3.0.20 Software Release Notes for the Cisco SES PNNI Controller


Contents

This document contains the following sections:

About Release 3.0.20

These release notes describe the system requirements, new and changed procedures, upgrade procedures, and limitations that apply to Release 3.0.20 of the Service Expansion Shelf (SES) controller. These notes also contain Cisco support information. The 3.0.20 software release supports the Cisco WAN switching products: Cisco BPX 8600 series with SES controller.

SES PNNI and SVC Controller

Release 3.0.20 of the SES controller is compatible with the Cisco BPX 8600 series software Release 9.3.30 and with the later 9.3 Releases. The SES controller is connected to the Cisco BPX 8600 series switch via a BXM-155 (or T3/E3) port configured as a trunk. Redundant SES systems contain two controller cards which offer APS protection on the ports connecting to the BPX.

Feature Overview

The SES controller is a Virtual Switch Interface (VSI) controller which provides a Cisco BPX 8600 series wide-area switch the capability to create switched virtual circuits (SVCs) and soft permanent virtual circuits (SPVCs) using the User-to-Network Interface (UNI) and Private Network-to-Network Interface (PNNI) protocols. One SES controller is required for each Cisco BPX 8600 series node that will be originating, transporting, or terminating SVC/SPVC connections. The SES controller is offered in redundant or non-redundant configurations.

Detailed Feature Information

As networks grow in size, PNNI becomes a critical element in the ability to scale a network. PNNI provides a standard, interoperable, and scalable method to grow PVC (SPVC) networks to large sizes. In addition, applications such as voice, video, and LAN require WAN switches to provide dynamic connection capabilities in the form of SVCs. The SES controller provides the Cisco BPX 8600 series switch with a centralized controller for establishing SPVCs and SVCs in both the Cisco BPX 8600 series networks and in mixed vendor environments.

The Cisco BPX 8600 series switch in combination with the SES controller (Release 3.0.20) supports the following features:

Additional Deliverables

The SES controller MIB is being provided with the delivery of Release 3.0.20 of the SES controller software on CCO. The MIB is in standard ASN.1 format, and is included in the same directory where the SES controller software is located within CCO. The SNMP SES controller MIB file can be compiled with most standards-based MIB compilers.

Refer to the Cisco SES PNNI Controller Software Configuration Guide, Release 3, Appendix D, "SNMP Management Information Base," for a description of the MIBs supported by the SES controller.

New and Changed Information for Release 3.0.20

This section describes new and changed features in Release 3.0.20 of the SES controller.

SNTP

The SNTP feature enables BPX SES nodes with Time of Day (TOD) synchronization. This features allows BPX SES nodes to act as time of day (TOD) servers for the network. Accurate time of day service synchronized to Universal Time Coordinated (UTC). Through SNTP, the BPX SES node can 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. In a network of BPX SES and MGX switches, the TOD must be set on the BPX in order to be distributed consistently throughout the network.

Priority Routing of Connections

Use the priority routing feature to specify priority of connections, so that high priority connections will be established before low priority connections. During failures, high priority connections are released before low priority connections. High priority connections are rerouted and reestablished before low priority connections.

Preferred Routing of Connections

You can use the preferred routing feature to configure a connection's specific path through the network. Through this feature, a network operator bypasses automatic PNNI route selection. Connections are configured as either preferred routes or directed routes.

A preferred route follows the configured path if it is available. If the preferred route is not available, the connection reverts to a PNNI-selected route.

A directed route follows only the configured path. If the configured path is not available, the connection remains un-routed.

In this first implementation of Preferred routes, a set of preferred routes is configured and assigned reference numbers called "route sets." As connections are configured, they can be assigned to a particular route set. Each route set contains one preferred or directed route.

Preferred routes can be specified only across a single PNNI peer group. Preferred routes are interoperable with any standard PNNI implementation. You can control the selection of routes based on criteria other than those allowed in the route selection algorithms offered by PNNI.

Per Connection Based Utilization of SPVCs

The percentage utilization factor for SPVCs improves your control of network utilization for multiple tiers of service on networks supporting various trunk capacities. The percentage utilization factor is used for Connection Admission Control (CAC) for the connection. The actual bandwidth used for CAC is based on the following factors:

PCR/SCR configured for the connection

percentage utilization factor configured for the connection

percent utilization configured for interfaces in the selected path

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

Standards Based Path and Connection Trace

You can determine the path taken by a connection through the path and connection trace feature. The path trace feature collects information about the path of new connections in the process of being established. The connection trace feature is collects information on existing connections that have already been established. The path and connection trace feature conforms to the ATM Forum standard PNNI Addendum for Path and Connection Trace, Version 1.0 af-cs-0141.000. Path and connection trace is a standards based feature that enables SES interoperability with other vendor equipment.

