaround: None.

Hardware: PXM45

CSCdu27030

Symptom: OAM CC Activation Cell correlation tag is incorrectly modified.

Conditions: User notes that an F4-Seg Active-CC OAM cell with a correlation tag of 0x6A is returned to the sending device with a correlation tag of 0x00.

Workaround: None.

Hardware: AXSM1

CSCdu29780

Symptom: The line admin state is down because either there is NO DISK RECORD on the line, the line is defaulted to admin state down, or the disk record is there but it shows admin state down.

Condition: Upgrading from older version to newer version and doing setrev's on multiple cards at the same time.

Workaround: Do setrev on each card and wait until that is complete before doing the next card.

Hardware: PXM45

CSCdv50574

Symptom: Incorrect usage statement generated.

Condition: When the delapsln cli command is executed.

Workaround: None.

Hardware: AXSM1

CSCdv69400

Symptom: addchanloop on AXSME doesn't have option 2. Local loop in loopback.

Condition: When addchanloop on AXSME.

Workaround: Not known.

Hardware: AXSME

CSCdx62800

Symptoms: MGX45 CLI Reference Manual needs updated.

Conditions: 4 new commands missing out of the manual.

Workaround: None.

Hardware: PXM45/B

CSCdx82847

Symptom: Line status LED's on standby PXM1E always show green.

Conditions: The line status LED on standby PXM1E are always show green even if the line is in LOS. This is inconsistent with other LEDs on the PXM1E. e.g., the ALARMs LEDs on the standby PXM1E remain OFF. We think that the line status LED should either reflect same as the active PXM1E or they remain OFF as of alarm LED.

Workaround: None.

Hardware: PXM1E

CSCdy09657

Symptom: dspdiagstatus does not display the state and role of SM's; It displays the info

only for the PXM1E and SRM cards.

Conditions: The PXM1E dspdiagstatus command does not display the state and role of SM's whereas the same command displays the state and role of the SM's in nodes with

the PXM45. In case of a PXM1E node, the role and state info for SMs should say N.A (or something similar to indicate that NBSMs status is not displayed by this command).

Workaround: None yet. Currently, "Idle/Unknown" is the role/state combination that is used to indicate that diags status does not apply to SM's.

Hardware: PXM1E

CSCdy10480

Symptom: Default 0 SCT is not shown for FRSM12

Condition: Execute dspscts

Workaround: The system will allow the user to configure port and card level SCTs even though the display does not show it.

Hardware: PXM45

CSCdy16930

Symptom: addpart command is inconsistent when entering parameters.

Condition: addparts commands takes hex values for some fields, for example if a value 3a is given for the field minVCI it would take that value and show as 58 which is decimal for 3a. Customer expects that a error message would pop up.

Workaround: Unknown.

Hardware: PXM1E

CSCdy23797

Symptom: pntrace commands not completely documented

Condition: MGX CLI Manual vs the troubleshooting guide.

Workaround: None. Trace commands beginning with pn will not be documented, because they are not customer commands. Thirteen new trace command are documented in the MGX PXM Command Reference, currently located at http://lbj.cisco.com/push_targets1/ucdit/cc/td/doc/product/wanbu/8850px45/release3/cmdref/index.htm"

Hardware: PXM45/B

CSCdy36692

Symptom: Need warning messages for cnfport

Conditions: Warning messages are needed to inform the user that cnfport is going to be changed.

Workaround: None.

Hardware: PXM1E

CSCdy37182

Symptom: dspcd shows lower back card empty for a full height back card.

Conditions: None.

Workaround: None. Not service impacting, only a display issue.

Hardware: all

CSCdy41895

Symptoms: 'dspportsct vcThr' should match with the one shows on 'dspportsct qeVcThr' But the VSI_Signal values shown from SCT does not match to the actual HW value.

Conditions: dspportsct vcThr & dspportsct qeVcThr

Workaround: This is a display problem. The VSI_Signal VC Threshold values being display from the dspportsct or dspcdsct command is incorrect. Basically the AXSME software ignores the VC Threshold values being specified in SCT. Instead, the AXSME software would program a lower pre-defined threshold values for the VSI Signal channels. So the values in the HW are correct. Please ignore the VSI_signal values from the SCT. The lower pre-defined is needed because we want to limit our traffic flow on the VSI signaling channels prevent flooding the PXM45. If the PXM45 is flooded, then there will be some unpredictable and unreliable behaviors on PXM45. We are going to fix the display problem.

Hardware: AXSME

CSCdy42620

Symptom: Danglers remain after using the CLI command delcons. This is the caveat with these commands. While provisioning connections in bulk (copycons/delcons), if the PNNI layer get busy due to re-route/de-route activity, then it will reject the deletion.

Conditions: The command delcons was developed for Dev-test usage only. This command is not recommended to be used on a production node due to resource problems generated by the flood of traps on each con deletion.

Workaround: Use delcon for each individual PVC until a better method is developed see PXM release notes for description of cli commands delcon and delcons usage.

Hardware: frsm12

CSCdy46972

Symptom: Adding APS lines on the down lines does not show the correct error message.

Conditions: Adding APS lines on the down lines does not show the correct error message. It shows as ERR:APS not allowed:wrong card type. On the PXM-45 it shows the correct error as ERR: working line must be up.

Workaround: Unknown.

