2. In Release 9.2.31 the system parameter 2 (cnfsysparm2) is changed from "Fail Connections On Communication Break" to "Allow CPU Starvation of Fail Handler."
The old parameter has been removed as it violated the principle of the separating control and data plane. The new parameter allows a new feature to be turned off, which gives CPU to the Fail Handler at the expense of the Transaction Handler in case the Fail Handler does not get scheduled for a long time.
3. Do not mix MEE and MEF (or higher) in Y-red pairs for BXM 2-port group enhanced cards (OC-3 or OC-12 port). addyred will fail if both are in standby mode, or the primary card has been activated with MEF (or higher) and the secondary card has MEE.
4. For the BXM 2-port group, enhanced cards activated with MEF or higher, downrev to MEE will bring the cards into MISMATCH mode. This applies to both single cards and Y-red pairs.
5. Release 9.2.30 introduced four new commands in BPX:
addctrlr to add VSI capabilities to a trunk interface to which a Feeder of type AAL5 is attached. This command is basically run as the second step in adding a PNNI controller.
delctrlr to delete VSI capabilities from a trunk interface to which a Feeder of type AAL5 is attached. This command is basically run as the first step in deleting a PNNI controller.
cnfvsipart to configure VSI partition characteristics. Currently, we can only enable VSI ILMI functionality using this command.
dspvsipartcnf to display VSI partition characteristics. Currently, this command only displays information about VSI ILMI functionality.
6. There are changes in the following commands starting from Release 9.2.30:
cnfrsrc
Allow start VPI = 0 for a VSI partition on a port interface, provided there is only one VSI partition on the port interface.
Prevent second VSI partition from being enabled on a port interface if the first VSI partition uses a start VPI = 0.
Prevent a VSI partition from being disabled on a trunk interface if a PNNI controller is attached to the trunk interface controlling partition being disabled.
cnfport
Prevent disabling ILMI protocol on a port interface, if a VSI ILMI session is active on a VSI partition on the port interface.
Prevent configuring ILMI protocol on port interfaces to run on the BCC, if a VSI ILMI session is active on a VSI partition on the port interface.
cnftrk
Prevent configuring ILMI protocol on a trunk interface to run on the BCC, if a VSI ILMI session is active on a VSI partition on the trunk interface.
addshelf
Prevent adding a feeder to a trunk, if VSI ILMI session is active on a VSI partition on the trunk interface.
7. The multiple partitions introduce two VSI partitions on trunk and port interfaces on the BXM card. One partition can be used for MPLS, and one can be used for PNNI. Virtual Trunk can have only one VSI partition or can be used for AutoRoute, but cannot be used for both VSI and AutoRoute simultaneously. This project introduces six service class templates in addition to the three existing templates.
Even though tag ABR is supported in Service Class Template (SCT), neither the MPLS controller nor the BXM firmware currently support this.
The configurable VPI/VCI introduces 2 new parameters in addctrlr and addshelf commands, through which the user can specify the VPI and VCI of the master-slave control channels.
8. There is a change in reporting of port group numbers in Release 9.2.32. Previous image (MEC) of BXM used to report a 1-port group for the 2-port group cards at the channel statistics level 2 and 3. This made the port belonging to second port group unusable.
Upgrading to 9.2.30 software first and then burning the BXM card with the MED or higher firmware, BXM will report 2-port groups for 2-port cards all the time. The smooth transition between the earlier 1-port group and the newly reported 2-port groups also displays the message in dspcd "Inconsistency with logical PG #" (port group number). All earlier software will "mismatch" the card.
If the BXM card is programmed with MEC or earlier firmware revision, the channel statistics for level 2 or 3 will report 1-port group. Burning an MED or higher image will result in 2-port groups, but for backwards compatibility the software will not do the recomputation of LCNs based on the new port groups. In its logical database, this will not impact the AutoRoute connections.
For VSI controllers the reported value will be higher than the actual available LCNs. That means a VSI controller may not be able to add connection even though the available connections are non-zero. If the user wishes to remove the above discrepancy, the card must be brought to the standby mode.
Note that the newly configured card or the card in standby mode programmed with MED or higher image brought to the active state will not have above discrepancy.
9. In BPX nodes that use processor cards with 32 MB of RAM, it is possible to run out of memory in the Hitless Region. This can happen if the node is too heavily configured with cards and connections. The recommendation below should prevent memory aborts.
In nodes that have processor cards with 64 MB of RAM, there should be no Hitless Region memory problem. This is because 64 MB processors contain a second Hitless Region, which is larger than the first.
The following calculation will help prevent memory aborts on BPX processors with 32 MB. For simplicity, the numbers are approximate. It is necessary to add up the number of cards in the node, as well as the number of connections, and make sure that the total does not exceed the recommendation.
During system initialization, roughly 17,100 blocks of the available 40,000 are used for the card database.
In addition, assume that 1500 blocks will be needed for each BXM card that can support 16K connections, which is the more common configuration. Some BXM cards can support 32K connections, and these will need 3000 blocks of the Hitless Region. This chunk of memory is allocated at the insertion of the BXM card and will not be released until a card of different type is inserted.
Also, 300 blocks will be needed for each 1000 via connections on the node. This can be viewed with the user command dspload.
40000 blocks maximum total (34000 blocks for 9.2 releases up to 9.2.23)
10. The minimum software required to run MPLS are:
BPX Switch Software Release 9.2.10 or later
BXM firmware must be MEA or later
IOS Software Release 12.0(5)T (refer to IOS Release Note)
Virtual Switch Interface (VSI) 2.2
The BPX with an external 7x00 label switch controller (router) with Switch Software Release 9.2.10 and IOS Release 12.0(5)T can function as an ATM-LSR. The enhancements to dynamic label switching that was supported in Release 9.1 include support for MPLS Class of Service. The BPX as an ATM-LSR supports the "Multi-Label VC" model to support MPLS Class of Service. Five Qbins (Qbin 10-14) are reserved for MPLS Class of Service. Class-based WFQ is supported on these IP queues.
The BPX can also function as a "P" ATM-LSR in the MPLS-VPN architecture.
Hot redundancy of MPLS connections on the BPX is supported by BXM hot card redundancy. Continuous message forwarding, and keep-alive between the BXM redundant pair ensures the connection continuity on BXM switchover. On failure of a BXM card, the standby card becomes active with the label VCs. Resynchronization between the MPLS label switch controller and the BPX ensures that their databases are in sync.
11. The 16K connections feature increases the number of connections terminating on the BPX switch to 16,000. The count includes connections terminating on BXM or ASI endpoints on cards within the node as well as connections terminating on service modules in the feeder shelves connected to the BPX switch. For example, a Frame Relay connection that originates on an FRSM in an MGX 8220 connected to a BPX counts as one of the 16,000 terminated connections on that BPX.
This feature requires a BCC-3-64 or BCC-4 controller in the BPX as well as Switch Software 9.2.10 or higher.
12. Version 2.2 of the Virtual Switch Interface (VSI) provides the BPX switch with the ability to support multiple network protocols and multiple controllers per switch (for example, MPLS, PNNI, and so on). Switch resources can be dedicated to a specific controller or shared by multiple controllers.
This feature is supported on BXM ports, trunks, and virtual trunks and requires a BCC-3-64 or BCC-4 controller in the BPX as well as Switch Software 9.2.10 or higher and firmware MEA or higher.
Following are the VSI features:
Support for only one partition, that is, a port or a trunk can be partitioned into one VSI partition along with AutoRoute.
A Virtual Trunk interface cannot have both VSI and AutoRoute simultaneously. It has to be either VSI or AutoRoute only.
There are nine Service Class Templates (SCTs) defined. SCT 1 is used for interfaces exclusively for MPLS. SCT 2 and 3 are respectively used for ports and trunk interfaces, which are exclusively used for PNNI. SCT 4 onwards are used for interfaces that are used for both MPLS and PNNI.
Master Redundancy is supported, that is, multiple controllers can control the same partition.
Only one controller can be added per trunk interface.
13. The combinations of system limits such as the number of trunks, lines, ports, and connections as well as enabled TFTP interval statistics should be provisioned so that the node has at least 50 percent idle time usage. Use the command dspprfhist to verify.
14. When cost-based routing is used, increasing the cost of a trunk will result in deleting the preferred path on connections in the database if the sum of the preferred path cost exceeds the connection of configured cost. The connections will remain routed on its current path.
15. On the BXM and UXM, for the OC-3 MultiMode Fiber back cards, Y-Redundancy/hot standby is not supported due to hardware restrictions.
16. The trunk reconfiguration feature does not support IMA trunks.
Special Installation/Upgrade Requirements
General/Upgrade Procedure
Please consult your Support Representative before performing any software upgrade.
1. The earliest release supported for graceful upgrade is 9.1.03.
2. The 9.2 switch software requires MEB to MEJ firmware for BXM Model E cards.
3. Before upgrading to this release when UXM cards are to be used, certain legacy card firmware must be upgraded. See the compatibility matrix for cards affected and the exact versions to be used.
Note Standards-compliant IMA is not compatible with the proprietary IMA protocol used in
revision A firmware. Both ends of an IMA trunk must have the same protocol.
Caution Failure to follow this procedure may result in the card not operating. The card should be returned to Cisco if this occurs:
Step 1 Verify current boot code version
In order to run Model B firmware on UXM, the card needs to be running boot code revision 6 or greater. To determine the boot code running on the card, issue the following command from CLI (user must be logged in as Service level or greater to use this command):
rsh <slot #> sys version
Step 2 Upgrade UXM's boot code if necessary
The process for loading boot code is identical to the process you would use to load firmware. The only part that changes is the name of the file.
Note Burning the boot code will cause the card to reset.
Step 3 Upgrade UXM's firmware
Step 4 When Y-redundant trunks are used, the red alarm in/out values must be configured to 1.25/1.5 seconds or greater, or else INVMUX failures will occur and trunk failures will be observed during a Y-redundancy switchover. Use the following command:
cnftrkparm
This is due to the IMA protocol and may cause reroute of connections.
Step 5 Upgrade NPM software to 9.2
4. Procedure for upgrading UXM-to-IMATM trunks from proprietary IMA protocol to ATM forum-compliant IMA protocol.
Step 1 Download and burn UXM bootcode version 6 or later to all UXMs in the network. This will cause the card to reset and reroute traffic to other trunks.
Step 2 On IGX, to have firmware upgrade, issue command cnffunc 15 d to disable the UXM from resetting automatically after the firmware is burned in.
Step 3 On each MGX 8220 equipped with IMATM-B, upgrade the ASC to 5.0.10.
Step 4 Download the Forum Compliant Firmware Version IMATM5.0.10.fw but do NOT reset the IMATM-B card.
Step 5 On each IGX-UXM with IMA to be upgraded, burn firmware ABE or later to each UXM with IMA trunks.
Step 6 Simultaneously reset the card at each end of each IMA trunk to minimize trunk outage.