Single-ended SPVC/SPVP Configuration

You can configure both the endpoints of the SPVCs at the master end of the connection. In previous releases, you could only configure double-ended SPVCs, which meant you had to configure both the master and slave ends of a connection. In Release 3.0.20, the slave end of the connection is activated when the connection is established by the master end. This feature enables improved interoperability with other vendor equipment and management stations.

100K Connections

Release 3.0.20 of the SES Controller allows 100 K connections. Since CWM can not support a large number of connections, the number of persistent SPVC connections is limited to 100 K.

SPVC and SVC real time statistics with MIB support

In addition to existing SPVC and SVC real time stats CLI dspconstats, the new dspchancnt command displays more per SPVC and SVC real time stats counters. The dspconstats command is a Release 3.0.20 feature, and is described in these release notes.

Table 5 describes the new counters dsplayed by the dspchancnt command contains the following:

Note The dspchancnt CLI is supported only on the BXM-E card. It is not supported on the legacy BXM card.



Note Both legacy BXM and BXM-E cards will continue supporting dspconstats CLI.


The CISCO-WAN-ATM-CONN-STAT-MIB file supports user access of real-time stats counters through the dspconstats and dspchancnt commands.

To display connection statistics for a port, enter the dspcconstats command as shown in the following

example:


SES-2.1.PXM.a > dspconstats <portid> <vpi> [<vci>]

Table 6 describes the dspconstats command parameters.

The SPVC connection statistics show the number of SPVC connections that are successfully routed, the number of connections that failed, and the number of crank backs initiated and received.

Upgrading the SES Node

Use the following procedure to upgrade an SES node:


Step 1 At the BPX node, upgrade the BXM firmware to MFR. For detailed information on BXM firmware upgrades, refer to the 9.3 Version Release Notes Cisco WAN Switching Software.

Step 2 At the BPX node, upgrade the BCC switch software to Release 9.3.35. For detailed information on BCC switch software upgrades, refer to the 9.3 Version Release Notes Cisco WAN Switching Software.

Step 3 Upgrade the SES controller to Release 3.0.20. The current boot image is pxm1_003.000.020.000_bt.fw. The current runtime software is pxm1_003.000.020.000_ses.fw.

The latest upgrade procedures are included in the sections that follow.

Step 4 If applicable, upgrade other feeders in your network to a newer release.


Upgrading to a New Software Release

This section contains installation and upgrade instructions. For complete details, refer to the Cisco SES PNNI Controller Software Configuration Guide, Release 3.0, part number 78-14258-01.


Note You can gracefully upgrade the SES controller software to Release 3.0.20 from Release 1.0.15, Release 1.0.16, Release 1.1.75, Release 3.0, and Release 3.0.10. If you are running a release prior to 1.0.15, you must upgrade to Release 1.0.15 before you can upgrade to Release 3.0.20.


When upgrading your node, upgrade the software in the following order:

1. PXM boot software

2. PXM runtime software

The following sections describe how to upgrade the PXM cards.

Special Installation and Upgrade Requirements

This section covers the procedures for upgrading the backup boot and runtime images for the following hardware:

Redundant controller card

Single controller card (the PXM)

Upgrading from SES Release 1.0.15, 1.0.16, 1.1.75, 3.0, or 3.0.10 to
Release 3.0.20

The procedures for upgrading the boot and runtime software are in the sections that follow.


Note Graceful upgrades to Release 3.0.20 are supported only from Release 1.0.15, Release 1.0.16, Release 1.1.75, Release 3.0, and Release 3.0.10. If you are running a release prior to 1.0.15, you must upgrade to Release 1.0.15 before you can upgrade to Release 3.0.20.


Upgrading the Backup Boot Image

This section provides instructions for upgrading the backup boot images from Release 1.0.15, Release 1.0.16, Release 1.1.75, Release 3.0, and Release 3.0.10 to Release 3.0.20. The boot upgrade can be graceful or non-graceful, depending on the type of card to be upgraded and the configuration of the node.

Upgrading the Backup Boot on Redundant Systems


Note Use the following procedure to upgrade the boot on both the active and the redundant controller cards. When performing upgrades on redundant cards, run this procedure on the standby card and not on the active card. This keeps the node in service during the upgrades. Before you upgrade the boot image, FTP the new backup boot firmware, pxm1_003.000.020.000_bt.fw, to the disk (should be the same as the PXM FW procedure.)


To upgrade the boot image on the active controller cards on redundant systems, follow these steps:


Step 1 Transfer the backup boot image to the card disk, as follows:

a. At the SES CLI, enter the dspipif command on the active controller card to find the node's IP address. The field internet address for lnPci 0 interface is the node IP address.

b. From the workstation containing the PXM backup boot image, enter ftp <Node IP address>.

c. Enter the username cisco.

d. Enter your password.


