MGX-VXSM-T3 Card

Release 5.2.00 introduces a third VXSM card for the support of T3 lines. The card consists of a front card with six T3 ports and a half height back card with three T3 ports. The front card can be configured with either a single back card or two back cards.

AXSM-8-622-XG Card

The AXSM-8-622-XG is an 8-port OC-12/STM-4 card that supports clear-channel OC-12c/STM-4 or OC12/STM-4 channelized down to OC-3c/STM-1 and DS3. This card complements the family of AXSM-XG cards, which includes the AXSM-16-155-XG, AXSM-4-2488-XG, and AXSM-1-9953-XG.

The AXSM-8-622-XG card has the following functionality:

•Independent channelization of each line.

–Supports all feeder functions available with AXSM and AXSM/B cards.

•BPX product support

The AXSM-8-622-XG supports direct connection to BPX nodes with all ENNI functions available on AXSM and AXSM/B.

The AXSM-8-622-XG card has the following restrictions:

•All lines on the same bay must have the same SONET/SDH configuration

•Up to 1 ms of traffic loss after reconfiguration of lines/paths on the same bay

•The AXSM-XG does not support AutoRoute CoS queues

Graceful Upgrades to AXSM-XG Cards

In this release, you can gracefully upgrade AXSM, AXSM/B and AXSM-E cards to AXSM-XG cards. The AXSM-16-155-XG and AXSM-8-622-XG cards have a higher port density than the equivalent AXSM-E cards, and the AXSM-16-155-XG and AXSM-8-622-XG have better traffic management support than their AXSM/B counterparts.

Graceful upgrades simplify the process of migrating to the newer AXSM-XG cards. During the upgrade, the MGX control processor transfers the configuration/connection database from the previously installed AXSM card to the new AXSM-XG, which preserves all connection configurations. The upgrade process might cause an outage of up to four minutes.

You can install and operate any number of AXSM-XG cards in conjunction with AXSM, AXSM/B or AXSM-E in an MGX 8850 chassis equipped with the PXM45 processor. You can install and operate any number of AXSM-XG cards in conjunction with AXSM/B in an MGX 8950.

Card redundancy is supported only between identical front and back card pairs. For example, an AXSM-16-155-XG can only be redundant to another AXSM-16-155-XG, where the two front cards use an identical set of back cards.

For more information about the upgrade procedure, see the "Upgrading an AXSM/A, AXSM/B, or AXSM-E to an AXSM-XG" section.

Multilink PPP on the MPSM-T3E3-155 Card

This release adds Multilink PPP (MLPPP) to the MPSM-T3E3-155 card. MLPPP includes the following capabilities:

•Support for MLPPP

•PPPmux on a MLPPP bundle basis

•Interworking between MLPPP and PPPoATM

•NxDS0 and DS1 PPP links

•Maximum of 84 PPP links per card

•Maximum of 84 MLPPP bundles per card

•Maximum of 6 PPP links per MLPPP bundle

•Dynamic (auto) PVC bandwidth on a MLPPP bundle basis

•Layer 2 QoS to minimize delay of delay sensitive traffic and prioritize control messages

•Support for three strict priority queues

•Support for the CDMA2000 and EVDO

•1:1 hot standby front card redundancy

•Operational load management

The MLPPP feature has the following restriction:

•Supported on the BNC-3-T3E3 back card only and only in channelized mode. In other words, MLPPP is not supported for E3 in any form or unchannelized T3.

PXM45/C Support in the MGX 8830/B Chassis

A PXM45/C controller in an MGX8830/B chassis provides support for a selection of narrowband and broadband interfaces in an 8-slot chassis. The PXM45/C controller's 45Gbps switch matrix makes it possible to aggregate and switch traffic from a mix narrowband, DS3/E3, OC3c/STM-1 and OC12/STM-4 ATM ports, and simplifies the process of scaling a network node as connection counts increase.

Mobile PNNI Support

This release adds the Mobile PNNI feature to the existing PNNI functionality. Generally a PNNI network has a fixed hierarchy where each element has a fixed point of attachment. Mobile PNNI extends a fixed network infrastructure to mobile ATM switches that are roaming in the network. To maintain connectivity when the location of the mobile ATM switch changes, mobile switches are allowed to dynamically change peer group membership. To implement this feature you simply establish a link to the fixed network; the mobile network then finds the proper peer group and hierarchy and joins the network.

Mobile PNNI allows each mobile network to build its own PNNI hierarchy and integrate the hierarchy of the fixed network as a logical group node (LGN). In the context of mobile PNNI, it is called Mobile LGN. A mobile logical group node has the capability to dynamically change its membership from one peer group to another as it attaches to different fixed switches. A mobile logical group node is only allowed to join a parent peer group of one of the fixed switches.

The ATM forum describes mobile PNNI in publication AF-RA-0123.000, PNNI addendum for mobility extensions version 1.0, which is available at the following location:

ftp://ftp.atmforum.com/pub/approved-specs/af-ra-0123.000.pdf

Compression and Multiplexing Support for RPM-PR Cards

The MGX-RPM-1FE-CP (one-port, Fast Ethernet-Co-processor) back card is an MGX8850/RPM-PR back card that off-loads the following processes from the Route Processor Module (RPM-PR):

•Compression/decompression of Real-time Transport Protocol (RTP)/User Datagram Protocol (UDP) headers (cRTP/cUDP)

•Multiplexing/demultiplexing of Point-to-Point Protocol (PPP) frames

This feature was previously supported on PXM1 systems only. This release extends this capability to PXM1E/PXM45 systems.

Multilink PPP Feature for CDMA2000 and EVDO

The MPSM-16-T1E1 implements Multilink PPP, which is a key protocol in a larger application defined by CDMA2000. In this application, the MGX 8850 (PXM45) aggregates traffic from several BTS site routers (MWR) and transfers that traffic to an IP network. The aggregation point in the MGX 8850 (PXM45) is the RPM-XF. Traffic from all of the BTS routers are transported over PPP links (typically on T1/E1 links) and brought into the MGX 8850 (PXM45) through an MPSM-16-T1E1 card. The MPSM-16-T1E1 transforms the PPP payload into AAL5 cells, which it sends to the RPM-XF using ciscoPPPoAAL5 encapsulation.

With growth in traffic in the CDMA2000 application, you might need to add additional T1/E1 links between the MWR and the MPSM-16-T1E1. The MLPPP feature simplifies the process of adding incremental bandwidth because it can aggregate capacity of individual T1/E1 lines. Because the IP payloads are small (typically voice) and the overhead associated with PPP (MLPPP) packets increases with smaller payloads, PPPMUX functionality is utilized on the MPSM-16-T1E1. In EV-DO, multiplexing is not utilized.

The connection between MPSM and RPM-XF is setup as a PVC connection. The bandwidth of this PVC depends on the number of operation PPP links on an MP bundle. RPM-XF terminates the PPPoAAL5 data and routes the IP traffic to the backbone IP network.

MPSM-155-T3E3 and MPSM-16-T1E1 Online Diagnostics

The online diagnostic tests run on regular intervals for both on the active and standby state of the MPSM cards to check the health of the devices and data paths. The online diagnostics test the following devices and data paths:

•Data path from the CPU on the MPSM to the CBC slave loopback on the MPSM via Winpath 0

•Data path from the CPU on MPSM to the CBC master loopback on the PXM via Winpath 1

•Winpath memory access test (packet, parameter, host memory)

•Write/read memory access test for internal devices

•Validate front card NVRAM checksum

•Validate flash checksum

PNNI Current Route Feature

Current Route feature provides the path information for active Point-to-Point (P2P) SPVCs/SPVPs master-end connections. The path information contains the lowest level physical node and egress trunk information of the path on which the connection is currently routed.

This feature utilizes the ATM standards based connTrace message to obtain the current route information. CWM uses the configuration upload file mechanism to request available path information of connections on a periodic or an on-demand basis.

This feature works in single peer group and multiple peer group networks. The current path can be used by the network administrators and planners to engineer the trunk usage and to direct how connections should be routed.

Operational and Redundancy Limitations

The current route feature has the following operational limitations:

•Point-to-multipoint calls are not supported.

•Only SPVC/SPVP connections are supported. CWM does not manage SVC/SVP connections.

•Master ended connections have the current route information. Slave ended connections do not have this information.

•The configuration upload file contains a snapshot of the current route information at the time that the switch receives a configuration upload request from CWM. Therefore, the snapshot might not contain the latest information, and connection trace information that the switch receives after the file is created is not included in the file.