Step 7 Upgrade 9.1 nodes to 9.2 via loadrev and runrev.
Step 8 Issue the command cnffunc 15 e after each IGX is upgraded to 9.2.20 or later.
Note The above procedure also applies to the UXME.
5. Procedure for upgrading UXM-to-UXM trunks from proprietary IMA protocol to ATM forum-compliant IMA protocol.
Note For Y-redundant UXMs, issue the command cnftrkparm 18 100000 100000 prior to this
procedure and return to default values after this procedure.
Step 1 Download and burn UXM bootcode version 6 or later to all UXMs in the network. This will cause the card to reset and reroute traffic to other trunks.
Step 2 On IGX to have firmware upgraded, issue command cnffunc 15 d to disable the UXM from resetting automatically after the firmware is burned in.
Step 3 On each IGX-UXM with IMA to be upgraded, burn firmware ABE or later to each UXM with IMA trunks.
Step 4 Simultaneously reset the card at each end of each IMA trunk to minimize trunk outage.
Step 5 Upgrade 9.1 nodes to 9.2 via loadrev and runrev.
Step 6 Issue the command cnffunc 15 e after each IGX is upgraded to 9.2.20 or later.
Note The above procedure also applies to the UXME.
6. Procedure for upgrading BXM cards to the 9.2 firmware release.
To enable BXM cards to utilize 9.2 features, all BXM cards must be upgraded to the 9.2 firmware release. The following steps should be taken to avoid card mismatch:
For the switch running
9.1 or 9.2 or earlier than 9.2.30 switch software
BXM firmware earlier than MEB
BXM OC3/OC12 interface and the BXM is configured to channel statistic level 2 or higher.
Perform the following steps to avoid card mismatch:
Step 1 Upgrade BXM firmware to MEB.
Step 2 Upgrade BCC software to 9.2.30 or higher.
Step 3 Upgrade BXM firmware to MEC or higher (optional).
For all other cases, do the following steps:
Step 1 Upgrade BXM firmware to MEB or higher.
Step 2 Upgrade BCC software to 9.2.30 or higher.
Note See the Compatibility Matrix for the exact versions to be used.
7. Procedure for adding new BCC cards as a part of upgrading to the 9.2 release.
If new BCC cards are to be installed as part of the upgrade to Release 9.2, then the physical card upgrade procedure described below must be completed as a separate activity from the Switch software upgrade.
If upgrading to BCC-4 cards on BPX 8600 nodes, complete the software upgrade first, followed by the BCC-4 physical card upgrade. If BCC-4 is already installed then upgrade as normal.
If any other type of BCC cards are being physically upgraded, complete the physical upgrade of the cards first, followed by the software upgrade.
Statistics collection must be disabled prior to and during the software upgrade process. The disabling must be done prior to the issuing of the first loadrev command.
Statistics sampling must be disabled prior to the issuing of the first loadrev command at the start of an upgrade. (Use the service level command off1/off2, turn off line statistic sampling, port statistic sampling, trunk statistic sampling, and connection statistic sampling.)
Note See the Compatibility Matrix for the tested/supported versions of other firmware and
software that work with this release.
8. Upgrading VSI 1.1 in Release 9.1 to VSI 2.2 in Release 9.2.
Step 1 Upgrade the Tag Switch Controller (TSC)
The TSC is upgraded to the CoS VSI Version Capable Release (IOS 12.XX). This image is VSI bilingual, meaning it understands both VSI Version 1 and Version 2.
Step 2 Upgrade the BXMs
All the BXM cards in the node are upgraded to Revision E, which is VSI Version 2 and CoS capable. After each BXM card is downloaded with the Revision E image, it temporarily experiences VSI outage until the BCC software is upgraded to the 9.2.37 image. The VSI outage during the upgrade is caused by the Revision E firmware not being backward compatible with VSI Version 1 features.
Note that from the TSC perspective, after a BXM is upgraded to the Revision E image, the interfaces that used to be on the card will "disappear." The TDP sessions that were on the interfaces will be lost. When all the BXMs are upgraded to the Revision E while still running Release 9.1 software on the BCC, the node will experience a complete outage of MPLS traffic. AutoRoute will have a hitless upgrade.
Step 3 Upgrade the BCC.
As the BCC is upgraded from software Release 9.1 to Release 9.2.37, the BCC recognizes the Revision E BXMs and downloads the VSI partition configuration. This causes the BXMs to issue ifc cfg traps to the TSC, allowing the TSC to rediscover all the MPLS interfaces on the BPX. The TDP sessions are reestablished and MPLS traffic starts flowing again through the BPX.
Note The VSI 1.1 and VSI 2.2 are not interoperable.
Revision Interoperability Supported
Revision interoperating upgrades are supported, from the 9.1 to 9.2 releases of Switch software, with secondary revision incorporation for network lowest revision. This will lessen the risk of new features being enabled in a mixed network after the downgrade.
A "Secondary Revision" field in the node is used for the determination of the network lowest revision. Previous to this change, software used only the nodes primary revision.
The interoperability functionality uses network lowest revision for:
Blocking the new feature unless network lowest revision is greater than or equal to the minimum supported revision for the feature

Version Compatibility Notes
For a complete list of firmware revisions supported, see the Compatibility Matrix document, which is included in this release package.
This release will run with:
Any MGX 8220 Release 4.0, 4.1, and 5.0
Cisco WAN Manager (Cisco StrataView Plus) version 9.2
CiscoView version 2.00
UXM model ABB or later
BXM model MEB or later for Model E cards
Switch Software Release 9.2 is not compatible with UXM Firmware Model A.
Switch Software Release 9.2 is not compatible with BXM Firmware Model C or earlier.
Switch Software Release 9.2 is interworking with VNS 3.1.
DAS interworking with Release 9.2 is not supported.
Control Card Requirements
All processor cards must be configured with a minimum of 32MB of RAM. This includes BCCs and NPMs. NPMs require at least 1MB of BRAM. To verify the BRAM size on IGX 8400 nodes, use the dspcd command.
Note If any control cards contain less than 32MB of DRAM (these would be NPMs) then they
must be replaced with cards containing at least 32MB of DRAM prior to upgrading to
Release 9.2. The physical upgrade of the nodes with these control cards must be done
according to the upgrade procedure defined as follows.
Control Card Boot Firmware Requirements
As specified next, the correct version of control card (CC) boot firmware must be installed on the cards prior to a software upgrade to Release 9.2.
BCC Type
Firmware
BCC-32
H.B.J
BCC-3-32

NPM-64
R.C.S
NPM-32B
R.E.S
NPM-64B
R.F.S
With the new version of NPM boot code (RXS), the boot code upgrading does not require physical card resetting with the following steps:
Step 1 Burn the boot code on the active NPM (1).
Step 2 Execute the switchcc command and wait until the NPM(1) becomes standby. NPM(2) is now active.
Step 3 Execute the resetcd command to reset the standby (resetcd 1 h). Wait until the reset card NPM(1) becomes standby.
Step 4 Burn the boot code on the active NPM(2).
Step 5 Execute the switchcc command and wait until the NPM(2) becomes standby. NPM(1) is now active.
Step 6 Execute the resetcd command to reset the standby (resetcd 2 h). Wait until the reset card NPM(2) become standby.
Control Card Compatibility Requirements
Each redundant pair of BCC cards in a given BPX 8600 node must be of the identical type and memory configuration. That is, for example, if the active card is a BCC-3-32, then so must be the standby. BCC-3 cards with 32MB of RAM cannot be mixed with BCC-3 cards with 64MB of RAM.
Each redundant pair of NPM cards in a given IGX 8400 node must be of the identical type and memory configuration. That is, for example, if the active card is an NPM-32, then so must be the standby. NPM cards with 32MB of RAM cannot be mixed with NPM cards with 64MB of RAM. Also, NPM-64 cards cannot be mixed with NPM-64B cards.
This is a requirement for all software upgrade and downgrade procedures. It does not apply to the physical card upgrade procedure, described in the following section.
Control Card Physical Card Upgrade Procedure
When performing a control card (CC) upgrade, the following procedure must be used. This applies to all processors: BCCs, and/or NPMs.
Step 1 Remove the current standby CC front and back card. (Remove back card only applies to BCC.)
Step 2 Replace with new CC front and back cards. (Replace back card only apply to BCC.)
Step 3 Wait for the standby updates on the newly installed standby CC to complete.
Step 4 Issue a switchcc command to utilize the newly installed CC.
Step 5 Verify that the network is stable.
Step 6 Remove the current standby CC front and back card. (Remove back card only applies to BCC.)
Step 7 Replace with new CC front and back cards that are identical to the current active CC. (Replace back card only apply to BCC)
Step 8 Wait for the standby updates on the newly installed standby CC to complete.
Step 9 The CC physical upgrade is now complete.
Step 10 With the secondary card in the standby state, cause a switchover using the switchcc command. This will test that the hardware is working correctly.
Note After Step 2, the node will contain a mix of an old type CCs and the new type CCs. This
condition is permitted only while the standby updates to the new CC are in progress, which
will take less than one hour. The time during which this mixture of CC types exists must
be kept to a minimum by immediately replacing the second old type CC with the matching
one of the new type.
Obsoleted
Starting from Release 9.2.00, the IPX is no longer supported.
VSI 1.0 is no longer supported.
FastPAD is no longer supported.
The noncompliant IMA trunking (Cisco proprietary) supported in Model A of UXM firmware is not supported in Release 9.2.
Notes and Cautions
Additional Notes:
1. Switch Software Release 9.2 is not compatible with UXM firmware Model A.
2. If attempting to burn UXM firmware Model B into UXM firmware Model A with 9.2 software, the firmware Model B will not be burned into the UXM card due to the incompatibility of software 9.2 and UXM firmware Model A. The UXM has to be returned to Cisco for service.
3. If using MEC or earlier BXM firmware and upgrading to MED or later, the version of switch software has to be upgraded first so that the BXM will report 2-port groups for 2-port cards all the time. The smooth transition between the earlier 1 port group and the newly reported 2-port groups also displays message in dspcd "Inconsistency with logical PG #" (port group number). All earlier software will mismatch the card. This applied to BXM-OC3 or BXM-OC12 and configured to channel statistic level 2 or higher.
4. Firmware MED and earlier supports APS Redundancy on Legacy BXM only.
5. Because of hardware limitations, BXM hardware is not able to recognize all user-programmed cell transmission rates. Rather only discrete transmission rates can be used instead.
The equation below shows what the BXM hardware actually transmits given a user configured cell rate. The transmitted cell rate is always less than or equal to the configured cell rate. To prevent any cell loss, the transmitted cell rate must be equal to the configured rate. To do so, a cell rate must be chosen from the table below.
The rate table below lists the highest 200 cell rates supported be BXM such that if used, will result in no cell loss (given cell traffic is less than configured cell rate). Additional rates can be calculated using 1470588/[n + (1/256)], where n is an integer.