Note The default password is 1ciscoinc. If you have changed the default password to a new password, use your new password.


e. Enter the cd C:/FW command to get to the switch directory.

f. Enter the bin command (for a binary transfer).

g. Enter the put <PXM backup boot image name> command to transfer the backup boot and runtime files from the server to the switch directory C:/FW. See the following example:

put pxm1_003.000.020.000_bt.fw

Replace <PXM backup boot image name> with the boot image name. For Release 3.0.20 of the SES, the boot image name is pxm1_003.000.020.000_bt.fw.

h. Enter the bye command to end your session.

Step 2 At the SES controller CLI, enter the dspcds command to determine the standby card slot number.

Step 3 To verify that the boot IP for both the active and standby card is unique, enter the bootchange command.

Step 4 Press Enter until you see inet on ethernet (e). This is the boot IP address for the active PXM.

To change the boot IP address to make it unique, type a new address at the inet on ethernet (e) prompt.


Note Changing the boot IP address on the active PXM also changes it on the standby PXM.


Step 5 Enter the cc <slot number> command to change to the standby card.

ses1.1.PXM.a> cc 2

Replace <slot number> with the slot number of the card you want to work on.

Step 6 Type sh to go to the shellConn.

ses1.2.PXM.s> sh

Step 7 Enter the sysBackupBoot command.

PXM1> sysBackupBoot

Step 8 Press Return after you see the disk sync message to get back to active PXM.

Step 9 Exit or open a new telnet window. Telnet into the standby IP host inet address from Step 3.


Note An alternate way to get to the standby card is via the console port on the standby.


Step 10 Perform the following tasks to reset the card:

a. Verify that the card is at the pxm1bkup> prompt. If it is not, enter the sysBackupBoot shellConn command on the standby card.

b. Enter the sysPxmRemove command:

pxm1bkup>sysPxmRemove

After you enter the sysBackupBoot command, it takes about one minute for the active PXM to reset the card. If the active PXM resets the standby PXM, wait until it comes to the standby state (approximately four or five minutes), then telnet into the standby and repeat Step 5 and Step 6. After the sysPxmRemove command is entered, the active PXM can not reset the standby.

Step 11 Enter the cd "C:/FW" command from pxm1bkup> prompt to get the FW directory.

pxm1bkup> cd "C:/FW"

Step 12 Enter the ls command to verify that the boot firmware file is there.

pxm1bkup>ls

Step 13 Enter the sysFlashBootBurn <"boot firmware file name"> command to burn the image on the disk:

pxm1bkup>sysFlashBootBurn "3.0"

The system will ask if you want to proceed. Enter Y for Yes.

Step 14 When the pxm1bkup> prompt returns, enter the reboot command.

Flash Download completed...
value = 0 = 0x0
pxm1bkup> reboot

Step 15 Log in to the active PXM.

a. Enter the dspcds command to ensure the standby is in standby state.

b. Enter the dspcd <standby slot #> command to verify the firmware was loaded successfully.

Step 16 Load the backup boot onto the active PXM.

a. Enter the switchcc command to change cards.

ses1.1.PXM.a> switchcc 

b. Log in to the SES controller.

c. Perform Step 5 to Step 13 on the new standby PXM.


Upgrading the Backup Boot on Non-Redundant Systems

The upgrade of the boot on a non-redundant controller card is non-graceful. This means the traffic gets disrupted on the card during this operation. The upgrade can only take place when the card is in the BOOT stage. Because there is only one controller card, there will be a node outage as well.

For non-redundant systems, follow these steps to upgrade the backup boot:


Step 1 Transfer the backup boot image to the card disk using FTP as follows:

a. At the SES CLI, enter the dspipif command at the active controller card to find the Node's IP address. The field internet address for lnPci 0 interface is the node IP address.

b. From the workstation containing the PXM backup boot image, enter ftp <Node IP address>.

c. Enter the username cisco.

d. Enter your password.


Note The default password is 1ciscoinc. If you have changed the default password to a new password, use your new password.


e. Enter the cd C:/FW command to get to the switch directory.

f. Enter the bin command (for a binary transfer).

g. Enter the put <PXM backup boot image name> command to transfer the backup boot and runtime files from the server to the switch directory C:/FW. See the following example:

put 3.0

Replace <PXM backup boot image name> with the boot image name. For Release 3.0 of the SES, the boot image name is 3.0.

h. Enter the bye command to end your session.

Step 2 Log in to the SES.

Step 3 At the shell, enter the sysBackupBoot command to put the controller card into the PXM backup prompt stage.

pxm1>sysBackupBoot

The PXM card resets.

Step 4 Log in to the PXM.