Hardware: PXM1E

CSCdy46993

Symptom: APS command "clradjlnalmcnt" does not show the command option clearly

Condition: emeanw36.8.PXM.a > clradjlnalmcnt 2.9 clradjlnalmcnt "<X.line>". It is not successful in the above format. But it also has another option as given below and it is successfully taking the command in that option. PXM.a > clradjlnalmcnt clradjlnalmcnt -<lineType> "<slot.line>" PXM.a > clradjlnalmcnt -sonet 2.9 Note: In MGX-45, it has only one option and it is successful. AXSM.a > clradjlnalmcnt clradjlnalmcnt "<bay.line>" AXSM.a > clradjlnalmcnt 1.3 AXSM.a > clradjlnalmcnt 1 clradjlnalmcnt "<bay.line>" AXSM.a >

Workaround: Unknown.

Hardware: PXM1E

CSCdy49757

Symptom: AUSM channel, port and SAR counters do not correctly count RM cells received from CPE

Condition: The AUSM channel, port and SAR counters do not correctly handle RM cells when they are generated by the CPE (test-set). When RM cells are received by the AUSM card the baseline behavior is that they should be discarded by the UNI port. Indeed that is what is noted to happen for AUSM on PXM1E. The command dspconload" shows that no traffic is received from the AUSM when a stream of RM cells at 480 cps is generated by the test-set:

Workaround: Unknown.

Hardware: AUSM-8T1E1

CSCdy54607

Symptom: PXM command line interface paused indefinitely and would no longer accept commands.

Conditions: Occurred after executing the memshow<noCmdBold) command from the command line interface.

Workaround: None.

Hardware: PXM45

CSCdy59294

Symptom: AUSM/PXM1E transmits invalid PTI=7 cells into network but cannot pass traffic out of far-end AUSM port.

Condition: An abr1 PVC was provisioned between two AUSM-IMA ports: [Test Set A] <---> node1 to node2 <---> [Test Set B] Test set A generated 480 CPS of ATM cells with the PTI field set to 7 (invalid). The payload consisted of 48 byte 6A pattern. The channel, port and SAR counters on node1 indicate that traffic is being sent into the network. On the PXM1E card on node1 the "dspconload" command indicates that all the PTI=7 traffic is sent out the trunk interface. In fact there seems to be RM cell overhead in both directions. The "dspconload" command on node1 indicates that all PTI=7 traffic is being received on the trunk interface. However on the AUSM port on node2 the chan, port and SAR counters all remain at zero. It is very strange that the AUSM card handles PTI=7 cells differently on the Ingress and Egress directions. At one time the PVC was able to transmit PTI=7 cells end to end but it has only been observed to happen once.

Workaround: Unknown.

Hardware: AUSM-8T1E1

CSCdy59923

Symptom: Mounting nfs is not necessary, takes time and resources and can cause conflicts when nfs host is the same as another device.

Conditions: Nfs host is mounted when coming up.

Workaround: None.

Hardware: PXM45/B

CSCdy59933

Symptom: Attempt to low level format with diskFormat and ataFormat fails on PXM-HD with the following error. pxm45bkup>diskFormat "C:" IDE: format in progress. This takes a while ........ .Device abort error .... status is 51 error is 10 Couldn't format "C:". value = -1 = 0xffffffff pxm45bkup>.

Conditions: This condition is observed in 2.1 Release when the PXM-HD model is IC25N020ATCS04-0 or IBM-DJSA-205. The HDD model name can be viewed with the command ataShow. cmdBold>More Information: A low level format is not required in the field as these drives come preformatted from manufacturing. Using sysClrallcnf and recreating the file system with sysDiskCfgCreate will help to reinitialise a PXM-HD in the field.

Workaround: None.

Hardware: PXM45

CSCdy62765

Symptom: Standby PXM reset. The dsplog will look similar to the following example (slot 8 is active, 7 is standby in this example): 08A98502 09/05/2002-16:48:56 SHMA-7-FATAL_ERR_RPT E:00317 pnRedman shmRamSyncFatalErrRepor shmRamSyncFatalErrReport: AppId 0x1000c, tId 0x10054, tName pnRedman , Ref. pslot 7, callerPc 0x807c68e8, evtNum 0x1000 08A98509 09/05/2002-16:48:56 REDM-6-RmRamDbReset pnRedman checkSyncRamResetState Redman receive reset from RAMDB.

Description

CSCdt54958

Symptom: OC12 p-p jitter amplitude exceeded the 0.10 UI pp.

Conditions: Unknown.

Workaround: None.

Hardware: AXSM1

CSCdw27075

Symptom: Unable to switchcc to a AXSM card in Y-redundancy configuration. The reason for that is that QE VI threshold has been exceeded and QE is discarding the incoming AAL5 frames. This situation may be met in PXM45A, where SAR overflow may occur (very rare). Note: customer should not let QE SAR overflow occur in PXM45A

Conditions: After a switchredcd on an AXSM card pair in redundant mode.

Workaround: None.

Hardware: PXM45

CSCdx33812

Symptom: Xbar planes being shut done on the PXM45B.

Conditions: Xbar errors being reported between slots 3, 7, and 8.

Workaround: None.

Symptom: All external xtags are down. Attempts to switchcc to slot 5 (containing xtag interfaces) failed.

Conditions: Standby PXM in slot 8 in empty reserve state. There are some P1SarErrors reported to the active PXM log.

Workaround: None.

Hardware: axsm1b_oc12

CSCdy11654

Symptom: User can neither "cc" nor "ccc" (high primary) to any slot with an RPM seated in it. "cc" to any other slot containing any other card type succeeds.