The logic to calculate the actual cell transmission rate in a BXM card is as follows:
if (configured cell rate == full line cell rate) then
transmitted cell rate = full line cell rate
else
transmitted cell rate = from equation below or from table below
Example:
If a trunk is configured at 100,000 cells per second (cps), the actual transmitted cell rate is then 98,013 cps, any traffic sent over 98,013 cps would be discarded.
If a trunk is configured at 98,013 cps, then the actual transmitted cell rate is 98,013 cps with no cell loss.
Therefore, only rates in the table should be used. Otherwise, cell loss may be experienced. The table will not be exhausted at the end but still go on with the computing from the above equation.

6. On the BPX with MGX 8220 feeder(s), regardless of the setting of the Node Parameter "42 Enable Feeder Alert," a feeder alert message will be sent to all MGX 8220 feeders immediately before a hitless rebuild takes place. The feeder alert message will temporarily disable the LMI polling from the MGX 8220 feeders. The MGX 8220 polling will resume as soon as the BPX is ready to exchange LMI messages.
7. The amount of traffic allowed on a VP tunneling connection is two-thirds bandwidth of that connection. The minimum bandwidth must be 100 cells per second. For example, a CBR connection with a peak cell rate 1500 cps then can pass traffic up to 1000 cps.
Limitations
1. BME firmware MKA and MKB is not compatible with BPX Switch Software Release 9.2x and later.
2. For Switch Software 9.2, MPLS and PNNI controllers cannot coexist.
3. In Release 9.2.30 and later, nodes might declare a communication break when using the BXM virtual trunking feature. The problem has been observed under the following conditions:
At least two virtual trunks share a common port at one node, but their remote end points terminate on different nodes.
The virtual trunks are used to carry networking (rt_op) traffic.
On the above diagram, node_B is a virtual trunk share a common port
With this topology, "node_A" sees "node_C" as unreachable and vice-versa; however, "node_A" communicates to "node_B," and "node_B" communicates to "node_C."
The problem is caused by a misprogrammed trunk networking channel. In the above example, the misprogramming occurs at "node_B." A channel that should be programmed for ingress and egress operation is programmed as egress only.
Workarounds:
BXM firmware MEH and later contains the fix for this bug (CSCdr51875).
BXM virtual trunking (no VT wraparound) can still be implemented using Software Release 9.2.20 and higher.
If virtual trunks are not yet in use, the VT wraparound solution can be implemented in release 9.2.30 and higher (CSCdr51875)
4. When the cnfrsrc command is used to delete VSI partitions on an interface, software does not check if any Soft Permanent Virtual Circuit (SPVC) connections exists on that partition. Even if there are SPVC connections on a partition, the partition can be deleted using the cnfrsrc command. The only protection is that users are provided with a warning when they try to delete the partition.
If there are SPVC connections on a partition and if the partition is deleted, the SPVC connections will be left in a undefined and unrecoverable state. Hence, before deleting a VSI partition, ensure that all the SPVC connections are deleted on that partition.
5. For UVM cards, there will be no new revisions of Model A firmware. When attempting to download Model A firmware to a UVM, software will give the user an error message indicating that the firmware does not match the card type. Note that there is no problem with continuing to use existing UVM cards running the old firmware(CSCdp08741).
6. There is a new traffic class added in Release 9.2.20 that causes a trunk parameter conflict with pre-9.2.20 node. The conflict fails adding trunk between 9.2.20 BTM/ATM and pre- 9.2.20 BTM/ATM.
All ATM traffic classes are set for BTM/ALM trunks and is hidden to the user. The introduction of rt-VBR traffic class in 9.2.20 makes it different from pre-9.2.20 BTM/ALM trunk traffic class. The user can not change the ATM traffic class for BTM/ALM trunk.
This problem exists with a new BTM/ALM trunk on an upgraded 9.2.20 node but does not exist with an upgraded BTM/ALM trunk since the rt-VBR traffic class is not set while upgrading (CSCdm64345).
7. The cloud port to which a virtual trunk is connected should have ILMI polling disabled. Otherwise, it could lead to a virtual trunk being clear on one end and declaring Virtual Trunk Path Failure at the other end (CSCdm52909).
8. In a BPX that contains BCC cards with 64MB, there is no limitation. All 12 available slots can contain BXM or Enhanced-BXM cards.
In a BPX that contains BCC cards with 32MB, a maximum of 10 legacy BXM cards are allowed. If some Enhanced-BXM cards are used in place of BXM, then each Enhanced-BXM will count as two BXM cards.
9. For performance reasons, AIS status of connections is not sent to the standby BCC. After switchcc, it may take a few minutes to update the AIS status of connections. If dspcon does not show the proper status of AIS or the dspalms screen shows an incorrect number of AIS, (after switchcc) wait for few minutes so that the status gets updated. (The dspalms and dspcon commands show the status of AIS.)
10. Hitless rebuild has similar limitations to that of a switchcc and full rebuild:
On IGX nodes, there is a four second continuity break. (Same as in a switchcc.)
There might be brief communication breaks with other nodes in the network. This will be logged in the event log of the node. There is no traffic loss or trunk failures. (This is similar to a switchcc and depends highly on the network and number of connections.)
Some line/trunk cards that are in the standby state may reset during a hitless rebuild.
The statistics that are collected by the Cisco Wan Manager will not be maintained across a rebuild.
Some will be re-enabled automatically. These include:
Auto statistics
Summary statistics
Real-Time statistics
All other statistics have to be re-enabled for collection after a hitless rebuild takes place. These mainly include the user statistics.
11. UVM cards in Y-redundancy will mismatch if one is burned with Idle Code Suppression Firmware and the other is not.
When installing/burning Idle Code Suppression Firmware on UVM pairs, the Y-redundancy must be removed, firmware in both UVM cards burned, and then the Y-redundancy can be restored.
12. Mismatch is reported when replacing a BXM card with another BXM card that has a different port group, even though both BXM cards have the identical channel number.
13. When upgrading from Release 9.1 to 9.2, the 9.1 statistics on BXM/UXM cards are supported to maintain compatibility. However, once a user configures a statistics level in 9.2, the statistics cannot be configured back to 9.1 statistics.
There is no 9.1 statistics support for BXM/UXM cards that were shipped with 9.2 firmware since the BXM/UXM card has the default level 1 statistics.
Therefore, when using a UXM with 9.2, a user must either:
Leave the statistics level untouched (this will work for UXM cards upgraded from 9.1)
OR
Set level 2 on the card
14. The BXM and UXM channel statistics level feature gives these cards the capability of collecting more than four statistics per connection. However, it is the controller card's limitations, available memory, and performance, that indicates how many statistics can actually be collected from the cards and then reported to the Cisco Wan Manager (CWM).
The BCC-3-64 can collect at most three interval statistics per connection when there are 16,000 AutoRoute (AR) connections configured on the node. (Interval statistics are those statistics that are reported to the CWM. They are often referred to as TFTP statistics.)
You can collect approximately 48,000 statistics (3 x 16,000) on the BCC-3-64. This is approximate because there are many variables that will affect this value, such as are peaks enabled, how many buckets are collected, are all connection of the same type, are trunk, line or port statistics enabled, and so on.
With this approximation of 48,000 statistics on the BCC-3-64, this then means that as a rough estimate you could enable 32 statistics on 1,500 connections, 48 statistics on 1,000 connections or nine statistics on 5,000 connections, and so on. The approximation formula being:
15. In Release 9.1, the UXM card ran a proprietary IMA communication protocol. This protocol matched that used on the MGX 8220 4 IMATM-B cards and hence could be connected together to form a trunk. In Release 9.2, standards-compliant IMA are supported on the UXM card. The standards-compliant IMATM-B on MGX 8220 5.0 is not yet released. Hence, when the network is upgraded to 9.2., the UXM will be running compliant IMA protocol and the IMATM-B will still be running the proprietary IMA communication protocol. They will no longer communicate and the trunk will fail. This will be fixed in the MGX 8220 5.0 release containing IMATM-B. However, it should be noted that an upgrade at that time will also incur some amount of downtime as there will be a difference in timing between the MGX 8220 upgrade and the switch software upgrade. There should be no effect to UXM-IMA trunks connected to other UXM-IMA trunks in 9.1 to 9.2 interoperability mode.
16. The transmit rate on an IGX IMA trunk can be altered at the local node with any trunk outage. It is possible that the transmit rates are different at the two ends of an IMA trunk. After this trunk is deleted, it cannot be added back unless the transmit rates are the same.
17. When doing a grouped upgrade from Release 9.1 to 9.2, the software error 1427 may be logged on the BPX/IGX node during a non-graceful upgrade. This error can be ignored since it is harmless to the network (CSCdm14613).
18. Reconfiguring trunk parameters might cause connections to be rerouted if the changed bandwidth load is smaller than what was used by the connections that use the trunk.
19. If LMI/ILMI is provided by the BCC:
The maximum possible number of ports on the BPX 8600 that can be configured with LMI/ILMI enabled is 52. However, each BPX will support up to a total of 16 feeder trunks and each feeder trunk will have LMI enabled. That is, if a BPX 8600 is configured with only two feeder trunks, then only (52 - 2) = 50 ports can have LMI/ILMI enabled.
If LMI/ILMI is provided by the BXM firmware:
There is no limitation on the number of ports that can have LMI/ILMI enabled.
When running ILMI on the BXM, ILMI version 3.1 WITHOUT address registration is supported.
20. Virtual Path Connections with cells whose VCI values are above 4095 will be transmitted correctly only if the path is exclusively through BXM trunks and terminate at BXM ports.
21. The feature of CIR=0 for Frame Relay connections is not supported for connections terminating between FRM cards in IGX nodes and FRSM cards in an MGX 8220 shelf.
22. SVC connections are derouted after decreasing the allocated bandwidth (increasing Statistic Reserve). It is the design intent that increasing the statistical reserve will cause SVC conns to derouted and not be rerouted (CSCst92308).
23. For the loadrev operation, it is important that the Cisco Wan Manager/TFTP buffers are maintained at their default size.
24. Due to a hardware limitation, the BNI trunk will send 13-15 percent more traffic than what it is configured for when the trunk is configured for less speed (cps) than the maximum port speed. This is especially important when the BNI trunk is connected to IMATM pairs, which carry less than T3 bandwidth.
25. When using the shift/no-shift feature on a BPX 8600 node's port card, controlled via the cnfport command, the other end of the connection must have the same setting. Otherwise, there will be a loss of continuity.
26. Due to trunk-based loading, any commands having to do with trunk loading and the load model (dspload chklm dsplm, and so on.) need to be done only after waiting a certain period of time. This time is a direct function of the trunk load update interval time (as configurable) plus the conditional update latency time.