•If congestion occurs on a node, the connTrace message sent by the CLI and by the Current Route feature is dropped. The two connTrace messages are not distinguishable. This limitation also applies to connTrace ACK messages that are received on a congested node.

•After changing a node ID, disable and then re-enable the current route feature on each node in the network using the new CLI command, cnfndcurrte.

This command flushes all existing current route information and starts collecting new information. After disabling the current route feature, wait at least 9 seconds (the time-out period for a connTrace message) before re-enabling it. This inhibits processing of stale connTrace messages.

•The connection path information for a connection traversing more than 20 nodes is not stored in the current route path table. Therefore, such connections do not have current route information.

•The current route path does not include the destination termination port (normally slave endpoint UNI port). The destination port is set to zero in the current route path, which is similar to preferred route.

The current route feature has the following redundancy limitations:

•The current route feature provides redundancy. However, because the current route must not reduce routing performance, some connections might not have redundant current route information on the standby PXM.

For those connections that do not have redundant current route information at the time of a switchcc, their current route information is obtained through the normal scanning on the active card when the old standby becomes the new active.

•After a standby PXM card is inserted and reset, the active card sends the current route information to the standby card only after its state changes from Init to Standby. This avoids increasing the time it takes for the redundant card to come up to the Standby state, ready for switchcc.

The Standby state is not redundant until the current route update is completed. Therefore, a switchcc that occurs before all current route information is sent to the redundant card results in some connections not having current route information on the newly active card. The current route information for those connections is obtained during the normal current route scanning and processing.

•When inserting or resetting the standby PXM, enter the command dspndcurrte and verify that Bulkupdate is complete before performing a switchcc.

Feature Specifications

The current route feature has the following limits:

•A maximum of 10K path entries per node are supported.

•A maximum of 5K node ID entries per node are supported.

•A maximum of 2K ports on PXM1E systems are supported when current route is enabled.

An attempt to enable the current route feature on a node which has more than 2K ports is not allowed and results in error. If the current route feature is enabled and more than 2K ports are subsequently added, this feature or other applications might not work properly.

•A maximum of 100K connections are supported PXM45/B systems when current route is enabled.

An attempt to enable current route on a node which has more than 100K connections results in error. If the current route feature is enabled and more than 100K connections are subsequently added, this feature or other applications might not work properly.

PNNI Product Enhancements

The Link Selection enhancement adds new functionality to parallel links to which link selection criteria is provisioned to `minAW' (`minAWlinks'). This feature can be activated through the CLI. If these enhancements are not activated, the existing `link selection' behavior preserves.

Table 1 lists the PNNI product enhancement requests incorporated in this release.

Table 1 PNNI Product Enhancement Requests Incorporated 

PER ID	Description
PER 5672	SVCC-RCC connection configuration This enhancement introduces a command (cnfpnni-svcc-rcc-param) to configure the connection parameters associated with SVCC-RCC connections at each level of the PNNI hierarchy.
PER 8281	Path bypass selection configuration In a complex node multiple peer group topology, the path that has the highest available cell rate (AvCR) is advertised as the bypass. Typically this path has higher cost, so the calls routed over the pass bypass might always take the worst path. This enhancement adds an option to the cnfpnni-routing-policy command to specify the criteria for bypass path selection.
PER 8282	Administrative Weigh (AW) Pruning Currently a trunk is included in the best path selection even if it has a single cell per second of AvCR. This enhancement introduces an AvCR threshold parameter to the cnfpnni-routing-policy command so that trunks with BW below the threshold are excluded from the best path search.
PER 8287	Consistent PNNI Link Selection Allows application of the same link selection mechanism to connections of all service categories (ABR, UBR, CBR and VBR) on `minAW links'. Allows provisioning `epsilon-equal AW parallel links' among the `minAW parallel links' between two switches. The switch calculates the `epsilon' value based on user inputs. If `epsilon-equal AW parallel links' exist between two switches along the selected shortest path, `link selection' applies. For `epsilon-equal AW parallel links', the secondary `link selection criteria' is maxAvCR. If all links have the same AvCR, the connections are routed according to load balance criteria.
PER 8540	Preferred Route Enhancements The cnfndidrtes command has a new parameter for indicating that the same node is being configured and that the preferred route status should not change. A connection that was on a preferred route before the change would not be groomed by route optimization.
PER 8660	Link Selection Enhancements for MPG (multi-peer group) Pref Rt Conns
PER 8807	Routing Policy Enhancements This enhancement adds a parameter value to the cnfpnni-routing-policy command that selects from equal administrative weight (AW) paths using the number of minimum hops. If multiple epsilon-equal AW paths with the same minimum-hops exist, a second load balance parameter specifies the tie-break criteria.

PXM1E OAM Enhancement

The PXM1E processes the following OAM loopback cells:

•End-to-end OAM loopback cells —Used for background connection continuity verification. These cells might be sent by a VISM card or router.

•Segment OAM loopback cells— Used for diagnostic testing between segment endpoints. These cells are sent for the following CLI commands: tstdelay, tstconsegep, and tstpndelay.

This release moves the task of extracting and injecting OAM loopback cells at the PXM1E from the Atlas to the QE1210. Unlike with Atlas, the QE1210 can distinguish between segment and end-to-end OAM loopback cells. The QE1210 extracts only the segment OAM loopback cells, while transparently passing the end-to-end OAM loopback cells.

Because the end-to-end OAM loopback cells no longer require software processing, the previous limitations for the OAM loopback cell rate on the PXM1E no longer apply. These cells are now processed in the QE1210 hardware and are limited only by the available line bandwidth.

Each PXM1E segment endpoint has a polling-induced queue extraction delay of up to 10 ms for a segment OAM loopback cell. This delay is not imposed on end-to-end cells or segment cells at non segment endpoints.

IP Management Connections through the RPM

You can manage the MGX 8850 node from the traditional Ethernet or console port, or you can set up one of the following connections:

•Through the AXSM or MPSM cards using an SVC to the PXM card

•Through the RPM card using a PVC to the PXM card

This release changes the PXM svcifconfig command to support management connections through the RPM card.

The IP addresses of hosts accessing the MGX 8850 node are stored in a RAM cache. Because this cache has a limit of 50 entries, only 50 IP hosts can actively access the node at one time. New IP hosts are blocked until the cache clears (as result of inactivity from some hosts) to make room for new entries.

Use this solution to manage only one MGX 8850 node through RPM, not an entire network of nodes.

---

Note If you are connected to the MGX node using the RPM and accidentally delete the SPVC, the connection drops. To restore RPM access, you must re-add the SPVC using the console port or Ethernet port.

---

---

Note If the clrallcnf, clrcnf, or clrsmcnf commands are executed, the persistent data pertaining to the IP connections is lost and connections are dropped. To restore RPM access, you must reconfigure the RPM and PXM cards for IP connectivity, using the console port or Ethernet port.

1 APS connectors are not required in 8830 chassis. 2 The FRSM-12-T3E3 card is not supported.

Table 8 presents a guide on which APS connector to use with which MGX chassis and front card.

In these tables:

•R- means that this is a redundant card, for AX-R-RJ48-8E1, AX-R-RJ48-8T1, and AX-R-SMB-8E1 cards.

•Either of these connectors work for the AXSM cards in the MGX 8850 (PXM45) switch: MGX-8850-APS-CON or MGX-APS-CON.

•The PXM45 card is not supported in Release 5.0.00 and higher. The PXM45/B and PXM45/C cards are supported.

•The SCSI2-2HSSI/B card has two different 800 part numbers, and both part numbers are valid.

•The PXM1E-COMBO card is also known as PXM1E-T3E3-155 card.

MGX 8950 does not support the AXSM/A or the AXSM-E cards. If these cards are present, they will show up as "Failed" when the dspcds command is issued.

Limitations, Restrictions, and Notes

This section includes information about limitations, restrictions, and notes pertaining to MGX Release 5.2.00.

PXM1E Switch Limitations

The following notes apply to PXM1E based switches—MGX 8850 (PXM1E) and MGX 8830:

•Y-red is not supported on the MCC Electrical back card.

•For inter-card APS to work on the PXM1E-8-155, and one front card is missing or not available, both back cards must be present. A front card cannot drive the alternate trunk back card when its own local trunk back card is absent.

•MPLS controller is not supported on PXM1E.