Condition: IOS IPC memory buffer leaked for 21 days, zero resource were available for IPC, when this situation occurred. The MGX shelf is operating in simplex mode.

Workaround: "switchcc" with duplex shelf "resetcd" with simplex shelf.

Hardware:PXM45B

CSCdy37036

Symptom: AXSM-E card was failed after upgrading and on line diag cycle.

Conditions: Card was upgraded.

Workaround: Use the default SCT files provided for CARD SCT (AXSME_SCT.CARD.5) or change the CosB Max thresholds of all CosBs to be less than 300,000 in the SCT file.

Hardware: frsm12

CSCdy61482

Symptom: SRM cards come up in failed state as seen with dspcd or dspcds

Conditions: Node is coming up following a power failure or resetsys and the SRM(s) are removed and re-inserted while the PXM is in the active state

Workaround: None

Hardware: PXM1E

CSCdy65077

Symptom: Standby AXSM hung for approximately one minute - caused data loss.

Conditions: Upon the execution of the switchredcd on slot #11 to #12.

Workaround: None.

Hardware: AXSMB-OC3

CSCdy66033

Symptom: Connections fails and doesn't route

Conditions: MGX 8830, MGX 8850

Workaround: Under investigation

Hardware: PXM1E

CSCdy75309

Symptom: After the node was powered down, connections were still in OK state.

Conditions: Connections existed between two PXM1E nodes. When one node was downed, the connections on the other end went into the failed state. However, some connections (about 50 out of 2500) were still shown as OK on the switch.

Workaround: Unknown.

Hardware:PXM1E

CSCdy81906

Symptom: Slots 1 and 2 rebooted and failed.

Condition: After a burnboot slot #8 and switchcc was executed on the shelf.

Workaround: None.

Hardware:PXM45B

CSCdy81930

Symptom: Port failed for over 9 minutes.

Condition: Unknown.

Workaround: None.

Hardware:axsm1b_oc12

CSCdy82098

Symptom: Node failed to establish connections, and ports go to building state etc.

Conditions: Heavily populated node with PXM45A cards.

Workaround: Do resetsys.

Hardware:PXM45

CSCdy82600

Symptom: Inconsistent redundancy on CESM cards on MGX 8850 with PXM1E.

Conditions: Ungraceful upgrade was in progress for three cards in this slot. After the upgrade, 1:n redundancy was configured (slots 25 & 26 as active, slot27 as standby). Resetcd on slot 25 changed this state to standby and slot 27 to active for "dspcds". However, after "cc" from pxm slot 25 is active and 27 standby.

Workaround: Unknown.

Hardware:PXM1E

Symptom: Core dump occurred for standby AXSME OC3 card though no activities.

Conditions: AXSMEOC3 with standby card.

Workaround: Unknown.

Hardware: AXSME

CSCdw91580

Symptom: SRME APS switchover time > 250ms when either SRME front card or back card is removed.

Conditions: When SRME is engaged in APS and either SRME front card or back card is removed.

Workaround: Perform APS switching out from back card that need to be removed. It means that before removing the SRME card, insure that the SRME card is in standby state instead of active.

Hardware: PXM1E

CSCdx17118

Symptom: Slower and partial reroutes for connections routed over trunks with errors or delay.

Conditions: Introducing delay and bit errors on trunks between peer groups causes connection reroute delays.

Workaround: Unknown.

Hardware: PXM45

CSCdx45116

Symptom: Some of the connections are in alarm after stopbert testing

Conditions: cnfbert, startbert then stopbert

Workaround: dncon/upcon or dnport/upport can recover the connection from the alarm status.

Hardware: AXSME-IMA

CSCdx57346

Symptom: Intercard communication is lost between PXM and AXSM cards.

Conditions: User cannot access (CC) other cards in MGX2 chassis. Redundant PXM remains in init state.

Workaround: None.

Hardware: PXM45B

CSCdx59814

Symptom: Routed conns remain ok (no AIS) on line or card failure.

Conditions: Two nodes with PXM1E-IMA cards and an frsm card each. Add one frsm port on the frsm card on each node. Add 1000 master end points terminating on frsm on Node1 and 1000 slaves end points terminating on frsm on Node2. Execute the test case FAIL_RECOVER_2 and FAIL_RECOVER_3. Some of the connections on the remote end still remain OK when they supposed to be in fail state.

Workaround: None

Hardware: FRSM-8T1E1

CSCdx62011

Symptom: Add imagrp to the node cause card to be in critical alarm, and when the other end imagrp is added, the active PXM1E on both nodes show card in critical alarm. Deleting all imagrp on both node, still show that the active PXM1E on both node in critical card alarm.

Conditions: Active PXM1E show critical card alarms

Workaround: Cause the active PXM1E to be reset (switchcc or resetcd)

Hardware: PXM1E-IMA

CSCdx86863

Symptom: Low throughput for small frame size for the FRSM8T1- FRSM8T1-C ABRSTD-NIWPVC

Conditions: The ABR Standard NIW PVC is configured from FRSM8T1--C on the cokemt36 to FRSM8T1-C on the emeagr36. The PVC values are CIR=1536 Kbps PIR=1536 Kbps IBS=2000 BC=65535, BE=65535. All other values are as per engineering and given below for your reference. The data-generator is connected to one of the FRSM port and other side of the FRSM port is looped. Data throughput decreases when the frame size decreases. The throughput values with different frame size is given below. FRAME SIZE THROUGHPUT 4510 Bytes 98% PIR 2000 BYTES 98% PIR 1500 BYTES 98% PIR 1000 BYTES 98% PIR 512 BYTES 97% PIR 256 BYTES 89%PIR 128 BYTES 89%PIR 64 BYTES 68%PIR

Workaround: Unknown.