27. The external ABR segment control loop on ForeSight (ABRFST) is an option at the user interface. It is supported by UXM-E/BXM-E but is not supported by UXM/BXM hardware. The user should not enable this option on ForeSight connections (CSCdi92451). In any case, there is no coupling between the loops.
28. The interface between a BXM feeder trunk and an MGX 8220 feeder is always considered to be an NNI interface. (CSCdj16808)
29. When adding more than 4000 connections on a BPX node, the VC polling rate must be changed to a higher interval, to accommodate the additional time needed to poll for the statistics for each VC. The cnfsysparm command, parameter 24, must be changed according to the following:
0-3999 connections
Polling Rate: 5 Minutes (or higher)
4000-7999 connections
Polling Rate: 10 Minutes (or higher)
> 8000 connections
Polling Rate: 15 Minutes
30. Given a connection that terminates on an IGX 8400 FRM at one end and an ASI on the other end, tstdelay initiated at the FRM end may not work if the ASI firmware is below the appropriate revision and does not support OAM cells as opposed to supervisory cells. This is because the updated BTM on the IGX will always generate OAM cells. Please check the Compatibility Matrix.
31. Because the detailed card error event log is not retained within BRAM, this information will be lost should a processor rebuild occur. Therefore, when issuing a dspcderrscommandon a particular slot, the display will not show the detailed card error information should a rebuild event occur. This functionality has not been modified from previous releases.
32. When a physical-layer failure (for example, LOS) is detected on the BXM, a Major Alarm is generated, and any connection routed over that port is downed (fail state). The software sends a command to the remote end of the connection to generate AIS in the egress direction (CSCdj30543).
Impact:
Since the connection is in a failed state, AIS is generated in the upstream direction (in addition to the downstream direction). Although this does conform to the letter of the I.610 standard, this is not necessarily what a user would expect to see, because it interferes with the RDI response from the end-to-end connection termination point. (A fault in the downstream direction causes a fault in the upstream direction.)
Reason for the current implementation:
The BNI can not generate AIS. If there is a fault at a BNI trunk, the current mechanism is to cause AIS to be generated by the BXM port by downing the connection. Since the BXM can generate only OAM cells from the RCMP, and the RCMP is in the ingress path, the cells must be backward routed to the egress (egress QE). Also, since end-to-end OAM cells are required, the ingress QE must be configured to drop ALL cells in the ingress path. This creates a break in continuity in the opposite direction, and AIS cells must also be generated at the other end of the same connection, in the upstream direction of the original fault.
33. There are problems in the downgrade mechanism that can cause database corruption. If a downgrade is performed immediately after upgrading, the Stby_Info revision fields are not yet filled in on the new active CC. They don't get filled in until there is an upcard response from the new locked CC. This causes a restart instead of a switchcc. If the locked CC is reset, then downgrade immediately, a restart will occur instead of a switchcc. (CSCdj30811).
34. In order to test/simulate the Y-redundant switchover of ASI T3 or E3 pairs the resetcdcommand must be used, or by pulling out the active card. It will not be correctly simulated by doing a dncd (down card) on the active card. Using dncd will cause cell discards (CSCdj08923).
35. UBR traffic gains an advantage over ABR traffic when UBR and ABR PVCs are combined on the same network. This is because UBR and ABR PVCs share the same Qbin (Class of Service Queue) on the BXM card. ABR PVCs use a flow control mechanism, VSVD, which ensures that traffic sources slow down when the Qbin usage exceeds the EFCI threshold. However, UBR PVCs do not have this throttling mechanism. Therefore, ABR will throttle back whereas UBR will not. This unfair advantage is not considered a problem, since the decision to share a Qbin for ABR and UBR traffic was intentional. Any best-effort service that one would route over UBR can be routed over ABR(VSVD), with the additional benefit of protecting resources in the network. If UBR and ABR PVCs are required then:
Option 1: Consider adding all best-effort PVCs as UBR
Option 2: Isolate the ABR and UBR paths by using cnfpref command to ensure that ABR and UBR PVCs do not share the same queues.
Option 3: To provide UBR service on a connection, rather than setting up a UBR connection, do the following:
Step 1 Set up an ABRSTD connection.
Step 2 Enable VSVD.
Step 3 Disable FCES (Flow Control External Segment).
Step 4 Disable DEFAULT EXTENDED PARAMETERS.
Step 5 Choose policing option "4" to allow access as UBR.1 (PCR policing only). This connection has ABR VSVD in the network and allows UBR.1 access. The MCR for such ABRSTD connection may be set at the minimum acceptable value of 6 cells per second (explained later to do so).
To provide ABR service on a connection, set up an ABRSTD connection, enable VSVD and enable FCES to allow RM cells to be passed to and from customer equipment. The MCR for such ABRSTD connections can be set at any user-desired value.
When the network is experiencing congestion, all the affected ABRSTD connections, regardless of the services (ABR or UBR) they are carrying, will all be throttled back at the VSVD points at the network edge. During network congestion, connections carrying UBR services are virtually stopped (to a throughput of a mere 6 cps) while connections carrying ABR services can send at a much higher, user-desired MCR. This option would avoid that UBR service gains an unfair advantage over ABR service while sharing the same CoS queue.
36. Combining Frame Based Traffic Control (FBTC) and non-FBTC connections within a Class of Service can cause FBTC connections to not receive a fair share of bandwidth. For example, if VBR connections are added at a terminating port, and some of these VBR connections have FBTC enabled while other VBR connections have FBTC disabled, the VBR connections with FBTC disabled may obtain all of the excess bandwidth before the connections with FBTC enabled receive any of the excess bandwidth. The same holds true for ABR or UBR connections. This is relevant only where FBTC and non-FBTC connections share a Qbin, either at a port or at a trunk.
37. The maximum number of VC PARMs supported: 749 for BCC-32 MB, 2,999 for BCC-64 MB. (CSCdj48589).
VC PARMs are Virtual Circuit Parameters combinations/sets. One set of VC Parameter is used for each unique Virtual Circuit that has been provisioned. Identically provisioned VCs (exclusive of end points) use the same set of parameters. Thus, on a 32MB BCC, a total of 749 uniquely configured Virtual Circuits can be provisioned.
38. Care must be taken when changing the Deroute Delay parameter, which is controlled by the cnftrkcommand. This defaults to zero, but if set to anything but zero, connection rerouting, due to a trunk failure, will be delayed as provided by the parameter.
Required Workarounds
1. When adding a node into an existing network, ensure that its node number is unique prior to a actually adding it into the network. Use the rnmnd command, and renumber the individual node while it is still stand-alone. This will make the joining of this node much simpler, and will avoid the problem of a node renumbering an active network, as described below.
2. There is a problem with node renumbering. Node renumbering (the rnmnd command) should be executed only during a stable network environment and only if absolutely necessary. A stable network environment would be, for example, one in which no connection was added for the past 30 minutes and no topology change was made in the last hour and there are no alarms or node unreachabilities. Node renumbering must be done only when the network is stable to reduce the possibility of certain temporarily blocked messages during the node renumbering process from being delivered to the wrong nodes. This would occur after the completion of the node renumbering process. It is recommended that a node be renumbered prior to being added to the network.
3. The settling time for network-wide updates can take a long time in certain situations. Specifically, the settling time for updates due to network-wide topology changes and connections in a large network when a processor switchover occurs can take a long time. The time is proportional to the number of nodes as well as the number of connections. A general estimate would be 30 seconds per node. During the period of transitions (when the updates are occurring) some network operations such as adding connections might in some cases take somewhat longer to complete.
4. When using Cisco Wan Manager, there could be a problem with communicating with a node that just had a processor switchover. The problem is within the SPARCstation itself and its caching of EtherNet addresses. It can be solved by execution the following command on the workstation as the superuser: # arp -d <node_name>
5. Users may not use the command addcon slot.1-24 v to add 24 voice connections to a CVM/UVM at once. Instead, they must separate this activity into two or more commands, so that no more than 16 connections are added at once. This is an issue only for voice connections. Data connections can be added using the "1-24" syntax. This also applies when the CVM/UVM circuit line is an E1, in which case "1-32" would apply (CSCdj14319).
6. Statistics must be disabled prior to the start of an upgrade, prior to the issuing of the first loadrev command. Statistics should be disabled from the Cisco Wan Manager, which is the Statistics collection manager.
7. Statistics sampling must be disabled prior to the start of an upgrade (usingoff1/off2), prior to the issuing of the first loadrev command. Statistics sampling state machines should be disabled from the Command Line Interface.
8. When a switchcc is executed on a BPX 8600 configured with two BCC-4 cards and contains a BXM-622 trunk card, there may be a bad clock path problem reported. It is indicated as a Minor Alarm - bad clock path. This is a transitory problem, although the alarm indication persists. To clear this, execute the clrclkalm command.
Additional Documentation
In order to take advantage of the dual SIU when upgrading to the BCC-4, the BPX 8600 node must have a new backplane which has dual traces incorporating with the BCC-4.
The command dspbpnv can be issued to verify if the node has the new backplane or the old backplane. The following chart details the bit fields for the BCC Backplane NOVRAM format, the values in bytes numbered 4 and 5 describe the back plane type.
The command cnfbpnv can be used to configure the backplane, if backplane is so enabled.

Checksum bytes - CURRENTLY NOT SUPPORTED
The peak intervals are controlled to be only those values for which peaks can be accurately collected. The rules for peak intervals are as follows:
It cannot be 0.
It must be a multiple of the polling interval.
It must be a factor of the bucket interval.
It can be the same as the bucket interval.
There are additional commands to control trunk and line loopbacks in this release:
addlnlocrmtlp <trunk> | <line>
On the node on which it is executed, it creates a loopback within the port such that the cells do not leave the card.
addlnloclp <trunk> | <line>
On the node on which it is executed, it creates a loop such that incoming cells are looped back to the other end.
dellnlp <trunk> | <line>
Removes the loopback added by either of the above two commands.
The card synchronization (Hitless-switchcc) feature can be turned on/off using on3/off3 command. For example, enter at the command line:
on3 4
This will enable the card-synchronization feature.
off3 4
This will disable the card-synchronization feature.
In order for the feature to work, the line statistics sampling should always be enabled (via on2 1 command) and the front card installed must support the card-synchronization feature. The dspcd command provides an easy way to determine whether the front card supports this new feature. If the front card supports the feature, the following message is shown on the dspcd screen:
Front card supports card synchronization
Additional debug commands are added to allow synchronization between the interface card and the CC database:
synccd <slot_number>|*
The <slot_number> is for a particular slot that supports the card synchronization feature; * For all cards that support the card-synchronization feature.
dspsyncstats <slot_number>|*
This command displays the number of connections reconciled during the synchronization process after a switchcc for different slots.
* For all slots supporting this feature.
Compatibility Notes
For a complete list of firmware revisions supported, see the Compatibility Matrix document, which is included in this release package.
This release will run with Release 4.0.0x, 4.1.0x, or 5.0.0x of the MGX 8220.