•PXM1E clock source is supported by VISM-PR, CESM, and AUSM cell bus service module cards. CESM and AUSM can provide one clock source, either primary or secondary.

•Only SPVCs and SPVPs are supported on cell bus service modules. SVCs are not supported on CBSMs.

•No bandwidth CAC support exists on the cell bus service modules, except for the RPM card, which is checked against the OC-3 card rate. For example, for a given RPM, the bandwidth allocated to all connections might not exceed the OC-3 rate. Bandwidth CAC is supported on the PXM1E uplink port.

•The maximum bandwidth to be distributed among cell bus service modules is approximately an OC-10 rate while traffic on the network interfaces on PXM1E can achieve true OC-12 line rate.

•Traffic must be balanced between the cell bus controllers to achieve the OC-10 rate. The traffic must 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 is dropped. However, if only one cell bus controller is used and the other cell bus controller is not used, then it can achieve an OC-10 rate. On an MGX 8850, the CBCs are split between the left and right side of the chassis: CBC0 supports slots 1-6 and 17-22 and CBC1 supports slots 9-14 and 25-30. On an MGX 8830, CBC0 supports slots 3,5,10, and 12 and CBC1 supports slots 4,6,11, and 13. Balance is achieved by planning the distribution of your cell base card by evenly distributing from the left side of the chassis and the right side of the chassis.

PXM1E Hardware Limitations

PXM1E hardware limitations are as follows:

•For inter-card APS to work on the PXM1E-8-155 with one front card missing or unavailable, both back cards must be present. A front card cannot drive the alternate trunk back card when its own local trunk back card is absent.

•During hardware upgrade from PXM1E-4-155 to PXM1E-8-155, at the time when the inserted card types are different (one PXM1E-4-155 card set and one PXM1E- 8-155 card set), the standby trunk back card functionality is not available. Therefore, LED functionality is not available, and APS lines do not work on that backcard. Modular optical transceiver (SFP-8-155) mismatches are not reported for that backcard, and SFP-8-155 mismatches are not reported during hardware upgrades.

•Because the PXM1E-4-155 and PXM1E-8-155 back cards support LC and SC interfaces respectively, the following restriction applies when upgrading from PXM1E-4-155 to PXM1E-8-155 hardware:

After replacing the first PXM1E-4-155 card with the PXM1E-8-155 card set, update cabling for the PXM1E-8-155 interfaces with an LC-SC converter.

Similarly, after the second card set is replaced, perform the same update for the interfaces on the new card set. Otherwise, the upgrade is not graceful and becomes service affecting, until appropriate cables are installed.

•When MGX-8850-APS-CON is used, and one trunk-backcard is removed, screw the remaining backcard in completely to ensure that the contacts are complete.

•When MGX-8850-APS-CON is used, the Combo card and the PXM1E-4-155 card do not require a mini-backplane, but the PXM1E-8-155 does. Therefore, to support graceful upgrade to the PXM1E-8-155 card in the future, insert a mini-backplane with the PXM1E-4-155.

PXM1E Reserved VCIs

You cannot provision the following reserved VCIs:

•On a feeder trunk, VPI.VCI 3.8 is reserved for inband communication with the feeder shelf, and 3.31 is used for the feeder trunk Annex.G ILMI.

•VPI = 0 and VCI = 5 are used for SSCOP for UNI signaling ports.If the port is configured for non-signaling (univer = none), no VPI/VCI is reserved.

•VUNI uses configured VPI and VCI = 5 for SSCOP.

•EVUNI uses minimum VPI and VCI = 5 for SSCOP.

•NNI uses VPI = 0, VCI = 18 for PNNI RCC.

•VNNI uses configured VPI for the port and the VCI = 18 for PNNI RCC.

•EVNNI uses minimum VPI and the VCI = 18 for PNNI RCC.

•VPI = 0 and VCI = 16 are used for ILMI if ILMI is enabled. VUNI and VNNI uses configured VPI for the port and VCI = 16 for ILMI. Similarly, ILMI for EVNNI or EVUNI uses a minimum VPI and VCI = 16.

•If MPLS is configured, VCI = 33 in the similar fashion as above.

•If NCDP is configured, minimum VPI and VCI = 34 for NCDP clocking.

•VPI = 0 and VCI = 31 are used for online diagnostics.

PXM1E Point to Multipoint Support

Point-to-multipoint connections support new real-time and non-real-time applications, for example LAN emulation, distance-learning, live broadcasts, financial data delivery (stock market feeds), white board collaboration, video conferencing, data and file replication, and video on demand.

Multipoint enhances network efficiency because multiple streams of data can be replaced by a single transmission up to the multicast distribution point, typically a MGX with PXM45. Point-to-multipoint differs from broadcast because it replicates packets only to specific destination endpoints in the multicast distribution tree.

The MGX 8830 (PXM1E) and MGX 8850 (PXM1E) can be used in conjunction with an MGX (PXM45) in a network to support point-to-multipoint connections. The PXM45 hardware performs cell replication to multiple destination endpoints. The MGX with PXM1E functions as the originating node or as an intermediate node of a point-to-multipoint connection. If necessary, MGX with PXM1E can perform limited branching or cell replication to support multiple parties, or leaves, of a point-to-multipoint connection.

Enabling cell replication or branching of more than two leaves per root in the PXM1E node is not recommended for mission-critical point-to-multiple connections because of potential ATM cell drops. Cisco plans to enhance the PXM1E embedded hardware in the future to support cell replication for higher root/leaves ratio with minimal cell drops.

PXM1E Parity Errors

The PXM1E handles parity errors as follows:

•If the PXM1E card has a CBC CBH RAM parity error and all connections do not have traffic, then the PXM1E card fails to detect this parity error and does not switch over to the standby card. Also, all service module cards reset.

•The PXM1E standby card comes up even after a QE TS RAM parity error.

PXM1E Policing Accuracy

The PXM1E card has a policing accuracy limitation. The policing rate is defined as 50000000/PCR, so if the PCR is comparable to the OC-12 line rate (1412830), the policing rate parameter is a relative small number (50000000/1412830 = ~35.38996).

Because the PXM1E performs integer division, the decimal results are truncated and the policing parameter is not calculated accurately. Moreover, the policing rate parameter is stored as an exponent (5-bits) and mantissa (9-bits), which cannot represent a small number accurately. Therefore, a 100% accurate policing parameter cannot be configured for large PCR values.

To ensure that you get the rate that you have specified, the software configures policing at the next larger rate that the hardware supports. For example, if you program a connection with PCR = 1400000, the software programs the actual policing rate to be 1428571. For a worse case scenario, if you configure a VBR2 connection with a PCR of 1400010 and the ingress user traffic is 1428570, there is no policing because the ATM policing device would police at rate 1428571 only.

PXM45 and PXM1E System Limitations

The following limitations apply to PXM45 and PXM1E systems:

•Because of granularity limitations in the AXSM-E hardware, cell traffic does not reach the configured PCR rate when WFQ is enabled. For connections that have WFQ enabled, configure a PCR of 101% of the actual required rate. ABR has the same Qbin priority as UBR in the SCT tables. In this case ABR and UBR share excess bandwidth if WFQ is enabled.

•The percentage trunk utilization with overbooking is calculated using the following formula:

–(overbooked MaxCR - overbooked ACR) / overbooked MaxCR. This occurs when inter-operating with SES from Release 3.0.x and higher.

–ACR = MaxCR - (trunk utilization / overbooking factor).

–overbooked ACR = ACR / overbooking factor.

–overbooked MaxCR = MaxCR / overbooking factor.

•The overbooked ACR is calculated differently for MGX and SES.

–On MGX, the bandwidth for all current connections on the port are considered overbooked when calculating the trunk utilization.

–On the SES, the bandwidth for all current connections on the port are not considered overbooked when calculating the trunk utilization.

Therefore, the trunk utilization calculation is lower on the MGX than on the SES when there are existing connections on the port with an overbooking factor configured. This in turn yields a lower percentage trunk utilization on the MGX compared to the SES.

•The PXM45/A card is not supported in Release 5.0.00 and higher.

•Disable complex node for physical nodes (the lowest level node) to decreases memory usage without decreasing functionality. Complex node should only be turned on for logical nodes.

•Simple Network Timing Protocol CWM MIB is not supported.

Maximum Threshold Accuracy

The PXM45 and PXM1E have a limitation with the accuracy of the maximum threshold. 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). Therefore, you cannot calculate an exact 100% correct discard rate.