Step 5 Enter the cd "C:/FW" command at the pxm1bkup> prompt to get the FW directory.

pxm1bkup>cd "C:/FW"

Step 6 Enter the ls command to verify the boot firmware file is there.

pxm1bkup>ls

Step 7 Enter the sysFlashBootBurn <"boot firmware file name"> command to burn the image on the disk.

pxm1bkup>sysFlashBootBurn"3.0"

The system will ask if you want to proceed. Enter Y for Yes.

Step 8 At the pxm1bkup> prompt, enter the reboot command.

pxm1bkup> reboot

The node resets.

Step 9 Log in to the node.

Step 10 Log in to active PXM.

Step 11 Enter the dspcd <active card> command to determine if the upgrade was successful.

ses1.1.PXM.a> dspcd 1


Upgrading the Cisco SES PNNI Runtime Image

This section provides instructions for upgrading the runtime images from Release 1.0.15, Release 1.0.16, Release 1.1.75, Release 3.0, and Release 3.0.10 to Release 3.0.20.

The upgrade of the runtime image on the redundant controller card is graceful. This means the traffic will not be disrupted. The new runtime image for 3.0.20 is pxm1_003.000.020.000_ses.fw.

Upgrading the Runtime Image on Redundant Systems

Follow these steps to upgrade the runtime image on redundant systems:


Step 1 Use FTP to transfer the runtime image to the card disk.

a. At the SES CLI, enter the dspipif command at the active controller card to find the node's IP address. The field internet address for lnPci 0 interface is the node IP address.

b. From the workstation containing the PXM backup boot image, enter ftp <Node IP address>.

c. Enter the username cisco.

d. Enter your password.


Note The default password is 1ciscoinc. If you have changed the default password to a new password, use your new password.


e. Enter the cd C:/FW command to get to the switch directory.

f. Enter the bin command (for a binary transfer).

g. Enter the put <runtime image name> command to transfer the runtime files from the server to the switch directory C:/FW. See the following example:

put pxm1_003.000.020.000_ses.fw

h. Enter the bye command to end your session.

Step 2 Enter the dspcds command to determine the standby slot.

Step 3 Enter the loadrev <standby slot> <image version> command to load the new version of runtime image on the controller card.

ses1.1.PXM.a>loadrev 2 3.0(20.0)

The standby card resets and comes up in the new revision.

Step 4 When the standby card is in the STANDBY state, enter the runrev <standby slot> <image version> command to run the new version of runtime image on the controller card.

ses1.1.PXM.a>runrev 2 3.0(20.0)

The active card resets and the standby card takes over as active. Both cards are running the new revision.

Step 5 When the standby card is in STANDBY again, enter the abortrev <standby slot> <image version> command to abort this upgrade if needed, as in the following example:

ses1.1.PXM.a>abortrev 1 3.0(20.0)

Step 6 Enter the commitrev <standby slot> <image version> command to commit the new version of the runtime image of the controller card, as in the following example:

ses1.1.PXM.a>commitrev 2 3.0(20.0)

Step 7 Enter the dspcd command to verify a successful upgrade.

ses1.1.PXM.a>dspcd 1
ses1.1.PXM.a>dspcd 2


Upgrading the Runtime Image on Non-Redundant Systems

The upgrade of the runtime image on the a non-redundant controller card is non-graceful. That means the traffic is disrupted on the card during this operation.

For non-redundant systems, follow these steps.


Step 1 Use FTP to transfer the runtime image to the card disk.

a. At the SES CLI, enter the dspipif command at the active controller card to find the node's IP address. The field internet address for lnPci 0 interface is the node IP address.

b. From the workstation containing the PXM backup boot image, enter ftp <Node IP address>.

c. Enter the username cisco.

d. Enter your password.


Note The default password is 1ciscoinc. If you have changed the default password to a new password, use your new password.


e. Enter the cd C:/FW command to get to the switch directory.

f. Enter the bin command (for a binary transfer).

g. Enter the put <runtime image name> command to transfer the runtime files from the server to the switch directory C:/FW. See the following example:

put pxm1_003.000.020.000_ses.fw

h. Enter the bye command to end your session.

Step 2 Set the new version of the runtime image on the controller card as in the following procedure:

a. Enter the loadrev <slot> <image version> command as in the following example:

ses1.1.PXM.a>loadrev 1 3.0(20.0)

Note No cards will reset.


b. Reply Y (yes) to the proceed question.

c. Enter the dspcd command in the following example:

ses1.1.PXM.a>dspcd 1

The secondary revision on the PXM is set to new image version.

Step 3 Enter the runrev <slot> <image version> command to run the new version of runtime image on the controller card.

ses1.1.PXM.a>runrev 1 3.0(20.0)

The card will reset and run the new revision when it returns.