Bug ID
Description
CSCdk22430
Symptom:
Checksum word 15 of backplane nvram is not recalculated when words 0-14 are updated using cnfbpnv.
Conditions:
Observed with BPX 9.1.01.
Workaround:
None.
CSCdk45222
Symptom:
Software error 532 is logged.
Condition:
The VC pointer is not valid it is used.
Workaround:
None.
CSCdk48180
Symptom:
The bcc card is WDT reset and suddenly logs swerr52 .
Conditions:
WDT reset occurs for no particular trigger but it's rare.
Workaround:
None.
CSCdm01239
Symptom:
Feeder connections go into the A-bit failure when the hub it is connected to goes into flooded mode.
Conditions:
Happens intermittently.
Workaround:
None.
CSCdm22426
Symptom:
While using jobs to down or up the connection based on a job trigger, the job will fail if dspbob is executed while the control signal toggle.
Conditions:
Observed with IGX 8.2.56.
Workaround:
Retrigger the job after dspbob.
CSCdm60702
Symptom:
When a bus error occurs on a node, and a rebuild results, other nodes in the network will see the rebuilding node in the degraded state. This shows up as "UNDeg" in the dspnds screen. A log message will also appear on these other nodes indicating that the rebuilding node went unreachable due to degradation. The unreachability will recover automatically.
Conditions:
Only occurs if a node rebuilds due to a bus error, and degraded mode is enabled in cnfnodeparm. Will not occur if a node switches processors due to a bus error.
Workaround:
No workaround needed. No adverse effects.
CSCdm60707
Symptom:
Can take longer than expected to clear unreachability with a node that has rebuilt due to a bus error. Other nodes in the network will declare the node unreachable due to degradation ("UNDeg").
Conditions:
Only occurs if a node rebuilds due to a bus error, and if degraded mode is enabled in cnfnodeparm on that node.
Workaround:
None needed. Problem clears automatically.
CSCdp98648
Symptom:
Equipment MGR can not tell the different between BXM legacy or enhance version.
Workaround:
Log into the BPX node and do dspcd XX and determine from number of channel support. The enhanced version of the BXM card has 61K channels, and the BXM card has less than 61K channels.
CSCdr05291
Symptom:
switchIfService must be specified to delete feeder trunks, but not routing trunks.
Workaround:
Use the CLI commands to delete feeder trunks.
CSCdr25273
Symptom:
Switch software does not report an alarm as expected when AIS-Line alarm is generated on a SONET line.
Conditions:
Using test equipment during compliance testing, an AIS Line alarm is generated. The expected result is to see an AIS Line alarm on the line, have StrataView/CWM report an AIS-L alarm, see the AIS statistic incremented
Workaround:
None.
CSCdr25275
Symptom:
An RFI-Line alarm is not shown on switch software as expected when an RDI-L alarm is generated on a SONET line.
Conditions:
Using test equipment during compliance testing, an RDI Line alarm is generated on a line. The expected result is to see an RFI-L alarm on StrataView/CWM and have dsplns show an RFI-L alarm on the line being tested
Workaround:
None.
CSCdr25281
Symptom:
When an RDI-Path alarm is generated on a SONET line, switch software does not produce the expected result.
Conditions:
Using test equipment during compliance testing, an RDI-Path alarm is generated for 2 +/- 0.5 seconds on a line. The expected result is that StrataView/CWM would report an RFI-P alarm condition and the dsplns command would show an RFI-P alarm on the line
In a second test, RDI-Line was generated continuously on a SONET line. The expected results are that StrataView/CWM would report an RFI-P alarm condition and the dsplns command would show a RFI-P alarm on the line.
Workaround:
None.
CSCdr33931
Symptom:
Neither dsplog (has no record) nor CWM (receive a trap) when APS active line in Yellow alarm.
Conditions:
When APS line in yellow expected to shown in dsplog as well as trap in CWM. Introduced because of 9.2.32 fix MR 000253 (CSCdr26613) where the trunk status is set to clear if the active line is Yellow and the standby line is OK. Use dsptrks command to show the active line status and trigger trap, unless a clean and easy path to send trap without setting the trunk to the Yellow alarm status can be found.
Workaround:
Use the dspapsln command to monitor APS line status but do not reroute connections.
CSCdr45021
Symptom:
SCT 1 is the default SCT reserved for MPLS. When an SES trunk is provisioned and if the default SCT is not changed to SCT 3, the trunk will fail to come up.
Conditions:
A warning message on the configuration screen indicates that the default is SCT 1 for MPLS and should be changed to SCT 3 for SES will be useful.
Workaround:
Check that SES uplink uses SCT 3 as service template class.
CSCdr52621
Symptom:
Enabling channel statistics drops the idle time on the node to an unacceptable level.
Conditions:
Occurs when many channel statistics are enabled and/or many connections exist on the node.
Workaround:
None.
CSCdr75042
Symptom:
The remote end of FRSM to FRSM endcount the FECN when enable the NNI with FCES option
Conditions:
test set --> kiwica71 11.3.1.31 (chan 227) <--> kiwica82 11.7.12.31(BNI) <--> NNI <--> kiwica81 11.8.12.31(BNI) <-- >kiwica71 11.4.1.31 (chan 229) (loopback)
Workaround:
None.
CSCdr89767
Symptom:
Software error 945 logs continuously.
Conditions:
Ongoing failure with normal network conditions
Workaround:
None. Note that reconfiguration of nwip and lanip did not help
CSCds20977
Symptom:
Signal Degrade cleared in internal BXM states, but SWSW still shows Signal Degrade.
Conditions:
Switch software release prior to 9.2.34, and SD condition cleared from line.
Workaround:
Upgrade software to at least Release 9.2.34
Further Problem Description:
The problem exists because older switch software does not know how to interpret the "Clear SD" message coming from the new firmware. So, the firmware and SWSW states get out of synch.
CSCds21195
Symptom:
The node becomes unavailable at the U/I. Several cards removed and reinserted themselves. Software error 112 logs repeatedly.
Workaround:
Identify the faulty card using the information in the SWLOG Assistant, remove it from the node and replace it.
CSCds33823
Symptom:
After upgrading switch software from 9.1.08 to 9.2.34, 4.8 kbps connections on LDMs may fail if using DFM.
Conditions:
The failed connections are seen immediately after upgrading the switch software. It appears to happen only for connections where one endpoint is 9.1.08 and the other is 9.2.34.
Workaround:
Change the speed setting of the failed connections, or to disable DFM.
Further Problem Description:
After the connections have failed due to too many routing attempts, issue the command rrtcon <connection_id>. Afterwards, issue rrtinf. At the bottom of the screen, you will see: Reason: Rsp - inconsistent lu at endpts
CSCds34151
Symptom:
There is no specific ALARMS when node in alarm such as LOC, LOC AIS-P PATH-RDI ALL we see is 'Line A lam Type OTHER'
Conditions:
CWM (Rel.92.08), BPX (9.2.23), BXM(MFB),OC-3
1) Connect the HP tester to the BXM OC3 port and the run CWM to manage this BPX node 2) Upline and port on the BXM card 3) At HP tester generate LOP or AIS-P or PATH RDI or LOC and verify the alarm was reporting on BPX 4) At the CWM, a) launch Equipment manager, b) select BPX node c) select BXM port and right click on the selected port d) and choose 'configure' then the popup 5 At the Line configure GUI, click 'BPX PhysicalLineconfigure' select 'BPX: SONET LineConfigure'
Workaround:
None.
CSCds57049
Symptom:
Card in active-F status when 2 or more lines of the card are in major alarm.
Conditions:
2 or more lines in major alarm
Workaround:
Issue the command: resetcd [slot] f. This will only clear the status until the next time the card falls into the above conditions.
CSCds84776
Symptom:
APS is configured as 1:1. Everything works fine at the physical layer. But the switch software is not receiving update messages from the BXM firmware. The firmware reports the working and protect lines are clear but the software shows the Alarm status is in "SigDegrade BER" state. Card error on bpx04 card 13 is also generated (see description below)
Conditions:
Most of the configurable elements such as the number of connections or trunks are loaded at the switch limit. This is independent of the switch limit.
Workaround:
Down the line and then up the line. The SigDegrade alarm should clear.
CSCdt07203
Symptom:
The hitless rebuild log fills due to repeated failed switchccs.
Conditions:
A bad standby BCC is required. The node must be running at least 9.2.
Workaround:
Clear the hitless log with the command dsphitless c or switchcc less often so that the hitless rebuild log tried get a chance to age out of the log.
CSCdt26312
Symptom:
Node experiences a software error 52, watchdog abort, resulting in a BCC switchover. The software error 52 will have a data field of 23 hexadecimal. Feeders connected to the BPX will declare LMI failure on the feeder trunk and condition their connections.
Conditions:
Seen in Release 9.1 and 9.2 baseline software on the BPX. Occurs on nodes with multiple feeders that are using nwip for IP traffic to the feeders.
Workaround:
Set the watchdog timeout of the ILMI process to 40 seconds so that the switchover will occur prior to the LMI failure/connection conditioning on the feeders. Use cnfprf P ILMI E 40 to set the watchdog timer for the ILMI process, use dsperr t to verify the setting. Use an out of band solution rather than nwip for IP traffic to the feeders as this appears to be a condition of the problem.

Problems Fixed in Release 9.2.37
Following is the list of fixed problems in the 9.2.37 Switch Software release. Included with each is a brief discussion of the problem.
Bug ID
Description
CSCdk48068
Symptom:
Unable to copy UVM firmware DCA or DDA or DEC from one node to another over a trunk. Node says firmware is unavailable.
Conditions:
Observed with IGX Release 9.1.03.
Workaround:
Attach modem to node that needs DCA or DDA or DEC firmware for the UVM and download it via SV Lite. If there is a SV+ station in the network and all nodes are pingable from the SV+ with IP-relay, than tftp the firmwareimage from SV+ station to any nodes in the network.
CSCdk62907
Symptom:
Telnet access is not disabled on BPX/IPX/IGX using off2.
Conditions:
off2 18 does not work in disabling telnet access.
Workaround:
None.
CSCdp34465
Symptom:
dspcd displays BME-622-622 instead of BME-622.
Conditions:
Observed with BPX 9.1.15.
Workaround:
None. This is a cosmetic issue and does not adversely affect the node.
CSCdr17998
Problem:
UBR connections terminating at ASI-OC3 endpoints log software error 9082 when CLP is enabled or when CLP is disabled and PCR < 10 cps. Other connection types terminating at ASI-OC3 endpoints log software error 9082 when SCR < 10 cps.
Solution:
In function usr_to_int_bw(), ensure that software does not send rates less than 11 cps to the ASI-OC3 card. This solution supersedes the fix described in CSCdp51531.