To ensure that you get the rate that you have specified, the software configures Qbin depth at the next larger rate that the hardware supports. As a result, Int. Cell Gap (ICG) and Relative Service Delay (RSD) are truncated.

Clearing the Configuration on Redundant PXM45 and PXM1E Cards

These notes apply to redundant cards.

•Because of checks to prevent an inserted card from affecting the system, an additional step might be required when inserting two non native 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 a clrallcnf, explicitly clean up stale SCT files (see anomaly CSCdw80282).

SPVC Interoperability Limitations

SPVCs have the following interoperability limitations:

•NNI SPVC Addendum Version 1.0 is not supported.

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

•Terminating single-ended SPVCs on MGX switch with legacy service modules is not supported.

•Origination of single-ended SPVCs, with slavepers flag, from legacy service modules (FRSM, CESM and RPM) is not supported.

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

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

•The tstdelay command is not available at the slave end of a single-ended SPVC for MGX 8850. For SES-PNNI, the command is available from the PXM even for the slave endpoint.

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

•If single-ended SPVCs originate from MGX switches, they can only be configured from the CLI and not from CWM.

•Single-end provisioning is not supported for DAX connections as 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 remains, the connection might get established as a single-ended SPVC connection. In this case, CWM shows the connection as Incomplete.

•Override of SVC connections on a VPI because of an incoming SPVP request for that VPI is not supported. Only the following override options are supported:

–spvcoverridesvc

–spvcoverridesvp

–spvpoverridesvp

Service Card Limitations

This section describes service card limitations.

AXSM-16-155-XG with MCC Back Card Limitations

You might experience the following scenario when card to card APS is configured on one card but not the other:

The Protection Line Status in dspapslns or dspapsln shows OK if the other side has added the card redundancy and activated the line but not the APS. If the back cards are SFP back cards, the Protection Line Status is in SF in the same setup.

From CLI screen on the side of APS added, the only way to find out if the remote APS has been added is through the Receive chanfield and modefield in dspapsln. The following display shows the APS status during configuration:

For GR253:

Receive k2 chanfield - Null Channel

Receive k2 modefield - Undefined

After adding remote APS (with MCC):

Receive k2 chanfield - Null Channel

Receive k2 modefield - UNI1+1 or Bi depending on mode

For ITU (or AnnexA)

Receive k2 chanfield - Null Channel

Receive k2 modefield - Undefined

After adding remote APS:

Receive k2 chanfield - Null Channel

Receive k2 modefield - Undefined

For AnnexB:

Receive k2 chanfield - Null Channel

Receive k2 modefield - Undefined

After adding remote APS:

Receive k2 chanfield - Working Section 1 or 2

Receive k2 modefield - Undefined

AXSM-32-T1E1-E and PXM1E-16-T1E1 Card Limitations

The following notes apply to the AXSM-32-T1E1-E and PXM1E-16-T1E1 cards:

•IMA version fall back is part of IMA group operation. If a group is configured with version 1.1 and it is connected to a far end group which is configured with version 1.0, this group falls back to version 1.0.

•The IMA link Loss of IMA Frame (LIF) and Link Out of Delay Synchronization (LODS) defect integration times are configurable.

•ATM layer configuration for line and IMA ports takes an additional parameter, AIS enable. It is enabled by default.

•In T1 mode, payload scrambling is disabled by default and in E1 mode it is enabled by default on all lines and IMA groups.

•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 E1. They are not supported for the T1 interface.

•HMM support is not available for the IMA and the Framer devices. When a switchover occurs, it can take up to 3.5 seconds for the IMA groups to recover. Data is lost until the groups recover.

•IMA Auto-restart (persistent RX IMA ID) feature is supported.

•IMA groups cannot have links from upper and lower bays together.

•ITC clocking mode on IMA is not supported.

•One-way transmission delay of more than 500 ms on the T1/E1 IMA links is not supported.

•There is 5 ms fluctuation on IMA delay tolerance.

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

–Any changes to this IMA group configuration are temporarily 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 when the links are added/deleted from the IMA groups.

•The thresholds for the connections added when there are N links in the group can differ from connections added when there are (N+1) links in the IMA group.

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

•The port number in the pnport (shelf.slot:subslot.port:subport) could be a random number. Do not interpret this number as line or IMA group number. Refer to anomaly CSCdy08500.

•PNNI requires SCR = 453 cells per second and PCR = 969 cells per second for the control connection.

•SSCOP requires of SCR = 126 cells per second and PCR = 2000 cells per second.

AXSM-E Card OAM Limitations

The following notes apply to AXSM-E OAM cells:

•Any connection can receive E2E/OAM loopback cells up to the line rate, as long as the policing policy permits it.

•The AXSM-E card can receive up to 1,500 segment OAM loopback cells per second for all connections operating in the normal mode (not loopback), assuming an even flow rate. Any excessive segment OAM loopback cells are dropped.

For example, if only one connection exists, that connection can receive 1,500 segment OAM loopback cells per second. If 2,000 connections exist on an AXSM-E card, and each connection passes one segment OAM loopback cell per second, then only 1,500 of the connections can receive loopback cells at any given second. The additional 500 loop back cells are not received for that second.

General AXSM Card Limitations

If ER stamping is used, the rate interval does not provide sufficient accuracy to be completely effective. As a result, when an AXSM card has a PNNI link that is congested with mixed CBR/ABR traffic, cells are dropped. This condition only occurs when ER stamping is enabled and CI is disabled on an AXSM PNNI link where CBR/ABR traffic causes congestion on the link.

Use the CI/EFCI mechanism for rate feedback rather than the ER stamping mechanism, especially if CBR/ABR traffic is expected.

AXSM-XG Signal Level Limitation

The IR/LR/XLR SFP modules need a 10 db attenuator when connected with short cables. Otherwise, the signal overloads the receiver.

ATM Multicast Limitation

Configure an MGX 8950 with ATM multicast as follows:

•MGX 8950 system loaded with AXSM/Bs without AXSM-XG cards in the system

•MGX 8950 system loaded with all AXSM-XG based cards without AXSM/Bs in the system.

An MGX 8950 system with a mix of AXSM-XG and AXSM/B cards is not recommended for the ATM multicast application because of limitations in the backplane serial buses. The workaround for MGX 8950 systems that must have a mix of AXSM-XG and AXSM/B cards is to configure the PNNI node as branching restricted.

cnfpnni -node 1 -branchingRestricted on.

Priority Bumping Limitation

When you enable priority bumping on the node, you cannot change the booking factor for AXSM signaling ports. You can still change the booking factor for non-signaling ports.

AXSM Card APS Limitations

Thee APS feature has the following limitations:

•For AXSM APS, the backcard of the active card must be present for correct APS operation.

•AXSM front cards need the corresponding backcard for correct APS operation. In other words, the AXSM cards do not support cross backcard removal—the upper backcard of one AXSM and lower backcard of another AXSM.

•If you remove the upper backcard of the active front AXSM, it triggers an active card switch. At this point the APS is still operational. However, if the lower backcard of the current active AXSM is removed, it will not trigger switching because the standby card is missing the backcard.

•Port LED lights on AXSM-E, AXSM-XG and PXM1E front cards indicate the receive status of physical line connected to it only when the card is in the active state. For a standby AXSM-E, AXSM-XG, and PXM1E card, the LEDs always remains green when the lines are in LOS irrespective of which lines are active.

MPSM Card Limitations

The MPSM cards have the following limitations:

•The MPSM-T3E3-155 card does not support the LMI Autosense feature.

•The MPSM-8T1-FRM and MPSM-8E1-FRM cards do not support the LMI Autosense feature.

•If a combination of RPM-PR and MPSM-T3E3-155 cards are being installed in slots served by the same cell bus, then enable Option 10 of cnfndparms (auto clock rate setting) before installing the MPSM-T3E3-155 and RPM-PR cards. This note applies when two RPM-PR cards or two MPSM-T3E3-155 cards (or one RPM-PR and one MPSM-T3E3-155 card) are inserted into slots under the same cell bus master, for example, slots 5 and 6 or 3 and 4.

•The MPSM cards are cell bus based cards, and they have limitations that suggest only a few of these cards could be used in a chassis when running at full port rate.