Hardware: FRSM-8T1E1

CSCdx89271

Symptom: The RPM in slot 13 failed to load the primary config file. The RPM recovered in a standby state, with the default config as the running config.

Conditions: The RPM at slot 13 has a 1.3 MB config file. The RPM are configured for 1:n redundancy, with slot 4 covering each slot. The redundant slot (4) did not have a card inserted during the node recovery from the rebuild caused by dip in voltage from the power source.

Workaround: Unknown.

Hardware: PXM45B

CSCdy07641

Symptom: dspcdalms and dspcdstatus 13 both shows wrong info for slot 13.

Conditions: dspcdalms shows that slot 13 has -30 minor alarms and the command dspcdalms 13 specifies that it has -30 channel alarms. but slot 13 has a total of 10 channels on it which are in ok state. showed by dspcons.

Workaround: Unknown.

Hardware: FRSM-8T1E1

CSCdy09052

Symptom: dsphotstandby runs into infinity loop.

Conditions: Do PXM switchover while dsphotstandby is in progress.

Workaround: None.

Hardware: PXM45

CSCdy22021

Symptom: tOam task was leaking memory in IPC buffer ids 0x10002 and 0x10003.

Conditions: Unknown.

Workaround: Unknown.

Hardware: PXM1E

CSCdy22633

Symptom: Only on a specific node, and only on a specific slot pair, does the dspcons and dspcons -filt 4 command give syntax error usage information even though the command was correctly entered. Commands provide expected output on other slots in the node, and in the same slots in different nodes, the problem is not seen. Also there is also an error message logged for slot 11 every time the command "dspcons -filt 4" is issued, "cliCallXfunc: xFunc() Parameter validation failed non MIB-based command:".

Conditions: The dspcons command with the filter option had failed due to the presence of connections on a port that did not exist. This could have been caused by two possible scenario: a) the port had disappeared off the port database, b) the connections were "dangling" connections that did not get cleaned up as part of a delete operation. Most of the clues found in the logs point to the latter.

Workaround: The problem is not malignant and does not impact the normal functioning of the switch, a) It does not impact traffic, b) provisioning operation on the node should be possible, c) the port can be re-added if necessary and connections can be provisioned on the port. The only connections that cannot be re-added are those which are dangling in the database. d) The only impact of the dangling connections is that it reduces the number of connections that can be provisioned in the card. The problem can be rectified by deleting the dangling connections on the card.

CSCdy63336

Symptom: pnRedMan task is leaking memory in IPC pool 0x10002 and 0x10006 in a PXM1E.

Conditions: One possible way to cause this IPC leak is that there are some plug-and-play ports on a given slot A (i.e., the port shows up on controller when slot A is active, but disappears when the slot is reset or pulled out), and the slot A is reset/pulled out for a short time.

Workaround: To avoid above condition, make those ports persistent, by dnpnort/cnfpnportsig, etc.

CSCdy70426

Symptom: 1. The bypasses are not ordered by AvCR. This means that bypasses with smaller bandwidth can be advertised ahead of ones with more bandwidth. However in most cases, the bypasses are advertised as full-meshed instead of spanning tree, so that the ordering of bypasses wouldn't matter, since all the bypasses are advertised. 2. The routing cost is not calculated correctly for via peer groups that are configured as complex nodes. This could affect finding an optimized route in MPG network.

Conditions: The complex node that is turned on a node with a lot of bypasses

Workaround: None.

CSCdy70541

Symptom: Primary clock status is lockable but still the active clock is internal clock...

Conditions: The primary clock was configured from trunk 7:2.2:22 and it was active. The secondary clock was configured from trunk 7:2.11:11 and was in bad state because of no clock signal. To clear this problem from secondary clock the "cnfclksrc secondary 7:2.9:29" command was executed. The trunk 7:2.9:29 was an active trunk with PNNI-link established both ways. After executing this command the active clock status became from "internal clock" even though the primary clock is still in locked state. Also, the secondary clock is still shown as 7:2.11:11 instead of 7:2.9:29. Moreover, the status of secondary clock has became "UNKNOWN"

Workaround: Port 2.11:11 is oper down. Bring it up active (either by loopback or physical cable) delclksrc secondary configure new clock source.

CSCdx82847

Symptom: line status LED's on standby PXM1E always show green

Conditions: The line status LED on standby PXM-1E always show green even if the line is in LOS. This is inconsistence with other LEDs on PXM-1E. e.g. the ALARMs LEDs on the standby PXM remain OFF. We think that the line status LED either reflect same as of active PXM or they remained OFF as of alarm LED. (On PXM-1 they remain OFF on standby PXM)

Workaround: None.

Hardware: PXM1E

CSCdy09657

Symptom: dspdiagstatus does not display the state and role of SM's; It displays the info only for the PXM1E and SRM cards.

Conditions: PXM1E dspdiagstatus command does not display the state and role of SM's where as same command displays the state and role in MGX-45. In case of a PXM1E node, the role and state info for SMs should say N.A (or something similar to indicate that NBSMs status is not displayed by this command)

Workaround: None yet. Currently, "Idle/Unknown" is the role/state combination that is used to indicate that diags status does not apply to SMs. This will be changed soon.