Detailed Problem Description:
A previous fix removed the ASI OC3 discrete value rounding done when converting user bandwidth parameters to internal (i.e. card) bandwidth parameters. The parameter conversion is done in function usr_to_int_bw(). The fix worked as long as the user entered data rates were >= 10 cps. The PCR < 50 cps project uncovered this limitation.
To fix the problem, the user bandwidth parameters are checked to verify that they are not less than 11 cps, which is the lowest supported discrete rate value for the ASI OC3 card. If the user entered parameter is less than 11 cps, software will send 11 cps to the ASI OC3 card. The 11 cps limit checking only applies to the ASI OC3 card, and will not affect the performance of other card types
CSCdr20915
Symptom:
User attempted to cancel the resetcd command by entering "bye" at the reset type prompt and it reset the card using the arbiter option.
Conditions:
Observed in BPX 8.4.22.
Workaround:
Use the delete key to cancel the command.
CSCdr25253
Symptom:
The AIS-Path alarm is not seen on a SONET line when an Path AIS is sent to it.
Conditions:
Using test equipment during compliance testing, an AIS-Path alarm is generated. The expected result is to 1. See AIS-P reported on StrataView/CWM 2. See the AIS-P statistic incremented 3. See the line in Major AIS-P alarm
Workaround:
None.
CSCdr25273
Symptom:
Switch software does not report an alarm when AIS-Line alarm is generated on a SONET line.
Conditions:
Using test equipment during compliance testing, an AIS Line alarm is generated. The expected result is see an AIS Line alarm on the line, have StrataView/CWM report an AIS-L alarm, and see the AIS statistic incremented
Workaround:
None.
CSCdr25275
Symptom:
An RFI-Line alarm does not occur when an RDI-L alarm is generated on a SONET line.
Conditions:
Using test equipment during compliance testing, an RDI Line alarm is generated on a line. The expected result is to see an RFI-L alarm on StrataView/CWM and for dsplns to show an RFI-L alarm on the line being tested
Workaround:
None.
CSCdr51769
Symptom:
dspqbinstats shows negative values
Conditions:
When dspqbinstats overflows a certain value, the values show negative. This does not mean that there are drops or that the queue is overflowing.
Workaround:
Resetting the card clears the statistics temporarily.
CSCdr57396
Symptom:
This problem was found during code review. The possible effect of this bug is (1) the VC Q depth value may not be changed as desired and/or (2) possible abort on the node.
Conditions:
This applies only if the cnfcon command is being used on a local connection with both ends of the connection terminating on the same slot.port.
Workaround:
Do not execute cnfcon for a local connection when both endpoints of the connection are being terminated on the same slot.port. Instead, delete the connection; readd the connection and make sure to specify the required VC Q depth value during the addcon command.
CSCdr64541
Symptom:
dspcntrstats displays negative values for large real-time counters. Counter Cbrctxl has a negative value.
Conditions:
Observed on BPX with large values for real-time counters.
Workaround:
None.
CSCds15146
Symptom:
Incorrect information is being displayed when the output display is cancelled on the dspclksrcs command. While looking closely, the output that is displayed is the first clock screen over the top of the currently displayed clockscreen. redscrn will not fix.
Conditions:
Pressing cancel during the clock source display listing after the first screen.
Workaround:
None.
CSCds16812
Symptom:
When a cbr/ubr/vbr connection is programmed, the channel programming value sent to the trunk card are not correct.
Conditions:
This only happens with an asymmetrical load.
Workaround:
None.
CSCds18089
Symptom:
BPX cnfapsln displays "Signal Detect" instead of "Signal Degrade".
Conditions:
Configuring APS on BPX with cnfapsln.
Workaround:
None.
CSCds24390
Symptom:
con_verify debug command is not supported in 9.2 and higher releases.
Conditions:
All 9.2 and 9.3 Releases.
Workaround:
None.
CSCds47570
Symptom:
Through SNMP, not able to set SCR to be 6 cps.
Condition:
This is due to an invalid atmEndptSCR and atmEndptOeSCR range 7 - 1412830 specified in switch.m. it should be 6 - 1412830
Workaround:
Use CLI commands cnfcon or addcon or cnfcls if SCR has to be configured to be 6 cps.
CSCds52967
Symptom:
Secondary clock sources are hidden when a thirty fourth primary source is added to the network.
Conditions:
Addition of a new primary clock brought the amount in the network to thirty four. When dspclksrcs is issued all secondary clocks are hidden. Under secondary none is displayed. Switch Software Release IGX/BPX 9.1.19-9.1.22
Workaround:
Have less than thirty four primary clock sources configured at one time in order for the secondary clocks to be displayed correctly. This is a display problem only, the secondary clocks are still configured.
CSCds59200
Symptom:
Software error 378 logswhen issue the copycons command from the T1-IMA trunk card to the UXM-T3 card which is in standby status (no configuration on it) on IGX feeder node.
Condition:
Copycons fails as expected. But if copycons from the same UXM-T3 card to the T1-IMA trunk card, this swlog does not show up, the system gives a copycons failed message.
Workaround:
None.
CSCds61240
Symptoms:
When adding connections on a BPX node, "Unknown Response (17)" is displayed. This occurs while adding AUSM to AUSM connections.
Conditions:
On the remote end, 1) Sum of minutes is exceeding the port speed. 2) Total number of connections are exceeding the number of connections that are allowed for the configured polling rate. BPX nodes running Release 9.3.10 MGX PXM firmware running 1.1.31 AUSM running 10.0.20.
Workaround:
Change the pooling rate to 10 minutes which allows up to 8000 connections by using cnfsysparm command.
CSCds64587
Symptom:
copycons allows atfx connections to be added on FRM card which does not support atfx connections.
Conditions:
Observed on IGX. addcon cannot add atfx connections to FRM card while copycons can.
Workaround:
None.
CSCds66268
Symptom:
copycons does not generate a valid warning message.
Condition:
Switch Software Release 9.2.35 executing copycons with template connection having parameters set to generate a warning message. (like high PCR is set for an ATFR connection between UXM and FRM on IGX)
Workaround:
None.
CSCds66861
Symptom:
Connections stop routing across a UXM trunk when the configured gateway connection limit is reached. By increasing the number of gateway connections supported on the trunk you can only route further connections until the gateway connection limit is once again reached. Then no further via connections will route and they report the failure as unable to find route. There is sufficient bandwidth and conid's to support the remaining failed connections.
Conditions:
UXM trunk card with CGW and SGW connections preferred routed across it. Found in SWSW 9.1.19 and UXM BBJ on E3 trunk cards.
Workaround:
1.Down one of the connections that is a gateway connection on the trunk that has reached its limit for gateway connections.
2.Wait for all the failed connections to reroute and come to normal status.Add new via connections if required.
3.Up the connection that was downed in the first step.
CSCds69729
Symptom:
The following symptoms are all related to this defect:
On IGX, tstconseg performs the entire number of iterations when the abort flag option is SET and the test fails.
On BPX, the default value for the abort flag is "NOT to abort" but tstconseg stops at first encounter of failure when the abort flag option is not specified.
Conditions:
On IGX: The following conditions are needed for this problem to occur. 1) tstconseg is run on a connection with the abort flag option SET and Loop count > 1. 2) The test fails for the connection.
On BPX: The following conditions are needed for this problem to occur. 1) tstconseg is run on a connection with Loop count > 1 and the abort flag option is not specified. 2) The test fails for the connection.
Customer Impact:
1) On IGX, the test should abort after the first failure. Instead, it continues until for the entire count, blocking other commands and wasting CPU time. 2) On BPX, the test should continue after the first failure when the abort flag option is not specified. Instead, it stops and user may not know if the test will succeed on a retry.
Workaround:
Set loop count = 1. With SW Release 9.2.37, this is not fixed on BPX, tstconseg passed on DAX connections.
CSCds72447
Symptom:
Cost-based route recovery allows route to exceed connection cost cap.
Conditions:
Cost-based routing could not find a path for the connection. New route calculated exceeded the connection cost cap yet the connection routed. Observed in 9.1.24 and 9.2.35.
Workaround:
Possible workarounds include using cnfpref to specify a preferred route. This will provide a route for the connection. Cost-based routing can be disabled using cnfcmparm. Also, the trunk cost can be tuned with cnftrk. The connection cost cap can be configured with cnfrtcost.
dspctrlrs output is truncated, it does not display the header "Intfc Type", rather it just displays the header "Intfc" and truncates the "Name" of the feeder. dspctrlrs output in BPX does not wraparound if more than one screen of controllers are added. The CLI neither queries the user for displaying more output nor the display is clear.
Condition
This problem is seen only in BPX and the screen display is cluttered only when the number of controllers exceeds 12 to display more than one page.
Workaround
None. dspnode can help to identify the feeders and their type.
CSCds82339
Symptom:
When a graceful upgrade is done on an IGX node, the idle time of the node may be reduced to < 10% for a long time. The TRNS task takes > 50% of the CPU. After this period of time, the node functions normally.
Condition:
This happens only if there are ATFR connections on the IGX node with the FR side as the master end of the connection. The more ATFR connections with FR as the master on the node, the longer the TRNS process takes a lot of the CPU.
Workaround:
Do a cnfcon on all the ATFR connections with FR as the master end-point and modify at least one of the BW parameters.
Further Problem Description:
This problem happens because of a inconsistency between the BW parameters of the ATFR connections stored on the ATM side (can be IGX or BPX) and the FR side. This discrepancy arises only if the connection is added from the IGX node (on the FR side). When doing swithcc/upgrade, the master node will send BW updates of all its connections to all the slave nodes. If the slave node detects any discrepancy, it will respond back with a BW Change request. If there are large number of connections with this discrepancy, a BW change request is generated by the slave node for each of those connections - and these messages are processes by the TRNS task on the master node, thus utilizing many CPU cycles.
CSCds84556
Symptom:
An "L" is displayed in the IGX dsppwr screen in the status field.
Conditions:
Observed on IGX with DC power and the power supply is in "OK" state.
Workaround:
Ignore the "L", it has no meaning.
CSCds86393
Symptom
cderrors record wraparound function does not work in IGX and BPX.
Condition
This occurs when the cderrors record wraparound function is enabled using cnffunc.
Workaround
None.
CSCds88748
Symptom:
After upgrade, the software does not indicate UXM card LCN resync capability even if the card has this capability.
Conditions:
The problem only happens when the firmware is upgraded first. If the software is upgraded first and firmware upgraded later, this does not happen.
Workaround:
dncd/upcd fixes the problem.
CSCds89338
Symptom:
dspload shows negative load when a prefer path connection is routed.
Conditions:
The load for vbr/abr has to be asymmetrical. A connection with asymmetric load say ms/sm. If the trunk does not have enough ms trunk bandwidth but enough sm bandwidth, the connection still routed. But the ms direction in the dspload shows negative load.
Workaround:
None.