In reality, the full port rate available is rarely used. Statistical multiplexing of traffic across many ports can allow overbooking of the cell bus capacity just as it allows overbooking of trunk capacity. Estimates on how much overbooking is practical without dropping cells relies on the network's characteristics, such as the mix of service types, port speeds, and offered traffic loads as a percentage of port speed or as generated cell rates. Work with your Cisco Customer Engineering representative to help you characterize the quantity of MSPM cards suitable for your network.

•If you order MPSM cards with systems, the MPSM license(s) will be shipped on the PXM card. For more information, refer to MPSM Licensing section of the Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830 Configuration Guide, Release 5.1.

MPSM-16-T1E1 Card PPP Limitation

On the RPM-XF, Rated Priority Queue is not supported; SAR based QoS is enabled instead. The traffic on priority queue can exceed the limit even if the class-based weighted fair (CBWF) queues are relatively free. RPM-XF supports absolute priority only, where the upper limit on the traffic is layered using the policing command.

CBSM Card Limitations

Cell Bus Service Modules (CBSM), formerly known as narrowband service modules, have the following limitations:

•When switchredcd is entered at the same time as a PXM switchover occurs, either through the switchcc/resetcd command at the PXM or because of a failure, the switchover can fail.

Conditions: switchredcd is entered at the PXM command line to perform CBSM Switchover, but the PXM switches over (manual or automatic) before the service module switchover is complete.

Symptom: Service module did not switchover after switchredcd.

If the PXM switches over before the CBSM switchover completes, the following can occur:

–The switchover might not be complete and the standby card is in an indeterminate state. The dspcd command from PXM still shows it as 'standby' and later switchover (because of active service module removal or reset) fails, causing loss of traffic. The switchredcd command also fails.

–The switchredcd from PXM again causes the failure because the standby service module is not able to allocate memory.

Workaround: Reset the standby service module card.

•Each CBSM has the following maximum number of connections:

–FRSM-8 = 1,000

–FRSM-2CT3 = 4,000

–FRSM-2T3 = 2,000

–FRSM-2E3 = 2,000

–CESM-8 = 248

IGX Feeder Limitation

After adding an IGX as a feeder to a SES/BPX or MGX node, the IGX has a default node number that might not be unique within the network. If the number is not unique, modified it to a unique node number by entering rnmnd <x>, where x is unique with respect to all other AutoRoute nodes. To find the other node numbers, enter dspnds +n. Failing to assign a unique number could cause the CWM Databroker to incorrectly form hybrid connection database. The CWM GUI might show the connection as incomplete.

Clock Source Limitations

Service modules have the following clock source limitations:

•The AUSM card supports one clock source only. Attempts to configure the secondary clock fail silently.

•The FRSM card does not support clock source configuration. If a clock source is configured on FRSM, it is not be reflected in the database.

•When resetcd is invoked, the primary and secondary (if configured) clock sources are recommitted. Recommitted means that the primary and secondary get requalified. The node temporarily uses the internal oscillator until the clock is requalified, and then locks onto the primary clock source again.

Clearing Card Configuration Notes

The clear service module configuration feature has the following behavior:

•Cisco does not recommend executing clrsmcnf on more than one card at a time

•If a controller card switchover occurs before the clear service module configuration operation is complete, the clrsmcnf command must be re-entered to ensure that the configuration is completely cleared and to avoid incomplete cleanup.

•The clrsmcnf command might result in discrepancy in the PNNI configuration. For example, some connections might be in the mis-match state.

•If the clrsmcnf command is entered with the <all> option to clear the software version for the slot as well, then cell bus service modules go into the boot/empty state and broadband service modules (for example, AXSM or MPSM-155-T3E3) go into the fail/active state.

•After entering the clrsmcnf command, the card in the specified slot is not usable until the operation has successfully completed.

PNNI Limitations

This section describes limitations to PNNI links and routing.

Logical Link Limits

The numbers of logical links in the higher levels of the PNNI hierarchy is limited to 30 per level when the complex node configuration is enabled. The limit is essential to reduce the processing time involved in finding the bypasses between the logical links. Whenever a significant change occurs in bandwidth in one of the links within the peer group, the bypass calculation is triggered and the bypasses are usually found from one logical link to another.

If there are n logical links, the calculation involves the finding n*n bypasses. If the number of logical links n is large, calculating the bypasses requires significant processing resources. The number of logical links can be controlled by configuring the appropriate number of aggregation tokens for the outside links for that peer group.

Preferred Route Limitations

Preferred routes have the following limitations:

•Preferred routes are not supported for connections with endpoints on the RPM-PR.

•Upgrading a preferred routing from any Release 3.0.x is non-graceful. During the upgrade, the preferred route identifier information for each connection is lost, and the preferred route identifier must be reprovisioned on the service module cards.

Also, the preferred route table at the PXM controller is lost. Connections that have already been routed with preferred routing remain, and no alarms for these connections occur. If a node in the PNNI network is removed by physical decommissioning and if any nodes in the network had preferred routes that contained the removed node as one of the hops, you must manually delete and modify the preferred route(s).

•When a connection is routed on a route other than its preferred route and if the preferred route becomes available, the connection is not automatically routed back to its preferred route. You must deroute and reroute using configuration commands (optrte, rrtcon, dncon/upcon, and so on). QoS precedence over the preferred route does not apply to multi-peer group networks (CSCdz40310).

•A preferred route configured with a higher node ID cannot be blocked (CSCdz41145, CSCdz49001). Because of differences in physical port numbering, non-MGX nodes can only be the terminating nodes in a preferred route.

•Preferred route status is supported in Release 5.0.00 and up. After an upgrade, manually reconfigure using commands like cnfcon. This step is only needed only once after the upgrade, and does not need to be repeated on subsequent upgrades.

Priority Route Limitations

Priority routing has the following limitations:

•Prioritized reroute of SPVCs is not guaranteed if the SPVCs originate on a signaling port. SPVCs might get routed out of order. In-order routing of SPVCs is guaranteed on non-signaling ports only.

•The RPM does not support configuration of routing priority. The PXM assigns a priority of 8 to all RPM-mastered SPVCs.

•The addcon command on SES does not support routing priority; all added SPVCs are assigned a routing priority of 8. Use the cnfcon command to change the routing priority of the SPVCs.

•Changing the routing priority for DAX connections does not change the priority of the associated SVCs. The SPVCs are not derouted and rerouted if only the endpoint parameters are changed, and routing priority is an end-point parameter. Also, because DAX connections are never derouted even when the UNI port goes down and the rrtcon command does not support DAX connections, the routing priority change never gets reflected. The only way to reflect this change is to enter a dncon and then upcon. Because DAX connections are never derouted, the effect of this limitation is void.

•Priority routing operates in a best effort manner for 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, releases can be transmitted out-of-order. This is because releases of other calls must not be held up if you are not able to send releases on one of the congested interfaces. The calls that were not released could be higher priority calls.

•Lower priority SPVCs can be routed ahead of higher priority SPVCs. This can occur after several failed attempts to route higher priority SPVCs. To prevent starvation of lower priority SPVCs after these failures, software starts to route lower priority SPVCs and postpones higher priority SPVCs routing.

Persistent Topology Limitations

The persistent topology feature has the following limitations:

•In a mixed network of pre-Release 4.0.00 and 4.0.00 or later nodes, only the node name and the node ID are shown for a pre-Release 4.0.00 node in the Topo DB. This is because the feature is not present in pre-Release 4.0.00 nodes.

•If a peer group is made up of physical nodes with pre-Release 4.0.00 logical nodes, the information for the logical node is stored in the Topo DB. This is because there is no way to distinguish between physical nodes and pre-Release 4.0.00 logical nodes. Logical nodes with Release 4.0.00 or later software release are not stored in the Topo DB.

•To delete a node information entry from the Topo DB, first remove the node from the network, either by disconnecting the cables or by downing all the links between that node and the network. Wait for an hour. Then, delete that node from the Topo DB. This is done because, even if a node is removed from the Topo DB of all nodes in the peer group, its PTSEs are still 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 Topo DB within that hour's time, and the node does switchcc/reboot, then it's possible that the node info for that deleted node will be added back into the Topo DB.

•When the node ID of a node is changed, the old node ID is added back into the Topo DB as a new node entry. In addition, the old node ID still is stored in the Topo DB of all the other nodes in the peer group. To delete this entry, wait for an hour so that the PTSEs with the old node ID is flushed from the DB of all the nodes in the peer group. Then, delete the information of the old node ID from the Topo DB.