Step 4 Enter the dspcd command to verify a successful upgrade.

ses1.1.PXM.a>dspcd 1
ses1.1.PXM.a>dspcd 2

Step 5 At this point, you can still abort this upgrade if needed. To abort the upgrade, enter the abortrev command.

ses1.1.PXM.a> abortrev 1 3.0(20.0)

Step 6 Enter the commitrev <slot> <image version> command to commit the new version of the runtime image of the controller card.

ses1.1.PXM.a> commitrev <slot> <image version>

ses1.1.PXM.a> commitrev 1 3.0(20.0)

Step 7 Enter the dspcd command to verify that the runtime image is correct on the card.

ses1.1.PXM.a> dspcd 1


Upgrade Path

Release 3.0.20 supports upgrades from Release 1.0.15, Release 1.0.16, Release 1.1.75, Release 3.0, and Release 3.0.10. If you are running a release prior to Release 1.0.15, you must upgrade to Release 1.0.15 before you can upgrade to Release 3.0.20.

Cisco SES PNNI Controller Bring Up Procedure

Limitations and Restrictions

The following sections describe issues in this release:

General Limitations and Restrictions

Recommendations

General Limitations and Restrictions

The following list describes limitations and restrictions that apply to this release:

A graceful upgrade can only be completed from the SES controller software Releases 1.0.15, 1.0.16, 1.0.75, 3.0, and 3.0.10.

The number of connections is always less then the max con value used in the addpart command. This is due to the fact that each card needs 1 LCN for control VC. If your network is a PNNI network, there is another VC for RCC. Therefore, if the max con value is set to 9000 connections, only 8999 or 8998 connections can be added.

The dspcons command does not support ranges for VPI/VCI. If you enter dspcons -vpi 2, all SPVCs with a VPI less than and equal to 2 are displayed; not just the SPVCs with a VPI equal to 2.

The Route Optimization algorithm is node-by-node and is based on connection mastership. It is not distributed across the node. For example, if Node A is connected to Node C via Node B, Node A only knows about the connections from A to B, and not about the connections from B to C. This limitation does not allow Node A to use route optimization for connections from B to C.

There is no check for preventing multiple masters of SPVC connections from pointing to the same slave. When provisioning a second connection to a slave VPI/VCI that is already used, there will be no CLI warning that the connection has failed.

In a large network, it can take up to 30 seconds (or more) to accept new calls after a switchover. This is because PNNI relearns the topology on a switchover. For existing connections, the control plane and the data plane are not affected on a switchover.

Node names are not required for each node. A node name can be entered and distributed, but there is no check for node name uniqueness within the network. Multiple nodes with the same name do not cause inconsistencies in PNNI routing.

BXM interface (OC and T3) traffic policing only works if the cell rate is higher than 50 cells per second.

When the master endpoint is deleted on a DACS SPVC connection, the slave endpoint is also deleted.

The following limitation is in the BXM firmware release MFL and all the releases that follow: due to limited memory space on the BXM card and increased code size, channel statistics level 0 is no longer supported on BXM cards (BXM-155-4, BXM-155-8, BXM-622, BXM-622-2, BXM-T3-8, BXM-T3-12, BXM-E3-8, BXM-E3-12 models). When the BXM card firmware is upgraded to MFL or any post MFL release, regardless how many connections are provisioned, channel statistics level 0 is no longer supported. If a BXM card has channel statistics level 0 turned on, use one of the following upgrade paths to upgrade BXM firmware to MFL or any post MFL release:

Change the BXM card to run channel statistics level 1. Statistics level 1 supports a maximum of
16 K connections on a card. If a card has more than 16 K connections configured, some connections must be relocated to other BXM interfaces to reduce the total number of connections to be less than 16 K. Reset the card after changing to statistics level 1.

Upgrade the BXM card to the BXM-E card. The BXM-E card can continue running statistics level 0. Statistics level 0 can support a maximum of 32 K connections on a card.

Recommendations

The following recommendations apply to Release 3.0.20 of the SES controller:

SPVC connections are provisioned according to a two-ended provisioning model, similar to the way connections are provisioned using AR. This provisioning model enables more robust management (including fault conditions) of both connection endpoints, as opposed to a model which only provisions the master endpoint.

In order to establish a double-ended DACS or a double-ended routed SPVC, provision the slave endpoint before provisioning the master endpoint. The traffic parameters and QoS parameters on both the master and slave endpoints must match in order to establish an SPVC. To establish a single-ended SPVC connection, you only need to provision the master endpoint.

For each SPVC addition, deletion, or modification, the SES controller generates a trap to CWM. This trap enables CWM to sync up its connection management database with the BPX SES node in real time. The trap information exchange between CWM and SES is handled by an inter-system communication protocol. The trap-handling rate is much slower than the script driven SPVC setup or delete rate. When you use a script to do burst SPVC addition or deletion, the trap queue may overflow and cause trap loss due to limited trap queue size. If burst SPVC add and delete size is more than 1 K connections, Cisco recommends that you pace your setup and delete rate to be 1 connection per second to avoid trap loss.