CSCdt01430
Symptom:
NWIP traffic is not delivered, other CC traffic is delivered as expected
Conditions:
The logical trunk number of a feeder equals the slot number of a BXM virtual trunk and CC traffic is using the virtual trunk. While Y redundancy is not a condition of the problem, if the virtual trunk is Y redundant both physical slots of the Y redundant pair must be evaluated for the stated condition. The problem is specific to BXM virtual trunks.
Workaround:
1. Do not use virtual trunks or if you do, restrict CC traffic on all virtual trunks that meet the condition of the problem.
2. Use wraparound virtual trunks. The BCC self-test must be disabled if on a release prior to 9.2.34 as CSCds62320(duplicate of CSCdp46785) will cause loss of traffic on wraparound virtual trunks.
3. Make sure that there is no feeder with a logical trunk number that is equal to the slot number of any virtual trunk. This requires moving the feeder trunk or the virtual trunk(s) if the problem already exists on the node.
CSCdt04146
Symptom:
BPX logs software error 923 during copycons command.
Conditions:
copycons with starting channel endpoints at virtual trunks (invalid endpoints). Observed in BPX 9.2.34.
Workaround:
Avoid copying connections with invalid endpoints.
CSCdt04849
Symptom:
Memory corruption may occur as the software image downloads while the firmware image downloading is in progress through TFTP.
Condition:
This occurs only while downloading the software image while firmware image download is in progress.
Workaround:
Download the software image after finishing the firmware image download.
CSCdt04852
Symptom:
1. CWM does not recognize back card removal on IGX and BPX nodes for cards in active state.
2. Feeder object counter is incremented on dspsvmsg display, whenever an active card object robust message is sent.
3. Deactivating an active empty card in IGX does not remove card info in CWM display.
4. When a secondary y-red card is removed or y-red is deleted notify CWM about the secondary card status too.
Condition:
Problem "1" occurs for active cards only.
Workaround:
None.
CSCdt15193
Symptom:
Node aborts with a software error and abort error of 3000000 after issuing the rsh command.
Conditions:
This is a very rare, defect, never actually observed, but discovered during a code inspection. If the node has nearly all of its memory allocated, or the memory regions are extremely fragmented then it is possible that invoking the rsh command would cause the node to abort.
Workaround:
To be sure that enough memory is available, invoke the command dspprf r t and validate that the combined delta between the columns "Blocks" and "Allcd" for DYNM, STTC, POOL, HIT1, PL02 and HIT2 are at least 100 and that dspmemblk shows that the "maximum block in bytes" for DYNM, STTC, POOL, HIT1, PL02 or HIT2 is 4k or larger (only one needs to be 4k or larger).
CSCdt24344
Symptom:
BPX command srstats shows field "Stby Bus Errors" continuously incrementing.
Conditions:
Observed on BPX 9.2.33 on a BCC4 node without a standby BCC.
Workaround:
Ignore srstats "Stby Bus Errors" if standby BCC is not in standby state and not mismatched.
CSCdt24454
Symptom:
When a card fails in a node running 9.2.XX software, the alarm is logged in the alarm logs but there is no Minor Alarm seen in the bottom right hand corner. This should occur if there are no previous alarms in the node.
Workaround:
None.
CSCdt35981
Symptom:
UXM card fails the loopback test.
Condition:
A disconnected cable on a UXM OC-3 trunk card or line card or an LOS condition due to intermittent physical line failure.
Workaround:
Enter resetcd XX f to clear the problem, or disable the loopback test by using the command cnffunc 1 d.
CSCdt37502
Symptom:
FTM connections are auto deleted on the master side (UVM/CVM side) when a switchcc is performed.
Conditions:
IGX with Switch Software Release 9.2.34/36 FTM-UVM/CVM connections after one/two switchcc
Workaround:
None.
CSCdt49018
Symptom:
An 1M3 abort occurs on IGX (or HW watchdog time-out on older 32M NPMs) after changing the node number from 39 to any other number.
Conditions:
Using rnmnd to change a node number from 39 to any other number while IGX is running Switch Software Release 9.2.20 or later.
Workaround:
Renumber the node prior to adding it to the network. Under no circumstances should a node be renumbered from 39 to some other node number while an IGX with an affected SWSW release is in the network. Consequences include aborts and inconsistent databases, possibly resulting in the deletion of the renumbered node from the network.

2. ITUT Annex B and configurable Signal Degrade (SD) and Signal Failure (SF) thresholds for SONET Linear APS on BXM-OC3 and BXM-OC12 (1+1, 2 card, 1:1).
The current default thresholds are as follows:
BIP count
Condition
10^-4
SF detected
10^-5
SD detected & SF clear
10^-6
SD clear & SF clear
New Features Supported in BXM Firmware MDA
1. Support for Virtual Trunking
2. Support for BXM Multi-Level Channel Statistics
3. SONET Linear APS on BXM-OC3 and BXM-OC12 (1+1, 2 card, 1:1)
4. Support for card based LMI and ILMI
Clarifications
1. The OC-3 MultiMode Fiber backcards do not support Y-cable redundancy.
2. Upgrade from VSI 1.1 to VSI 2.2 is supported in this release. See upgrade section on page 9.
Special Installation/Upgrade Requirements
BXM cards with M.C.B/M.D.A firmware or later can be smoothly migrated to the M.E.H version of firmware by using y-cable redundancy. To upgrade a BXM card pair in y-red configuration, first upgrade the standby card with the MEJ firmware version and wait for all the configuration to be downloaded into the card. Do a switchyred to switch to the card with firmware M.E.F and burn the other card also with M.E.H firmware. Follow the standard firmware upgrade procedure for downloading and burning the firmware into the cards.
Features Obsoleted
VSI 1.0 is obsoleted by VSI 2.2 in this release.
Notes and Cautions
1. M.E.E is fully compatible 9.2 Switch Software. It has not been tested for compatibility with 8.4, 8.5, or 9.1 Switch Software. It is compatible with IOS version 12.05t2 for MPLS
2. While upgrading firmware on OC3 or 2-port OC12 BXM cards whose statistics level is greater than 1 (command dspnovram "Number of Channel stats: shows 12 or higher"), the upgrade should take place according to one of the procedures below to avoid the card mismatch.
Upgrading from firmware revision MEA or higher:
Step 1 Switch software should be upgraded to 9.2.30 or higher.
Note Switch Software Release 9.1.x can be used with MEx firmware if VSI is not enabled.
Step 2 Upgrade the firmware to MEJ.
Upgrading from firmware revision lower than MEA:
Step 1 Firmware should be upgraded to MEC
Step 2 Upgrade the Switch Software to 9.2.30 or higher revision.
Note Switch Software Release 9.1.x can be used with MEx firmware if VSI is not enabled.
Step 3 Upgrade the firmware to MEJ.
3. Burn firmware should not be interrupted. Card resets in the middle of burn firmware will result in the BXM being maintained in the core state (Identified by blinking yellow LED), or failed state (Identified by a solid red led). In this case the dspcds screen will report the card as FAILED. This state can be recovered by reburning the firmware into the card.
4. Protection Switching based on BER on BXM may not comply to standards. The GR-253 & ITU-T G.783 requires that switching be completed within 60 msec from the time the error starts. BXM is unable to detect BER threshold crossing until the next poll, which occurs every 250 msec. Thus, switching time may be up to 250 msec under certain circumstances.
5. In APS 1+1 default configuration, both backcard LEDs show green when primary card is active and selection is from PROT line. When primary card is active and it is selecting from PROT, PROT backcard should be green, since it is carrying traffic. WORK backcard should also be green since that is the physical path for the primary (and active) card to pass traffic. So backcard LED green means the backcard is directly or indirectly carrying traffic and pulling the backcard will cause traffic disruption. (CSCdm53430)
6. In APS 1+1 default configuration and a manual W->P is on and a switchyred is issued, a manual W->P event is logged. By default, on switchyred the new active card comes up in "clear" state. But in this case since there is a manual W->P on, the APS line switches to PROT and the switching is logged. (CSCdm53404)
7. In APS 1+1 default configuration if the selected line is PROT and last user request is clear and a switchyred is issued, line switches to WORK. If the last user request is "clear", full automatic APS switching is in effect with the working line being active by default. When there is no last user switch request to switch to any particular line, the working line will become active. (CSCdm53420)
8. When APS Annex B is added to local end which has the Secondary card active, the APS trunk goes into Comm Failure for few seconds and then clears. If Secondary card is active, then do a switchyred to make Primary card active and then add APS Annex B. (CSCdm46359)
Known Anomalies
The following is the list of known anomalies for the BXM firmware.
Bug ID
Description
CSCdp32247
Symptom: switchapsln/dsplog show no alarm at all but Popeye show alarms
Conditions:
CSCdp05098
Symptom: Cell discards occur for ABRFST/ABRSTD conns when the traffic burst is greater than the MBS
Condition: This occurs when the traffic burst size is fixed to 140000 cells at 70000 cps. The conn are configured with PCR=72000/72000, MBS=1000/1000 and ICR 7200/7200. This is the expected behavior since the configured MBS < the actual burst size.
Workaround: Increase the MBS and ICR using cnfcon.
Bugs Fixed in MEJ
The following bugs are fixed between MEH & MEJ.
Bug ID
Description
CSCdr19696
Symptom: User never gets to know when the line is out of SD/SF condition.Both the aps lines always show in OK state in dspapsln.
Condition: APS Line switches to standby line because of SD/SF condition. dspapsln will still show OK for both the lines. This way, user will never get to know when this line has come out of SD/SF condition.
Workaround: Use rsh command to get all the aps line's status.
CSCdp87443
Symptom: The APS switch to working lines after finished burned FW.
Conditions:
Workaround: Upgrade to MEJ or newer version firmware
CSCdr55491
Symptom: Disconnect the working line of APS 1:1 lines will cause the active line is protective line and it is working fine after APS line switching.major alarm (Path Unavailable Secs.) on the trunk or line via this APS line pair.Also, the active APS line has the alarm "Path Unavailable" even the real.
Conditions: This problem only happens in 9.3 and APS 1:1 mode.
Workaround:
1. addapsln to APS 1:1 mode and uptrk or upln using upped APS line.
2. make sure the active line is working line, if not, switchapsln to manually switch it.
3. pull out the Rx cable of working line. the APS switching should happen.
4. the active line should be protective line after switching.
5. the "Active Line Alarm Status" is "Path Unavailable" and the trunk or line has major alarm "Path Unavailable Secs."
6. pull back the Rx cable of working line, alarms is gone.
CSCdp67775

Description
CSCdp58969
Symptom: cb_get.c CB_VPC_STATUS_POLL SoItcSend Failed upon VSI Failure
Condition: When VSI receives and transmits lot of VSI message AAL5 drive will get into deadlock problem if it had missed a DMA interrupt
Workaround: None. Upgrade to MEF or newer version of firmware
CSCdp57596
Symptom: CB_TASK on BXM goes into deadlock state causing VSI session to be lost
Condition: This happens when both Ingress and Egress qe semaphore is taken by IDLE_TASK and it never released in an error condition
Workaround:. None. Upgrade to MEF or newer versions of firmware.