•It is possible that the gateway nodes are not in sync 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 PG, and another gateway node is configured, then the info 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 deleting a node from the peer group, the node info must be deleted from all the nodes in that peer group, even the non-gateway-node nodes. Otherwise, the node info 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.

Fault Isolation and Trace Limitations

This section describes fault isolation and trace limitations.

Serial Bus Path Fault Isolation Limitation

The Serial Bus Path Fault Isolation feature isolates errors on local cards only. However, when a common error occurs on the switching fabric card, this feature does not resolve the error. As a result, a problem on the PXM card or the XM-60 is reported by all cards that detect the symptoms of this problem.

Cell Bus Path Fault Isolation and Recovery Limitations

Cell bus path fault isolation has the following limitations:

•The isolation procedures can isolate the cell bus path in the serial bus service modules (for example, AXSM, AXSM/B, AXSM-E,) and all communication with the standby controller card and the cell bus service modules (for example, FRSM, CESM). These procedures cannot isolate cell bus path failures involving the ATMizer SAR, which is used for all inter-card communication except polling, between the active controller card and the serial bus based service modules.

•The isolation procedures can isolate the cell bus path failures to the active controller card only. This isolates the active controller card faults for the inter-card communication over the cell bus from the active controller card to the service modules and the standby controller card. 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.

•At least two cards (two service modules or one service module and one standby PXM) must exist to isolate cell bus path failures to the active controller card.

•Only failures that are detected by periodic polling trigger the isolation procedures. Failures reported from other sources in the system about a service module or the standby controller card, due to the cell bus path failures, do not initiate the isolation procedures. Such failures reset the card for 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.

•No separate trap or alarm is generated for the active controller card cell bus path when the fault is isolated to the active controller card. Use the event logs to investigate events triggered by the card reset and/or switchover traps.

•If controller card redundancy is unavailable, isolating the cell bus path failure to the active controller card results in outage. The active controller card is reset.

Path and Connection Trace Notes

The path and connection trace features have the following limitations:

•Path trace is not supported on the control port.

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

•Path and connection trace after Release 3.0.00 is not compatible with the path and connection trace available with previous releases.

•Path and connection trace supports point to point connections.

•Path and connection trace supports MPG (multi-peer group) and SPG (single-peer group).

CLI Access Level Notes

Configuration of CLI access levels has the following limitations:

•Not all CLI command access levels can be changed and a command cannot be changed to CISCO_GP group access level.

•Only the switch software can generate the access level 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 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.

•Command names are verified, but an invalid command name might be parsed and be added to the binary file. However, this invalid name is ignored later.

•If replication to standby failed, the installation process failed.

The cnfcli accesslevel default command restores all command access levels to default for the service module on which the command is executed. This command does not remove the binary file, so this change is not persistent. If the command 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.

Disk Space Maintenance Notes

The firmware does not audit the disk space usage and remove unused files, so you must manually manage the disk space in C: and E: drives.

Manually delete 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. This avoids a shortage of disk space for storing event logs.

Too remove files from the active controller card:

---

Step 1 Change to the directory that needs grooming.

cc <directory_name> 

Step 2 List the directory to identify old files that can be removed and available disk space.

ll 

Step 3 Remove any old files (you may also use wild cards in the filename).

rm <complete_filename> 

Step 4 List the directory to see if the file has been removed and disk space is available.

ll

Non-native Controller Front Card and PXM-HD Card Notes

The following notes pertain to non-native front card controllers and the PXM-HD card:

•When the front controller cards or the PXM-HD back cards are swapped within the same system, the system performs a non-native card check. As a result, the controller card that attempts to come up as Active/Active might get reset twice.

•When a non-native PXM1E front card or a PXM-HD card is inserted into the standby controller slot, after the standby controller front card becomes Active/Standby, the active controller front card copies its hard disk content over to the standby controller card. The active controller front card does not automatically remove hard disk content from the active or standby controller card.

•The system keeps only the two most recent copies of the saved system configuration in the C:/CNF directory. You can use FTP to transfer all the saved configuration files in C:/CNF to a local server for future reference. All files under C:/CNF are not replicated to the standby controller card under any circumstances.

Other Limitations and Restrictions

Other limitations and restrictions are as follows:

•When configuring virtual interfaces (for example, VUNI, VNNI, EVUNI, EVNNI), the physical interface must be of all one ATM header type, either UNI or NNI. 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.

•If command clrchancnt is executed while a dspchancnt command is currently active, the data displayed is incorrect. Restarting the dspchancnt after the previous one has completed displays correct data.

•The clrsmcnf command does not work for redundant service modules.

•The clrsmcnf does not work if an upgrade is in progress.

•If RPM-PR or RPM-XF is configured as a Label Switch Controller (LSC), execution of clrsmcnf command on those LSC slots is rejected.

•Configuration information is not synchronized between PXMs during upgrades. If any changes are made to the configuration during upgrades, the standby PXM must be rebooted. The standby PXM must be rebooted when it is in a stable state.

•The maximum number of connections supported in Release 3.0.00 or later with PXM45/B is 250,000 connections.

•NCDP is not supported on BPX.

•When you clear the channel counters while you are monitoring the channel counters on the AXSM-XG, the counters return invalid values on the dspchancnt display (see CSCdz33652).

Upgrading AXSM-XG Cards

The following notes apply to AXSM-XG card upgrades:

•When installing AXMS-XG cards into a node that has a release earlier than Release 4.0.15, all of the other cards in the node must be upgraded first to Release 5.0.

•When configuring virtual interfaces (for example, VUNI, VNNI, EVUNI, or EVNNI), the physical interface must be of all one ATM header type, either UNI or NNI. The signaling that is applied to a virtual port is independent of the actual virtual port ATM header. The only limit is that the VPI value must be within the UNI ATM header limitations.

For information about graceful upgrade of AXSM-XG cards, see the "Upgrading an AXSM/A, AXSM/B, or AXSM-E to an AXSM-XG" section.

Upgrading the VISM-PR Image

If you are upgrading the VISM-PR image to Release 3.2.1x or later and the PXM1E or PXM45 image from Release 4.x or earlier to Release 5.x, first upgrade the VISM-PR cards. Then, upgrade the PXM1E or PXM45 cards in the same node.

Do not configure the new VISM features until you have fully upgraded the network. After you upgrade your network to PXM1E or PXM45 Release 5.x or later and VISM-PR to Release 3.2.1x or later, apply the standard upgrade process.