CSCdy41895

Symptom: 'dspportsct vcThr' should match with the one shows on 'dspportsct qeVcThr' But the VSI_Signal values shown from SCT does not match to the actual hardware value.

Conditions: dspportsct vcThr & dspportsct qeVcThr

Workaround: This is a display problem. The VSI_Signal VC Threshold values being display from the dspportsct or dspcdsct command is incorrect. Basically the AXSME software ignores the VC Threshold values being specified in SCT. Instead, the AXSME software would program a lower pre-defined threshold values for the VSI signal channels. So the values in the hardware are correct. Please ignore the VSI_signal values from the SCT. The lower pre-defined is needed because we want to limit our traffic flow on the VSI signaling channels prevent flooding the PXM45. If the PXM45 is flooded, then there will be some unpredictable and unreliable behaviors on PXM45. We are going to fix the display problem.

Hardware: AXSME

CSCdy42250

Symptom: A difference exits between the checksum on the switch software distributed AXSME_SCT.PORT.53.V1 and the same AXSME_SCT.PORT.53.V1 after it has been uploaded and re-downloaded to the same switch using the SCT download.

Conditions: SCT file has been upload and re-downloaded to the same switch using the SCT download from CWM.

Workaround: First load the distributed SCT on the switch with addsct command. Once CWM and the SCT manager has detected the SCT. Remove the distributed SCT from the switch using the delsct command. Now the SCT can be load to all nodes requiring this SCT with the SCT download via from CWM. Most importantly there is nothing different between the two SCT files with respect to card parameter. The difference with the SCT files is in the SCT IDs in this case the 53 number. In the SCT manager it is recorded as 53 on the distribution SCT file it's recorded internally as 1. The CWM SCT is correct. Both will work.

Hardware: frsm12

CSCdy42620

Symptom: Danglers remain after using the CLI command delcons. This is the caveat with these commands. While provisioning connections in bulk (copycons/delcons), if the PNNI layer get busy due to re-route/de-route activity, then it will reject the deletion.

Conditions: The command delcons was developed for Dev-test usage only. This command is not recommended to be used on a production node due to resource problems generated by the flood of traps on each con deletion.

Workaround: Use delcon for each individual PVC until a better method is developed see PXM release notes for description of CLI commands delcon and delcons usage.

Hardware: frsm12

CSCdy43404

Symptom: Card alarm is not properly counted when using dspcdalms

CSCdy49757

Symptom: AUSM channel, port and SAR counters do not correctly count RM cells received from CPE

Conditions: The AUSM channel, port and SAR counters do not correctly handle RM cells when they are generated by the CPE (test-set). When RM cells are received by the AUSM card the baseline behavior is that they should be discarded by the UNI port. Indeed that is what is noted to happen for AUSM on PXM1E. The command dspconload shows that no traffic is received from the AUSM when a stream of RM cells at 480 cps is generated by the test-set:

Workaround: Unknown.

Hardware: AUSM-8T1E1

CSCdy53146

Symptom: S1 byte for Synchronization Status Messaging not implemented properly.

Conditions: On the AXSMB/OC12, and the AXSMB/STM1

Symptom: No consistency in the warning message for invalid login attempts.

Conditions: When attempting to login to the shelf with incorrect User ID and password.

Workaround: None.

Hardware: PXM45B

CSCdy59294

Symptom: AUSM/PXM1e transmits invalid PTI=7 cells into network but cannot pass traffic out of far-end AUSM port.

Conditions: An abr1 PVC was provisioned between two AUSM-IMA ports: [Test Set A] <---> emeagr36.1.1.300 to emeanw36.27.1.1.300 <---> [Test Set B]. Test set A generated 480 CPS of ATM cells with the PTI field set to 7 (invalid). The payload consisted of 48 byte 6A pattern. The channel, port and SAR counters on gr36 indicate that traffic is being sent into the network. On the PXM1e card on gr36 the "dspconload" command indicates that all the PTI=7 traffic is sent out the trunk interface. In fact there seems to be RM cell overhead in both directions. The "dspconload" command on emeanw36 indicates that all PTI=7 traffic is being received on the trunk interface. However on the AUSM port on NW36 the channel, port and SAR counters all remain at zero. It is very strange that the AUSM card handles PTI=7 cells differently on the Ingress and Egress directions. At one time the PVC was able to transmit PTI=7 cells end to end but it has only been observed to happen once.

Workaround: Unknown.

Hardware: AUSM-8T1E1

CSCdy59858

Symptom: Using inband management, not able to ping pxm1 feeders atm0 address when the PXM45's lnPci0 and atm0 subnet masks are different. The trigger is the deletion of the internal SVC between the AXSM and the PXM. Can be reproduced by doing a dnport/upport on the AXSM port which connects to the management router in the setup shown below: CWM station---ethernet---Router with ATM oc3 interface-----AXSM------PXM45-----AXSM-----PXM1

Conditions: Observed on MGX 8850 PXM45 running 2.1.75

Workaround: The problem is in the VxWorks routing table on the PXM45. The IP data to pxm1 first has to traverse PXM45 where it is switched to the AXSM connecting to the pxm1. 1. Switchcc on the PXM45 clears this condition. 2. Making PXM45 re-learn the route to pxm1 clears this issue. This can be done by initiating a telnet from PXM45 CLI to pxm1.