CSCdp25220
Symptom: Avail Buffer on BXM = 0 on LVC flapping for xtag interfaces
Condition: Same as CSCdp58969. During this condition AAL5 driver doesn't release the transmission buffer.

CSCdp39723
Symptom: Aps not functioning in 9.2.21 w/FW ME18@sprintf for Bidirectional w/Nonrevertive
Condition: Reversion was happening due to spurious SF/SD events.Fixed by setting the right values for SF/SD thresholds
Workaround:None.Upgrade to MEF or newer version of firmware
CSCdp20848
Symptom: SF switchover does not occur after dncd/upcd execution on Annex B 1+1 APS
Condition: When the dncd command is executed, Switch Software sends 0x27 CBUS message. The handler for this message was putting the lines in loopback and shutting down the laser. Also it was changing the line state in SoCdDown() to DOWN state. This caused subsequent upcd (0x05/0x04) message to re-initialize the lines disabling the S/UNI interrupts in the process.
Workaround:None.Upgrade to MEF or newer version of firmware
CSCdp24224
Symptom: WTR does not occur after LOS recovery on protection line
Condition: The meaning of primary and secondary channels were changed immediately upon switchover instead of waiting for the expiry of WTR. This caused the clearing of the failure to be accounted against the secondary channel and thus there was no WTR. Fixed by introducing a Preparation switch mode where-in the current active channel will remain as the secondary until a WTR occurs or a primary section mismatch pre-empts that state. At the expiry of WTR, the preparation switch mode is complete and the current active channel becomes the primary.
Workaround:None.Upgrade to MEF or newer version of firmware
CSCdp32646
Symptom: WTR Timer does not work and reversion occurs during SF switchover
Condition: Added a preparation switch mode where the current active channel is the secondary channel. At the expiry of WTR, the secondary channel is changed to the become the primary channel.
Workaround: None.Upgrade to MEF or newer version of firmware
CSCdp35156
Symptom: BPX APS reverts back to the working line before WTR time has expired
Condition: TR was being pre-empted by a spurious SD condition. Fixed by setting the right thresholds for SF/SD based on BER
Workaround:None.Upgrade to MEF or newer version of firmware
CSCdp60696
Symptom: Both lines fail when only one line in alarm
Condition: After the standby card comes out of reset, its S/UNI states are not reliable for a period of 1.5 seconds and the S/UNI reports LOS clear on the WORK line. This gets conveyed to the active card and then the Manual switch gets priority and becomes the current local request. This causes a switch back to WORK. When the active card's S/UNI monitors the WORK line, it discovers that the line is in LOS and immediately switches back. The oscillations continue and the line goes into LOCKOUT due to excessive switching. In the Lockout mode only the WORK line is active and thus the defect.
Workaround:None.Upgrade to MEF or newer version of firmware
CSCdp65320
Symptom: Need a trap when BPX puts APS in lockout
Condition: Send the traps in the right sequence. First send the Lockout trap and then the failed to switch trap if there is a switch attempt while lockout is in effect.

CSCdm50659
Symptom: Trunk alarms are not generated when random bit errors are injected onto a trunk using an Adtech Sx14 test set at a rate of 10E-3. There are trunk statistics generated but no trunk alarm because the statistics that cause alarms on do not meet the threshold for MAJOR or MINOR alarms.
CSCdm50659
Symptom: Trunk alarms are not generated when random bit errors are injected onto a trunk using an Adtech Sx14 test set at a rate of 10E-3. There are trunk statistics generated but no trunk alarm because the statistics that cause alarms on do not meet the threshold for MAJOR or MINOR alarms.
Condition: This was generated in a lab environment with test equipment that was set to inject bit errors randomly through the entire bandwidth. Some HCS errors were generated as well as Path unavailable and Path Farend unavailable.
Workaround: Lowering the alarm threshold for MAJOR and MINOR HCS errors can help to generate a trunk alarm. Use the cnflnalm command and modify the Hcserr alarm thresholds to.01 for MAJOR and.0001 for MINOR. These thresholds are as low as they can be set currently.

Workaround:
CSCdp00063
Symptom: Node unreachability is experienced on VTs (virtual trunks)
Condition: Multiple VTs are configured on a trunk interface of the BXM/BXM-E
Workaround: configure only one VT per trunk interface
Logic to calculate actual cell transmission rate in a BXM card is as follows (CSCdm94372):
if (configured cell rate == full line cell rate) then
transmitted cell rate = full line cell rate
else
transmitted cell rate = from equation below or from table 1
example:
if a trunk is configured at 100,000 CPS, the actual transmitted cell rate is then 98,013 CPS
any traffic sent over 98,013 CPS would be discarded.
Therefore, only rates in the table or computed from the equation should be used.
Otherwise cell loss may be experienced.

Bugs Fixed in MEB
The following is the list of bugs fixed in release MEB.
Bug ID
Description
CSCdm50469
Symptom:
Software error 105 and malloc card errors happened continuously
Condition:
When jobs that cause reroutes of connections (e.g. switchcc, hitless rebuild) are run for a long time, sometimes BXM card freezes with malloc card errors and software error 105.
Workaround:
None
CSCdm50723
Symptom:
After deleting APS, switchyred causes temporary LOS when the other end still has APS.
Condition:
One end has APS 1+1, other end was added with APS 1+1 and line is up between the two ends. Then APS is deleted from one end. The primary card is active on non APS end. On switchyred on the non APS end there is a temporary LOS. If APS was never added to one end, then switchyred does not result in temporary LOS.
Workaround:
Instead of deleting APS first and then doing a switchyred, do a switchyred first and then delete APS. This does not result in temporary LOS.
CSCdm63038
Symptom:
BXM card fails with breakpoint error.
Condition:
When tx cell rate of a trunk is reduced to zero, BXM card fails with break point error (division by zero).
Workaround:
None
Bugs Fixed in MEA
The following is the list of bugs fixed in release MEA:
Bug ID
Description
CSCdm09882
Symptom:
Log non fatal message related to RCMP errors.
Condition:
It is mainly seen in the heat chamber.
Workaround:
None
CSCdm18186
Symptom:
AIS status could be randomly be displayed in dspcon
Condition:
When the connection AIS signal is constantly changing, the dspcon/dspchstats OAM status will not be accurate for all the connections on the card.
Workaround:
None
CSCdm26380
Symptom:
Software error 9098 occured during switchyred BXM
Condition:
This problem occurs on cards with the APS channels halved option set and then doing a cnfrsrc on a port that belongs to the second port group. Note that this fix will cause a card mismatch on active cards with channel halved option turned on.
Workaround:
None
CSCdm31923
Symptom:
AIS/YEL alarm doesn't go away even after the alarm is clear from the other end.
Condition:
It happens on the E3 when the LOOP TIME parameter is set to YES in the trunk or line configuration.
Workaround:
None
CSCdm37519
Symptom:
Trunks go to Communication Fail after burning firmware.
Condition:
When MC10 is burnt into BXM-OC12 with trunks.
Workaround:
None
CSCdm37709
Symptom:
APS line fails to clear channel mismatch after lockout.
Condition:
Bi-direction APS 1+1. Local end has locked out of protection set. Then WORK cable is pulled out on local end to cause LOS. Lockout is then cleared and then the WORK cable is put back. This causes a channel mismatch on the far end and the mismatch never clears.
Workaround:
None
CSCdm38647
Symptom: This bug has been fixed in MEA such that the firmware reports the correct number of port groups. The side effect of this fix is that the Switch Software could mismatch the BXM card. If there is a card mismatch then down all the lines/trunks on the card and up them again.
Condition: When the user loads the MEA firmware on the BXM card running MDA with APS halved channeled enabled, then the card will come up in mismatched state.
Workaround:
None
CSCdm46658
Symptom:
switchapsln command does not work for APS AnnexB line.
Condition:
Annex B configuration if hitless rebuild is done when active line is PROT, then switchapsln does not work after hitless rebuild.
Workaround:
None
Bugs Fixed in MDA
The following is the list of bugs fixed in release MDA:
Bug ID
Description
CSCdm38647
Symptom:
MDA fw may report incorrect number of port-groups when APS channels are set to halved.
Condition:
When user attempts to add all the channels available on the card on one port-group, it may be allowed even though the BXM may not have enough memory to support it. Also, this may cause a mismatch state when MDB firmware is burnt.
Workaround:
Down all the line/trunks on the card and up them again.
CSCdm23713
Symptom:
VI numbers are not modified by firmware.
Condition:
When one or more trunks are failed in the network, there may be a combreak in the network.
Workaround:
Set all the Virtual trunks to restrict CC traffic.
CSCdm23827
Symptom:
APS alarm may clear on switchyred.
Condition:
After a switchyred, an existing a LOS/LOF alarm may get cleared. This will only happen when the line has switched to protection before the card switchover is performed.
Workaround:
None
CSCdm23752
Symptom:
BXM fw does not allow a networking channel on VTs to configured for egress only.
Condition:
BXM fw allowed configuration of networking channel to be bidirectional only.
Workaround:
None

Appendix B
UXM ABL Firmware Release Notes
ABL is a new firmware release for the UXM card on IGX. Firmware is the same for UXM and UXM-E cards.
New Features
Flash memory drivers are upgraded to support more flash memory vendors so that more flash manufacturers can be used to source components.
Obsolete Features
None.
Compatibility
Software
ABL firmware is compatible with Switch Software 9.1 and 9.2
Hardware
ABL is compatible with UXM and UXM-E model H/W all models.
Previous Versions of UXM Firmware
On IMA trunks this version is not compatible with UXMs Model B firmware versions ABA to ABD.
On IMA trunks Model B firmware (AB*) is not compatible with model A (AA*) because model B is Standards compliant and model A is not. So IMA trunks must be upgraded together.
Bugs Fixed in this Release
Bug ID
Description
CSCds08193
Symptom:
Although the trunk operates fine, the dspportstats will show the old delay value even though the actual delay on the line is different. IMA trunk statistics will not show the correct delay value when the delay is toggled rapidly.
Condition:
Whenever the delay is changed rapidly on one of the links in an IMA group the dspportstats on that trunk is not updated. The errors seen are related to the SX/12 tester operation. No errors are seen when the SX/13 is used.
Workaround:
Change the delay with gaps of approximately a minute between changes.
Upgrade Instructions
Upgrade boot code to boot 07 before upgrading to ABL.
Notes and Cautions
This firmware enables flash components from multiple new vendor to be used. Previous versions of firmware cannot write on to these new devices. For new cards with the flash devices from new vendors, firmware cannot be downgraded to versions prior to ABL. If this is attempted, burnfwrev will fail leaving firmware revision ABL in the flash.
Boot Code Requirements
Boot Code revision boot_07 is needed for the ABL release.