CSCeh18475	Headline: Connection down and rerouted after APS Pline removed (AnnexB Only) Symptom: Port/connections fail after glitch in the protection line when working line is in alarm. Condition: Working line of the APS pair was in SF state and secondary->primary switchover occurs. Workaround: None Hardware: AXSM-XG
CSCeh66111	Headline: Alarm in B/W MPSM-MF line and FRSM CAS line takes more than 2 hours to clear. Symptom: Framing errors on MPSM E1 lines. Conditions: Occurs with MPSM line in MF or MF-CRC mode, when connected to FRSM-8 in CCS/CCS-CRC mode. Workaround: Configure a different framing mode for the line. Hardware: MPSM-16-T1E1
CSCeh20665	Headline: AXSM-XG NVRAM gets corrupted Symptom: AXSM-XG cards show up as having a corrupted NVRAM. Condition: If an AXSM-XG card is moved to a different slot or chassis type (for example 8850 to 8950) while the chassis/PXM is powered off there is a remote chance that the NVRAM will be corrupted and the card will fail to boot on the next card initialization. Workaround: Ensure that the chassis and PXMs are powered up before installing the AXSM-XG cards in the new slot. Hardware: AXSM-XG
CSCeh72899	Headline: Wrong OIDs populated for Xmt CLP0 and CLP1 cells Symptom: The wrong OIDs were populated for Egress CLP0 and CLP1 cells. Condition: Performing an snmpget/walk on: caclOutXmtCLP0Cells 1.3.6.1.4.1.9.9.133.1.2.1.1.18 caclOutXmtCLP1Cells 1.3.6.1.4.1.9.9.133.1.2.1.1.19 and caclIntervalOutXmtCLP0Cells and caclIntervalOutXmtCLP1Cells would return zero, while the same values were populated in the corresponding Rcv OIDs. For example, caclOutRcvCLP0Cells would be populated instead of caclOutRcvCLP0Cells and so on. Workaround: None Hardware: SNMP-agent
CSCeh93023	Headline: Standby card reset for RAM sync error during line/path decommission Symptom: On an MPSM-T3E3-155 card configured with redundancy, executing a delppplink followed immediately by a dnpath results in a RamSync error on the standby card and the card resets. This problem is repeatable only from the test script, not from the CLI. Condition: RamSync Error which causes standby card reset. Verify by entering dsperrhist <slot>. Workaround: Because this occurs only with delppplink followed immediately by dnpath, you can work around the problem by adding a 1 second delay between the two commands. Hardware: MPSM-T3E3-155-PPP
CSCeh94891	Headline: Standby PXM45 in init state Symptom: Standby PXM45 is stuck in init state. Condition: PXM45 on MGX running 3.0 bootcode. Workaround: Use cnftopogw on to turn on the gateway node, then reboot PXM45. This will allow the standby to be updated correctly. Hardware: PXM45/C
CSCeh95285	Headline: TRL in IMA lines is not moving after swithcc in node Symptom: An IMA group between an PXM1e-T1e1 and AUSM did not recover after switchcc. Condition: TRL for AUSM was stuck at a line which was in critical alarm and the IMA group never came back. Workaround: Deleting the line that has critical alarm from the IMA group. Hardware: PXM1E-IMA
CSCei13891	Headline: Policing on VBR.2 connections allowing more CLP1 cells Symptom: More CLP1 cells being allowed than should be allowed. This could potentially result in network congestion. Condition: VBR.2 Connections for both rt and nrt types. Workaround: None Hardware: AXSM
CSCei17194	Headline: dspcon in conditioned alarm. no log detail on PXM45/B controller. Symptom: PVC connection fails and raises a conditioned alarm, which does not clear. Condition: Occurs when running a script that repeatedly performs delcon/addcon. Workaround: Perform delcon/addcon again. Hardware: MPSM-16-T1E1-PPP
CSCei19268	Headline: Auto-restart sync state stuck in loopbacksync even when tx/rx id are different. Symptom: The sync state is loopbacksync instead of tempSync when the IMA IDs are different. Condition: Occurs when IMA ID's are different between groups on AXSME and MPSM-16-T1E1 cards. Workaround: None Hardware: MPSM-16-T1E1
CSCei35633	Headline: Paths fail after switchredcd is issued on MPSM-155. Symptom: E1 paths down. Condition: After two or three sequential switchredcd commands. Workaround: None Hardware: MPSM-155 OAM
CSCei47617	Headline: Line error increasing on SRME/B T3 while in loop Symptom: SRME/B card with T3 interfaces constantly registering line errors. Condition: Loopback Workaround: None Hardware: SRM/SRME
CSCei59862	Headline: ILMI goes down when traffic is stopped Symptom: ILMI protocol goes down on AXSM-XG-OC48 during OC48+OC3 traffic load. Condition: The problem occurs under the following conditions: •Trunk ports are configured for 5651320 cps •ILMI enabled •OC48 + OC3 traffic pumped through this trunk •Stop the traffic Workaround: Set the port rate to 5645000 to resolve the problem. Hardware: AXSM-XG-OC48
CSCei66081	Headline: Invalid message code for conntrace on SES Symptom: conntrace from a SES might timeout if a PNNI node of another vendor is on the path. dspconntracebuffer 3.1 100 125 Last update time: Jul 22 2005 6:48:13 Result: FAILURE Reason: Time Out Physical PortId: 3.1 VPI:100 VCI:125 Condition: SES is on the path of multi-vendor PNNI network. Workaround: Use dsppncon for the connection segment within the SES network. Hardware: SES
CSCei71643	Headline: Switchover of MPSM-PPP T3 cards exceeds 8 second requirement Symptom: Variable time outage on traffic loss with different rate of traffic when executing switchover on MPSM-T3 redundancy group. Condition: Traffic outage increases as the traffic increases Workaround: None Hardware: MPSM-T3E3-155 OC3-PPP
CSCei75053	Headline: pnniport interface stuck in building VC at AXSM-XG card. Symptom: dsppnports shows a UNI port stuck in "building vc" state. Condition: All lcns (126976) on the AXSM-XG card must be reserved/committed. Then the following sequence of actions may cause the problem intermittently: 1. uppnport and dnpnport the UNI port 2. remove and re-add a physical loopback cable for the port 3. addlnloop and dellnloop for the port Workaround: After the problem occurs, perform dnport/upport to recover. Because the conditions that lead to the problem are already service affecting, this workaround is reasonable. Its only cost is the delay when running dnport/upport. Hardware: AXSM-XG
CSCei82475	Headline: CLP 0 discards on ABR connections when intvsvd is enabled. Symptom: CLP 0 congestion discards occur on egress of ABR connection on all AXSM-XG cards.

The following upgrade procedure goes into Appendix A. For information about updated commands for the graceful update feature, see the Cisco MGX 8850 (PXM45/PXM1E), Cisco MGX 8950, and Cisco MGX 8830 Command Reference, Release 5.1.

Upgrading an AXSM/A, AXSM/B, or AXSM-E to an AXSM-XG

The AXSM-16-155-XG and AXSM-8-622-XG cards have a higher port density than the equivalent AXSM-E cards, and the AXSM-16-155-XG and AXSM-8-622-XG have better traffic management support than their AXSM/B counterparts. Using the procedures in this section, you can gracefully upgrade AXSM, AXSM/B and AXSM-E cards to AXSM-XG cards.

Graceful upgrades simplify the process of migrating to the newer AXSM-XG cards. During the upgrade, the MGX control processor transfers the configuration/connection database from the previously installed AXSM card to the new AXSM-XG, which preserves all connection configurations. The upgrade process might cause an outage of up to four minutes.

Supported Configurations

Graceful hardware upgrades from AXSM-A/B/E OC-3/OC-12 release 4.0.17 or greater to AXSM-XG OC-3/OC-12 in standalone or redundancy with Y-cable configurations are supported.

---

Note Graceful migration applies to AXSM A/B/E OC3 and OC12 cards only.

---

Limitations

The following limitations apply to graceful upgrades:

•AXSM-A/B do not support Y-cable in MMF configuration

•AXSM-XG-622 lines cannot be set to both SONET and SDH on the same bay. If the card to upgrade has both SONET and SDH lines on the same backcard, separate the lines into different bays before starting the migration.

•AXSM OC48 cards cannot be gracefully upgraded to AXSM-XG OC48 cards in the MGX 8950 chassis because the back cards are physically incompatible. However, non-graceful upgrade is supported.

•Upgrade of AXSM-A/B/E with SMB-4-155 to AXSM-XG with an electrical backcard (MCC-8-155) is not supported because of hardware limitations of the MCC-8-155 backcard.

•No more than 6 SCTs can be loaded onto the AXSM-XG at one time.

Preparing to Upgrade

Before performing the upgrade procedures, perform the following tasks:

•Upgrade all custom SCT files (See Converting Custom SCTs).

•Upgrade all other cards to version 5.2. This is very important, because failure to upgrade will cause connections on the upgraded card to other AXSM cards to change to the mismatch state.

•Verify that the AXSM to upgrade has less than 126,976 connections, which is the maximum number of AXSM-XG connections.

•Verify that the system is in good working order. This includes checking for alarms and verifying redundancy operation. Resolve any existing problems before starting the upgrade.

•Do not attempt to upgrade an electrical backcard with APS.

Converting Custom SCTs

The AXSM-A/B/E SCT files are not compatible with the AXSM-XG SCT files. The upgrade procedure automatically updates the default SCT files to the new format. However, customers that use custom SCTs must convert them to the AXSM-XG format before performing the upgrade. The following tables show the AXSM SCT mapping for Cisco-provided SCTs.

Table 23 AXSM-A/B to AXSM-XG SCT Mapping

AXSME_SCT.PORT.6.V1	AXSMXG_SCT.PORT.400.V1 (OC3) / AXSMXG_SCT.PORT.300.V1 (OC12)

To convert custom AXSM-A/B/E SCTs to AXSM-XG SCTs:

---

Step 1 Map the existing AXSM-A/B/E SCT to the new AXSM-XG SCT using Table 23 or Table 24.

For example, if the existing SCT was derived from AXSM_SCT.PORT.2.V1 (which has policing enabled for PNNI), the new SCT must be derived from AXSMXG_SCT.PORT.410.V1(which is specific for the OC3 card and has policing enabled for PNNI).

Step 2 Using a tool such as CWM, port the custom settings from the existing AXSM-A/B/E SCT to the new AXSM-XG SCT.