Hardware: PXM45B

CSCdy59923

Symptom: Mounting nfs is not necessary, takes time and resources and can cause conflicts when nfs host is the same as another device.

Conditions: This condition is observed in 2.1 Release when the PXM-HD model is IC25N020ATCS04-0 or IBM-DJSA-205. The HDD model name can be viewed with the command ataShow. cmdBold>More Information: A low level format is not required in the field as these drives come preformatted from manufacturing. Using sysClrallcnf and recreating the file system with sysDiskCfgCreate will help to reinitialize a PXM-HD in the field.

Workaround: None.

Hardware: PXM45

Bug ID
Description
S1Bugs

CSCdt54958

Symptom: OC12 p-p jitter amplitude exceeded the 0.10 UI pp.

Conditions: Unknown

Workaround: None.

Hardware: AXSM OC-12 cards

CSCdu86213

Symptom: Cannot get large files from a switch using FTP. Data Connection Error is reported.

Conditions: When a large file is uploaded from a shelf to a workstation, the Ethernet chip hangs and a data connection error is reported by the FTP client on the workstation.

Workaround: Do not FTP files from on a workstation which is on the same subnet as the shelf.

Hardware: PXM45

CSCdw27075

Symptom: Unable to CC to a AXSM card in Y-redundancy configuration. The reason for that is that QE VI threshold has been exceeded and QE is discarding the incoming AAL5 frames. This situation may be met in PXM45A, where SAR overflow may occur (very rare). Note: customer should not let QE SAR overflow occur in PXM45A.

Conditions: After a switchredcd on an AXSM card pair in redundant mode.

Workaround: None.

Hardware: PXM45

CSCdx33812

Symptom: Xbar planes being shut done on the PXM45B.

Conditions: Xbar errors being reported between slots 3, 7, and 8.

Workaround: None.

Hardware: PXM45B

CSCdx48370

Symptom: CBM1 throughput is 42% of OC-3 LR as opposed to 100% OC-3 LR.

Conditions: Inject OC-3 LR traffic

Workaround: None.

Hardware: PXM1E

CSCdx53377

Symptom: SPVC fails after it was created

Condition: SPVC failed because the service module was in an unreserved state.

Workaround: 1) Call an api from the shell to re-reserve the slot

sh>shmRemoteFrontCardReservedReport (logical_slot #).

2) Delete the ports, parts, connections on slots and readd them.

Hardware: PXM1E

CSCdx54945

Symptom: All external xtags are down. Attempts to cc to slot 5 (containing xtag interfaces) failed.

Conditions: Standby PXM in slot 8 in empty reserve state. There are some P1SarErrors reported to the active PXM log.

Workaround: None.

Hardware: PXM45

CSCdx57063

Symptom: Resource (lcn, vpi/vci) leak on NNI trunks.

Conditions: Resetcd on service modules (where SPVC are terminated) and then deroute connections by using one of the following methods:

a. reset via/remode node

b. bring down NNI trunks

c. rrtcon/dncon

Workaround: None.

Hardware: PXM1E

CSCdx61357

Symptom: MGX-RPM-XF-512 card froze and no crashinfo was logged.

Conditions: Traffic was being pumped (182Mb/s) into 1 LVC.

Workaround: None.

Hardware: MGX-RPM-XF-512

CSCdx65568

Symptom: When active PXM1E trunk backcard is removed, switchover traffic outage is sometimes 1.5 sec or more.

Conditions: None in particular.

Workaround: None.

Hardware: PXM1E

CSCdx69070

Symptom: Several possible symptoms including:

- Inability or sporadic ability, to connect via telnet

-"gray-out" of the node on the CWM topology map

- no output from or receipt of an error message from 'dsplog' command or file system listing command 'ls' or other commands

- standby PXM45 or AXSM service modules which remain in the "Boot" and/or "Init" or alternate between the two after a reload

- inconsistent connection alarms on slave and master. (one side reporting alarm, the suspect side not)

Conditions: System memory and/or file handle allocation may get into a marginal or maxed out state due to "ungraceful" exit from the 'dsplog' command multiple times. This includes exiting display of the command with any other method other than using the 'Q' option to quit or going to the end of the output.

Workaround: On redundant systems with healthy standby PXM45 present, switchcc. On non-redundant systems: reset the single PXM45.

Hardware: PXM45

CSCdx77614

Symptom: Multiple nodes with failed PXM45Bs (standby) and active-f (active).

Conditions: When simulator nodes are sending addresses of length zero.

Workaround: resetsys, or switchcc as long as the simulator is off.

Hardware: PXM45B

S2 Bugs

CSCdt53631

Symptom: LOF criteria is not met per R5-225, for AXSM OC12 interface.

Condition: OOF condition is cleared at the presence of three consecutive error free patterns rather than two.

Workaround: Unknown.

Hardware: AXSM OC-12 cards

CSCdu26365

Symptom: Card resets with device driver error or watchdog timeout.

Conditions: Unknown.

Workaround: None.

Hardware: PXM45

CSCdu86213

Symptom: Cannot get large files from a switch using ftp. Data Connection Error is reported.

Conditions: When a large file is uploaded from a shelf to a workstation, the ethernet chip hangs and a data connection error is reported by the ftp client on the workstation.

Workaround: Do not ftp on a workstation which is on the same subnet as the shelf.