The minSvccVci value for the partition is defaulted to 35. VCI 33 and 34 are marked for future control plane use.

In the case of obtaining optimized routes while performing PNNI on demand route lookup, Cisco recommends that you change the routing policy to the best fit option

CSCdx60401

Symptom:

Node continuously resets.

Conditions:

Node is receiving hello packets at line rate on a PNNI link

Workaround:

None

CSCdz43804

Symptom:

IP Ethernet for MGX 8950 and SES are not accessible.

Conditions:

Power outage.

Workaround:

Unknown.

S2 BUGS

 

CSCdz32385

Symptom:

SVCC RCC does not get established even when resources are available on one of the common outside links.

Conditions:

The common outside link that came up first does not have enough resources.

Workaround:

Down the common outside link with no resources and up it again.

S3 BUGS

 

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 delcons command 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.

CSCdz27235

Symptom:

pnccb takes lot of CPU time while derouting connections.

Conditions:

MGX8850 and PXM45/B

Workaround:

Under investigation.

CSCdz32647

Symptom:

NNI links stuck in building vc state.

Conditions:

Ran 2 scripts to reset SMs and up/dn ILMI on all ports.

Workaround:

N/A.

S2 BUGS

 

CSCdy36366

Symptom:

MPG SPVC cost should include cost of traversing via peer groups.

Condition:

Only includes cost of higher level Hlinks, and source PG cost. Since the via peer group costs are not included, it's possible that we might not take a more optimized route during route optimization.

Workaround:

None.

CSCdy44919

Symptom:

Assigned route cost incorrectly calculated resulting in abnormally low route-cost via dspcon on the PXM45. Also affects potential use of optrte when comparison of costs is performed.

Conditions:

Occurs during "On-Demand" route events, on CBR and/or VBR connections which have CTD and or CDV configured from non-default values and "Best-Fit" is configured for On-Demand routing policy with the command cnfpnni-routing-policy.

Workaround:

Using rrtcon when the pre-calculated route is available will assign a valid Route cost however the potential still exists for another abnormally low cost to be assigned on the next On-Demand routing event. Disabling "Best-Fit" by using "First-Fit" or configuring CDV or CTD values back to defaults of -1 will disrupt the condition and result in the correct calculation of route cost again during On-Demand.

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 (for example, 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, and so forth.

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 bw. 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.

Condition:

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

Workaround:

None.

CSCdy82185

Symptom:

error while executing core command on SES

Conditions:

MGX8830 PXM1 3.0(10.0)

Workaround:

Under Investigation

CSCdy86129

Symptom:

Routing cost are not getting updated properly.

Conditions:

When downing a pnport to cause the re-route.

Workaround:

none

CSCdy88938

Symptom:

Active PXM45 reboots after issuing the aesa_ping <aesa> -qos -abr command.

Conditions:

Normal operating conditions. Above command is used.

Workaround:

Do not use the aesa_ping command with the -qos abr switch.

CSCdz35390

Symptom:

PXM1 card stuck in init state during upgrade

Conditions:

An interim SES engineering version.

Workaround:

Under investigation.

CSCdz35621

Symptom:

Connections do not get routed to a slave node in a different PGL since the remote node's summary address rule is being advertised as a scope of 56 (instead of 0).

Conditions:

An interim SES engineering version.

Workaround:

Switchcc on the PTSE originating node (slave node) so that the node re-sends the PTSEs and the scope of the PTSE is corrected to 0.

CSCdw03688

Symptom:

Software error on handler when executing the runrev command while upgrading.

Condition:

48k DACS SPVCs and 11k routed SPVCs on the SES-BPX node.

Workaround:

None.

CSCdx35791

Symptom:

PXM45 fails to come up. If it were a standby PXM45, the dspcds on the active PXM45 indicates that the standby PXM45 slot is empty. Output from the debug console shows junk characters.

Condition:

When the PXM45's console port is connected through a terminal server with echo mode turned on, junk characters come in into the console port of the PXM45. When this card is reset, the runtime image stops its initialization when it received these junk characters on the console port.

Workaround:

1. Configure the terminal server to disable the echo mode.

2. Alternatively, pull out the console port cable and reset the card.

CSCdy51972

Symptom:

False channel alarms got stuck after switchyred on BXME.

Conditions:

FW upgrade of BXME cards to MFP caused a line alarm. The customer tried a switchcc on the SES controller to clear the line alarm. This caused false channel alarms. The customer then tried a switchyred to clear the false channel alarms faster. This made the false channel alarms stay. The customer had to reset the FRSM cards to clear the alarms.

Workaround:

Reset the FRSM cards on the MGX(8220) or don't switchyred on the BXME while there are false channel alarms. The false channel alarms would clear in about 30 min.

CSCdy59180

Symptom:

Once it was observed that 4 SPVC failed to route. This failure was due to slave state of the connections were in the wrong state.

svc-rcc does not come up.