Step 3 Save the new AXSM-XG SCT using the same SCT ID that the existing SCT uses.

For example, if the existing SCT is named AXSM_SCT.PORT.40.V1, save the new SCT as AXSMXG_SCT.PORT.40.V1.

---

Graceful Upgrade Procedure

This section explains how to gracefully upgrade an AXSM-A/B/E card to an AXSM-XG card, and includes an example of upgrading an AXSM-A card to an AXSM-8-622-XG card.

---

Note Remember that if you experience problems with the upgrade, you can cancel it using the abortrev command.

---

The following display shows the example system, which includes two redundant AXSM/A cards to be upgraded, using the PXM dspcd command. Slot 10 is the active card, and slot 11 is the standby card. Inter-card APS is not configured, but lines 10.1.1 and 11.1.1 are connected using a SM fiber Y-cable.

To perform a graceful upgrade of a AXSM A/B/E to AXSM-XG card, follow these steps.

---

Step 1 Delete any inter-card APS configured on the AXSM A/B/E cards to be upgraded using the delapsln command.

---

Note Deleting APS may cause traffic outages.

---

Step 2 From the AXSM A/B/E card, enter the dspconinfo command and record the existing connection information. You will use this information later to verify successful migration of existing connections to the new AXSM-XG card.

Step 3 From the PXM issue the loadrev command, specifying the active slot of the redundancy pair, software version, and axsmxg keyword. The axsmxg keyword specifies that you are upgrading both hardware and software.

For example:

M8850_NY.7.PXM.a > loadrev 10 5.1(206.15)A axsmxg

one or more card(s) in the logical slot may be reset.

loadrev: Do you want to proceed (Yes/No)? y

Replace the card in slot 11 with AXSMXG now

M8850_NY.7.PXM.a > 

After entering the loadrev command, the card in slot 11 changes to the Mismatch state. For example:

---

Note The card may remain in Mismatch state if old hardware was still plugged in after a card reset with the new card type.

---

Step 5 Load the boot code on the standby AXSM-XG card using the PXM burnboot command, specifying the standby slot number and the boot code version. The standby AXSM-XG card is reset and upgraded to the specified boot software version. For example:

M8850_NY.7.PXM.a > burnboot 11 5.1(206.15)A

WARNING! burnboot is a destructive command if used improperly. 

Please DO NOT Abort or Reset the PXM/SM when the command is in progress, 

as this may corrupt the Boot image. 

The card in slot 11 will be reset.

burnboot: Do you want to proceed (Yes/No)? y

M8850_NY.7.PXM.a >

Step 6 If SCM is being used for statistics collection, disable statistics collection using the SCM GUI.

---

Note You cannot disable statistics collection using the MGX CLI; you must use the SCM GUI.

---

Step 7 From the PXM, enter the runrev command, specifying the active slot of a redundancy pair, the version number, and the axsmxg keyword.

---

Note In some cases, such as failed slot hardware, you must force the action using the -f option.

---

For example:

M8850_NY.7.PXM.a > runrev 10 5.1(206.15)A axsmxg

one or more card(s) in the logical slot may be reset.

runrev: Do you want to proceed (Yes/No)? y

Replace the card in slot 10 with AXSMXG now

M8850_NY.7.PXM.a > 

After issuing the runrev command, the PXM dspcds command shows card 10 in the Mismatch state.

Step 8 Insert the second AXSM-XG hardware, including front card, back cards, and cables.

Removing the existing hardware from the active slot invokes a redundancy switchover, and the standby AXSM-XG card transitions to the ACTIVE-U state.

The newly inserted AXSM-XG card becomes the standby card and transitions to the STANDBY-U state.

To perform a non-graceful upgrade of a AXSM A/B/E to AXSM-XG card, follow these steps.

---

Step 1 From the AXSM A/B/E card, enter the dspconinfo command and record the existing connection information. You will use this information later to verify successful migration of existing connections to the new AXSM-XG card.

Step 2 From the PXM issue the loadrev command, specifying the slot of the card to upgrade, software version, and axsmxg keyword. The axsmxg keyword specifies that you are upgrading both hardware and software.

M8850_NY.7.PXM.a > loadrev 12 5.1(206.20)A axsmxg

one or more card(s) in the logical slot may be reset.

loadrev: Do you want to proceed (Yes/No)? y

M8850_NY.7.PXM.a >  

After entering the loadrev command, the card in slot 12 changes to the Active-U state. For example:

Step 3 If SCM is being used for statistics collection, disable statistics collection using the SCM GUI.

---

Note You cannot disable statistics collection from the MGX CLI; you must use the SCM GUI.

---

Step 4 From the PXM card enter the runrev command, specifying the slot number, the version number, and the axsmxg keyword. For example:

M8850_NY.7.PXM.a > runrev 12 5.1(206.20)A axsmxg 

one or more card(s) in the logical slot may be reset.

runrev: Do you want to proceed (Yes/No)? y

Replace the card in slot 12 with AXSMXG now

After entering the runrev command, card 12 changes to the Mismatch state.

Note The card may remain in Mismatch state if old hardware was still plugged in after issue of card reset with the new card type.

---

Step 6 Load the boot code on the AXSM-XG card using the PXM burnboot command, specifying the slot number and the boot code version. The standby AXSM-XG card is reset and upgraded to the specified boot software version. For example:

M8850_NY.7.PXM.a > burnboot 12 5.1(206.20)A

WARNING! burnboot is a destructive command if used improperly. 

Please DO NOT Abort or Reset the PXM/SM when the command is in progress, 

as this may corrupt the Boot image. 

The card in slot 12 will be reset.

burnboot: Do you want to proceed (Yes/No)? y

Step 7 If SCM is being used for statistics collection, verify that the new card is ready for statistics collection and then enable statistics collection using the SCM GUI.

---

Note You cannot enable statistics collection using the MGX CLI.

---

Step 8 Verify that the upgrade was successful.

a. From the AXSM-XG card, enter the dspconinfo command and verify successful migration of all existing connections to the AXSM-XG. If necessary, wait for the migration to complete.

b. From the AXSM-XG card, enter the dspcd command and verify that all line, port, partition, and connections are correct, and that it displays the type of the card from which this AXSM-XG was upgraded.

---

Note You can revert to the previous hardware and software using the abortrev command.

---

Step 9 From the PXM, enter the commitrev command, specifying the slot number, version number, and axsmxg keyword.

M8850_NY.7.PXM.a > commitrev 12 5.1(206.20)A axsmxg

Cisco Product Security Overview

Cisco provides a free online Security Vulnerability Policy portal at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

From this site, you will find information about how to:

•Report security vulnerabilities in Cisco products.

•Obtain assistance with security incidents that involve Cisco products.

•Register to receive security information from Cisco.

A current list of security advisories, security notices, and security responses for Cisco products is available at this URL:

http://www.cisco.com/go/psirt

To see security advisories, security notices, and security responses as they are updated in real time, you can subscribe to the Product Security Incident Response Team Really Simple Syndication (PSIRT RSS) feed. Information about how to subscribe to the PSIRT RSS feed is found at this URL:

http://www.cisco.com/en/US/products/products_psirt_rss_feed.html

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you have identified a vulnerability in a Cisco product, contact PSIRT:

•For Emergencies only — security-alert@cisco.com

An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.

•For Nonemergencies — psirt@cisco.com

In an emergency, you can also reach PSIRT by telephone:

•1 877 228-7302

•1 408 525-6532

---

Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to encrypt any sensitive information that you send to Cisco. PSIRT can work with information that has been encrypted with PGP versions 2.x through 9.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

The link on this page has the current PGP key ID in use.

If you do not have or use PGP, contact PSIRT at the aforementioned e-mail addresses or phone numbers before sending any sensitive material to find other means of encrypting the data.

Obtaining Technical Assistance

Cisco Technical Support provides 24-hour-a-day award-winning technical assistance. The Cisco Technical Support & Documentation website on Cisco.com features extensive online support resources. In addition, if you have a valid Cisco service contract, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not have a valid Cisco service contract, contact your reseller.

Cisco Technical Support & Documentation Website

The Cisco Technical Support & Documentation website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, at this URL:

http://www.cisco.com/techsupport

Access to all tools on the Cisco Technical Support & Documentation website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:

http://tools.cisco.com/RPF/register/register.do

---

Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support & Documentation website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

For a complete list of Cisco TAC contacts, go to this URL:

http://www.cisco.com/techsupport/contacts

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of the network is impaired, while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