Hardware: PXM45

CSCdv53825

Symptom: sframetick lock config is lost.

Condition: When a switchcc is executed on the shelf.

Workaround: None.

Hardware: PXM45

CSCdv73419

Symptoms: Traffic loss on multi cast root connections with no indications of cell loss in any discard counters.

Conditions: During ingress multi cast or slot multi cast, the switch may issue a grant for a root cell when it can not deliver to all requested slot destinations. This will only occur if there is a switch port alarm on a service module that is the target of a multi cast root cell.

Workaround: There is no workaround. You can take action to remove the switch port alarm. If there are no switch port alarms then the problem will not occur.

Hardware: AXSM

CSCdv85607

Symptom: Core dump occurred for standby AXSME OC3 card though no activities.

Conditions: AXSME OC3 with standby card.

Workaround: Unknown.

Hardware: AXSME OC-3 cards

CSCdw64682

Symptom: AXSM core dumped.

Conditions: On-line diag error (Xbar burst) was reported at the time.

Workaround: None.

Hardware: AXSM OC-12 cards

CSCdw68448

Symptom: The low accuracy of AXSM's MBS policing function for Rel.2.0 and 2.1.

Condition: None.

Workaround: None.

Hardware: AXSM

CSCdw91580

Symptom: SRME APS switchover time > 250 ms when either SRME FC or BC is removed.

Conditions: When SRME is engaged in APS and either SRME FC or BC is removed.

Workaround: Perform APS switching out from back card that needs to be removed. It means that before removing the SRME card, check that the SRME card is in the standby state instead of the active state.

Hardware: PXM1E

CSCdw92648

Symptom: Connection's ingress Qbin number is not programmed correctly according the card's SCT file.

Condition: The card's SCT file is different from the port's SCT file.

Workaround: Use the same version of SCT files for both card and port.

Hardware: AXSME OC-12

CSCdw94593

Symptom: Cross commit failures between two shelves, and connection failures.

Conditions: May have been triggered by enni tuneup procedure, which included adding and deleting enni ports.

Workaround: None.

Hardware: AXSM

CSCdx07885

Symptom: The AXSM card went to fail state, when trying to invoke off line diag or coming out of off line diag. Card will remain and failed/empty state until manually addressed.

Conditions: The PXM trying to reset the AXSM card to start the offline diag or coming out of offline diag, the AXSM card is not getting reset and PXM declares it as in fail state.

Workaround: Resetcd manually.

Hardware: AXSMB OC-3

CSCdx08713

Symptom: display card alarms shows connections in Critical alarm. Traced them to chans on PXM1E but not shown anywhere else.

Condition: Not known how they got there. Unable to reproduce.

Workaround: None.

Workaround: None.

Hardware: AXSMB OC-3

CSCdx47744

Symptom: PXM cell bus can't handle more than 130 mbs per quadrant in any of the lower bay. PXM sends a corrupted cell (no end of frame) to the VISM and as a result VISM in slot 22 or 21 resets after all the buffers are filled out.

Condition: All 6 slots (slot 17 - 22) configured with G.711 , packet size = 10 ms and VAD off. 10 calls per sec per VISM.

Workaround: It should be ensured that the BW utilization does not exceed 130 mbs. G.711, 10 ms with VAD is not an ideal scenario. Customers using G.711 with VAD on or any of the compression codec should not have any problem.

Symptom: For downed connections, the "Operation status" field in "dspcon" command is displayed as "Failed" instead of "Down". The "Administration status" field shows the correct value "Down".

Conditions: When a Connection is brought down using "dncon" command, "dspcon" command shows the "Operational status" as "Failed".

Workaround: When the connection is down, in the output of "dspcon" command the "Operational status" field should be ignored and only the "Administration status" field should be considered.

Hardware: FRSM-12-T3E3

CSCdx53980

Symptom: SW cannot access any register and LCN Ram of QE (i.e. SW get the zero contents for all of QE registers). Data Path is still working. If it happens, then QE cannot be configured. So, addCon or delCon will fail and all of QE counts will become zero.

Conditions: After SW do a burst access to QE (3 QE write and 1 QE read) in resetQbin function.

Hardware: AXSM OC-48

CSCdx64484

Symptom: Traffic stopped after multiple "switchcc" were done on the PXM45. This is a hardware (Frame Relay FPGA IFE) bug found in the IFE Rev.55

Conditions: Ports 1 to 12 connected with a snaked connection. Tester pumped-in traffic into port 1, a VC connection is provisioned between port 1 and port 2, port 2 connected to port 3 with a cable, and so on. All the following ports connected like this. Port 12 looped-back the traffic with a cable connection. If the tester pumped-in T3 rate traffic, the whole FRSM12 card runs at 12 X T3 rate traffic. Now at the PXM45, do "switchcc". After multiple "switchcc" between slot 7 and 8, the traffic on FRSM12 may stop. How many times of "switchcc" will cause the traffic stop? It is random. In some chassis, 4 to 6 times. In most chassis, it takes 30 to 40 times switchcc to make this problem occur.

Workaround: To recover the FRSM12, reset the FRSM12.

Symptom: Lost primary and secondary clock after PXM switchover.

Conditions: Do PXM switchover by issuing switchcc.

Workaround: None.

Hardware: AXSME

CSCdx74626

Symptom: Discrepancy in connection status between FRSM12 CLI and CWM when Port alarm is cleared.