Conditions:

After a switchcc is done on the PGL node.

Workaround:

None.

CSCdw61915

Symptom:

Event logged specified incorrect time data by LMI. Date is being set by BPX on SES feeder.

Conditions:

A new field was added to time structure. This field is not initialized by LMI and can take various values. Under certain conditions, this value is in error and causes the event to be logged.

Workaround:

None.

CSCdx78946

Symptoms:

MGX 8230/ SES dspsigstats shows "Connect Ack" Messages on AINI SES 1.1.75.103

Conditions:

The configuration is: - 2 SES connected via an AINI. - One SPVC configured with Master endpoint on one SES and Slave endpoint on the other. The problem is that according to ATM Signalling standards the "CONNECT ACK" message only exists in UNI Signalling. It does not exist in AINI. AINI implementation generates a CONNECT ACK message and as a result does not conform with the ATM Forum specification af-cs-0125.000.

Workaround:

Unknown.

CSCdx60401

Symptom:

Node continuously resets.

Conditions:

Hello packet flooding at line rate.

Workaround:

Unknown

CSCdw03688

Symptom:

Software error on handler when executing runrev while upgrading.

Conditions:

48k DACS SPVCs and 11k routed SPVCs on the SES-BPX node.

Workaround:

None.

CSCdx35791

Symptom:

PXM45 fails to come up. If it were a standby PXM, the dspcds on the active PXM indicates that the Standby PXM slot is empty. Output from the debug console shows junk characters.

Conditions:

When the PXM45's console port is connected through a terminal server with echo mode turned on, junk characters come into the console port of the PXM45. When this card is reset, the runtime image stops its initialization when it received these junk characters on the console port.

Workaround:

1. Configure the terminal server to disable the echo mode.

2. Alternatively, pull out the console port cable and reset the card.

CSCdw51798

Symptom:

S-PVC Calling/Called PVCC IE is not be corrected encoded.

Conditions:

PNNI conformance test failed under section R3.1.1.4/R3.1.1.5 The following test verifies the initiating PVPC/PVCC establishment procedure as outlined in AF-CS-0127.000 Section 9.2.1 and PICS conformance as described in ATM Forum AF-CS-0127.000 PNNI SPVC Addendum Version 1.0, July, 1999 and ATM Forum AF-CS-012@7.000PNNI SPVC Addendum Version 1.0, July, 1999.

Workaround:

None.

CSCdw57706

Symptom:

The VCI values are given with a value of "0" for the Calling and Called Party Soft PVPC or PVCC Information Element. The requirement states that this octet - VCI is only present in case of a soft PVCC.

Conditions:

Called/Calling Soft PVPC or PVCC Information Element as described in Section 6.4.6.1 and Section 6.4.6.2 of AF-CS-0127.000.

Workaround:

None.

CSCdw64939

Symptom:

BPX-SES is responding with an incorrect Cause 43d rather than 100d when a SETUP message is received with an "access information element" with invalid content. Per Non conformance to Q2931 para. 5.6.8.2.

Conditions:

None.

Workaround:

None.

CSCdw74433

Symptom:

PNNI conformance test failed in Q2931 para 5.6.8.2, When a SETUP message is received with invalid length in a non-mandatory IE, The BPX/SES is not taking action on the call.

Conditions:

Running a test suite.

Workaround:

None.

CSCdx32349

Symptom:

SES did not add SPVC endpoint.

Conditions:

None.

Workaround:

None.

CSCdx40378

Symptom:

When sending F5 OAM end to end flows through a DACS SPVC, only the "egress" counters of dspconstats increment. This true for F5 end to end AIS, or F5 end to end loopback.

Conditions:

None.

Workaround:

None.

CSCdx40400

Symptom:

When the tstdelay command is entered on an SPVC on the SES, the "Cells sent total local egress" counter increments, which suggests that a tstdelay (which measures delay inside the network) results in cells being sent over a UNI, outside of the network (that would be wrong). However, using an HP BSTS to monitor traffic on the other side of the interface, it is clear that no cells are sent. So the counter increment is bogus.

Conditions:

None.

Workaround:

None.

CSCdx45385

Symptom:

On the SES, the dsppnportrsrc command is used to check the available VSI resources on a port. Testing shows that dsppnportrsrc keeps aligned with the exact state of VSI resources when an SPVC endpoint is added to the port. However, the dsppnportrsrc display is not updated following a change of the VSI resources done using the cnfrsrc <slot.port> command on a BPX. This is especially troublesome when a port runs out of LCNs. The dsppnportrsrc command display shows "# Avl Tx Chans:" = 0. After going on the BPX and increasing the size of the VSI partition, the dsppnportrsrc command display still shows the number of available LCN as being 0, so the SES will reject any provisioning attempt on that port, even though there truly are resources available to accept the SPVC endpoint.