Conditions: When Port alarm occurs, all connections on the port go to Failed state in both Switch database and CWM (Cisco Wan Manager) database. Later, when the port alarm is cleared, all connections in Switch database go to Active state but the connections in CWM database stay in failed state.

When Port alarm occurs, the switch sends cwFrChanFailed(60618) for all connections on the port. But, when the Port alarm is cleared, the switch doesn't send cwFrChanActive(60617) trap.

Port alarm can occur when the line on which port is added goes to alarm state or when the LMI signalling fails.

Workaround: By initializing CWM Sync-up operation, the discrepancy in connection alarms can be removed. During Sync-up, CWM uploads Alarm file from the switch and updates alarm status of all connections. The Sync-up operation is periodic and happens once in 8 hours and the time is user configurable on CWM.

Hardware: FRSM-12-T3E3

Conditions: When configuring APS SFBER=10-3 only.

Workaround: None.

Hardware: PXM45B

CSCdx77485

Symptom: The PXM1E combo trunk back card has 12 lines. The top 8 lines are T3 or E3 and the bottom 4 lines are SONET lines. The 4 SONET lines have two LEDs per line. The top LED is meant to show the signal detect function. That is, if there is a signal on the incoming line, then this LED will glow a steady green. If there is no signal, this LED will blink green.

The LED on the bottom is meant to show the active/standby status of the line. In case of both Y-redundancy and APS configuration, the active line is steady green and standby is steady yellow.

Currently, the signal detect LED will be functioning correctly. But the status LEDs will be turned OFF always. It will not reflect the status of the line.

Conditions: Under all conditions, the status LEDs of the SONET lines on the combo back cards are OFF.

Workaround: In case of Y-Redundancy, the status of the lines can be found from the CLI command "dspcd". If the PXM1E front card is active, then all the lines are active. If the PXM1E front card is standby, then all the lines are standby.

In case of APS redundancy, the status of the lines can be found using the CLI command "dspapslns".

CSCdx7873

Symptom: Subagent did not registered with the master agent. SNMP requests to that card failed

Conditions: Switchcc, resetsys, or switchover and the SNMP subagent on the AXSM card failed to register with the SNMP master agent on the PXM.

Workaround: Need to manually register the SNMP subagent through shellconn.

1) Verify that the SNMP subagent is not registered for that slot:

a) nodeName.8.PXM.a > sh

b) Is this slot listed below?

pxm45>dispSubagents

dispSubagents

Subagent ID Shelf Number Slot Number

0 1 7

1 1 6

c) From above find the associated "Subagent ID" that corresponds to this slot. If it does not exist, then it is not registered with the SNMP master agent.

d) pxm45>dispSubagent 1

dispSubagent 1

Subagent ID = 1

Subagent Shelf = 1

Subagent Slot = 6

Subagent AgentID = smSubagent

Subagent State = 1 <===

Subagent RFD = 800112a

Subagent WFD = 60710d4

If the "Subagent State" is not 1, then the subagent is not registered with the SNMP master agent.

2) Manually register the subagent

a) cc to that slot

b) nodeName.<slot>.AXSM.a > sh

c) axsm1> SendWakeUpSsiMsg()

d) axsm1> ssiSemGive(SAGlobalLock)

e) repeat (1) to verify

Symptom: AXSME card is latched up when it receives high traffic of OAM loopback cells.

Condition: AXSME card can handle up to 10,000 OAM loopback cell per sec. If the user is sending OAM loopback cell at a higher cell rate, AXSME may be latched up and has unsuspected behaviour.

Workaround: If the user really want to pass OAM loopback at high cell rate, (s)he should enable the ingress channel loopback on the connection before (s)he starts to pump OAM loopback cell traffic. The command for enable the connection loopback is shown in the following. At CLI prompt: Enable connection loopback, addchanloop <ifNum> <vpi> <vci> <mode> Note: AXSME is supporting ingress channel loopback, so the valid parameter for mode is 1. Disable connection loopback, delchanloop <ifNum> <vpi> <vci>

Symptom: Danglers remain after using the CLI command delcons. This is the caveat with these commands. While provisioning connections in bulk (copycons/delcons), if the PNNI layer get busy due to re-route/de-route activity, then it will reject the deletion.

Condition: The command delcons was developed for Dev-test usage only. This command is not recommended to be used on a production node due to resource problems generated by the flood of traps on each con deletion.

Workaround: Use delcon for each individual PVC until a better method is developed see PXM release notes for description of cli commands delcon and delcons usage.

CSCdx43364

Symptom: The OID represents the interface name (ifName). The interface "sw1" is the main switch interface on the RPM. There can be only one main switch interface that can exist per RPM card and multiple sub-Interfaces. The switch subinterfaces (subinterfaces of the main switch interface) are represented by "sw1.x" on RPM. This snmp response is returned by the RPM. The ifTable does not display multiple instances for "sw1". The snmp query on ifName seems to always return "sw1" 5 times. This is not correct.

Condition: If we do snmpget on ifName, then it's possible to see multiple records for the same "Sw1" interface. To get the ifIndex for a particular interface, we can try to walk on ifDescr.

CSCdw66847

Symptom: Signalling thresholds on the cosb 16 not working in packet discard mode.

Conditions: If the signalling traffic is artificially pumped at a very high rate (ex: OC3/OC12) the qbin thresholds for cosb number 16 are discarding the cells indiscriminately.

Workaround: Change the signalling cosb number to 14 (it is available) in the card's SCT file.