Conditions:

Following are screenshots of an example triggering of the problem:

On the BPX, on a BXM-T3-12 card, up a single port. The card must have only port (to facilitate VSI management). The bug also happens with more than one port.

Configure the port as follows:

Up the port.

Enable a VSI partition on the port, with overlapping VPI range, half the BW and min VSI LCN = 0, Max VSI LCN = 1. cnfvssiif <slot.port> 2 cnfrsrc.

On the SES, do a dsppnportrsrc and check the number of available LCNs as seen by the SES (the UNI Signalling Channel is disabled, "cnfpnportsig 3.1 - univer none."

On the BPX, increase the number of Max VSI LCNs from 1 to 5.

On the SES, dsppnportrsrc still shows 1. This never gets updated it seems

Provision an SPVC endpoint against that port. That gets dsppnportrsrc to be updated to the correct value (4).

Provision 4 additional SPVC endpoints against that port. This exhausts the VSI LCNs on the port and gets dsppnportrsrc to show "0."

On the BPX, via cnfrsrc, increase the Max VSI LCN for the port from 5 to 10.

Check dsppnportrsrc on the SES. It still shows 0 available LCNs for nrtvbr.

As a result the SES rejects a provisioning attempt for nrtvbr SPVC endpoint on that port.

On the BPX, increase Max VSI LCN for that port from 10 to 15.

On the SES dsppnportrsrc is still not accurate and still maintains a discrepancy between nrtvbr and other ATM Service Categories.

Workaround:

None.

CSCdx76273

Symptom:

The cnfqosdefault command is unusable and does not provide what the ATM Forum specifications intended. The cnfqosdefaut command should be port-specific and NOT node-wide.

Conditions:

SES is running 1.1.75.103.

Workaround:

None.

Symptom:

Given a redundant SES node, pull out the trunk back-card from the active PXM's slot. This causes the active PXM to reboot and the standby PXM to take over as the active front-card. The previously-active PXM card should come up as the standby card but instead, it keeps rebooting.

Conditions:

Not known as yet. It is suspected that some task is trying to access the NOVRAM on the (absent) trunk back-card.

Workaround:

None. The only thing to do is not to pull out the trunk back-card while the front-card is either in the active or standby role.

CSCdu19130

Symptoms:

After entering the abortrev command on one node in the network, the other node with 50 K routed connections crashed. It did not respond to certain CLI commands, such as dsppnports and dspcons.

Conditions:

There are 50 K routed connections between node pswpop7/pswbpx2 and orses18/svcbpx23 via node pswpop6/pswbpx6. I entered the loadrev and runrev commands to upgrade the orses18 node from 1.0 to 1.1. Everything was fine after upgrade. I then entered the abortrev command to bring the orses18 node back to the 1.0 image. After entering the abortrev command on the pswpop7 node, it suddenly crashed; many tasks were deleted. The pswpop7 node did not respond to some CLI commands, such as dsppnports, dspcons, and dspconinfo. However, the dspdate, dsplogs, and dsperrs commands worked fine.

Workaround:

None.

CSCdu22913

Symptoms:

The SSI_SRAM_WIN_TIMEOUT Redman Error caused the standby PXM reset.

Condition:

There were about 50 k routed SPVC connections between two Orion/BPX nodes. One Orion node had redundant PXM cards. I pulled out the Y-cable on the feeder trunk. The RedmanError SSI_SRAM_WIN_TIMEOUT caused the standby PXM to reset.

Workaround:

Unknown.

CSCdu24540

Symptoms:

After running the script to dncon/upcon on an SES node, the dbsvr command failed to upgrade after the standby PXM reset.

Conditions:

CSCdt78006

Symptoms:

Connections went into mismatch after replacing the PXMs in a node and entering the switchcc command.

Conditions:

A customer was going through an exercise of replacing PXMs on their nodes. On two nodes, the standby PXM was replaced, and the switchcc command was entered to make the new PXM the active one. Connections went into mismatch state for a short while, and then cleared. We were not able to get into the node to collect information while this condition existed.

Workaround:

Unknown.

CSCds74052

Symptoms:

I pulled out the trunk back-card from the active PXM's slot on a redundant SES node. This caused the active PXM to reboot and the standby PXM to take over as the active front-card. The previously-active PXM card should have come up as the standby card, but it kept rebooting.

Conditions:

Unknown. It is suspected that some task is trying to access the NOVRAM on the (absent) trunk back-card.

Workaround:

Technical Assistance Center

The Cisco Technical Assistance Center (TAC) is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Cisco TAC inquiries are categorized according to the urgency of the issue:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:

http://www.cisco.com/register/

If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC Web Site, you can open a case online by using the TAC Case Open tool at this URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.

When you call the center, please have available your service agreement number and your product serial number.
