This document describes Cisco IOS Release 11.3WA4, up to and including Release 11.3(9)WA4(12). Release 11.3(9)WA4(12) is based on Release 11.3. These release notes are updated with each maintenance release of the Cisco IOS software, which is typically every six weeks.
Note These release notes describe Release 11.3WA4 for the Catalyst 5000 series Route Switch
Module (RSM) and Cisco 4500, 4700, 7200, and 7500 series routers only. They do not describe
features or caveats for Release 11.3 or other ED releases. For a list of Release 11.3 software caveats
that apply to this release, refer to Cisco IOS Software Release 11.3 and 11.3T Caveats. For Cisco
IOS release notes that apply to this release, refer to Release Notes for Cisco IOS Release 11.3. These
documents are located on the Documentation CD-ROM and CCO. For more information, see the
"Cisco Connection Online" section on
page 17 and the "Documentation
CD-ROM" section.

Open Caveats—Release 11.3(11)WA4(14)
There are no open caveats for Release 11.3(11)WA4(14).
Open Caveats—Release 11.3(10)WA4(13)

There are no open caveats for Release 11.3(7)WA4(10).
Open Caveats—Release 11.3(6)WA4(9)
There is one open caveat for Release 11.3(6)WA4(9):
CSCdk26488
Many dmac-synch errors can cause the RSM to stop receiving packets. Symptoms of the defect include not routing packets, as well as not being able to session into the RSM.
Workaround. When the defect occurs, the error condition will persist until you reset the C5IP backplane interface. Enter the test rsp stall command to reset this backplane interface and clear the error condition.
Open Caveats—Release 11.3(5)WA4(8)
These are the open caveats for Release 11.3(5)WA4(8):
CSCdk27849
In some situations the Catalyst 5000 series switch returns an incorrect IP address for the RSM, which prevents CiscoView from working properly.
Workaround. There is no workaround.
CSCdk26488
Many dmac-synch errors can cause the RSM to stop receiving packets. Symptoms of the defect include not routing packets, as well as not being able to session into the RSM.
Workaround. After the defect occurs, the error condition will persist until you reset the C5IP backplane interface. Enter the test rsp stall command to reset this backplane interface and clear the error condition.
Open Caveats—Release 11.3(4)WA4(7)
There is one open caveat for Release 11.3(4)WA4(7):
CSCdk19752
If an IPX RIP request packet does not receive a reply from the router, it will stay in the input queue and not be released. Accumulated packets could cause the input queue to fill causing severe problems for all protocols.
The RIP request will not be answered if the following occurs:
Requested network is not in the table, and no default route exists
Requested network is denied by an output filter
Requested network is split horizoned (the network was learned on the same interface that the request came in on)
Resolved Caveats—Release 11.3(11)WA4(14b)
These caveats are resolved in Release 11.3(11)WA4(14b):
CSCdp26283
Under certain config sequences a 'no mls rp ip' issued on an interface can cause the router to crash. This caveat is now resolved.
CSCdm67708
When enabling global mls rp ip on a Draco with a large configuration of HSRP pairs, the following message is displayed at the console at about every 15 seconds:
00:19:30: %SYS-2-BADSHARE: Bad refcount in datagram_done, ptr=61B31B58, count=0
This caveat is resolved in Release 11.3(11)WA4(14a):
CSCdm92277
An intermittent hardware problem on the RSM might cause the C5IP (the interface processor that connects to the Catalyst 5000 backplane) to fail. The following message appears:
When this occurs, the RSM has to reload the C5IP microcode, which causes all VLAN interfaces to go down for 30 to 90 seconds. No packets are forwarded during this time.
This ddts enhances the error-processing routines in the C5IP, which allows it to recover from the error in most circumstances. The RSM will continue running with no interruption in service.
Resolved Caveats—Release 11.3(11)WA4(14)
There are no resolved caveats in Release 11.3(10)WA4(14).
Resolved Caveats—Release 11.3(10)WA4(13)
There are no resolved caveats in Release 11.3(10)WA4(13).
Resolved Caveats—Release 11.3(9)WA4(12)
There are no resolved caveats in Release 11.3(9)WA4(12).
Resolved Caveats—Release 11.3(8)WA4(11)
There are no resolved caveats in Release 11.3(8)WA4(11).
Resolved Caveats—Release 11.3(7)WA4(10)
This caveat is resolved in Release 11.3(7)WA4(10):
CSCdk26488
Many dmac-synch errors can cause the RSM to stop receiving packets. Symptoms of the defect include not routing packets, as well as not being able to session into the RSM.
Workaround. After the defect occurs, the error condition will persist until you reset the C5IP backplane interface. Enter the test rsp stall command to reset this backplane interface and clear the error condition.
Resolved Caveats—Release 11.3(6)WA4(9)
This caveat is resolved in Release 11.3(6)WA4(9):
CSCdk27849
In some situations, the Catalyst 5000 series switch returns an incorrect IP address for the RSM, which prevents CiscoView from working properly.
Workaround. There is no workaround.
Resolved Caveats—Release 11.3(5)WA4(8)
This caveat was resolved in Release 11.3(5)WA4(8):
CSCdk19752
If an IPX RIP request packet does not receive a reply from the router, it will stay in the input queue and not be released. Accumulated packets could cause the input queue to fill causing severe problems for all protocols.
The RIP request will not be answered if the following occurs:
Requested network is not in the table, and no default route exists
Requested network is denied by an output filter
Requested network is split horizoned (the network was learned on the same interface that the request came in on)
Resolved Caveats—Release 11.3(4)WA4(7)
These caveats are resolved in Release 11.3(4)WA4(7):
Under very heavy traffic, the LAN Emulation Client (LEC) occasionally goes down and up, with the Last Fail Reason always given as the Control Distribute Virtual Connection (VC) being released. This problem is fixed in Release 11.3(4)WA4(7). (CSCdk28312)
The LEC does not listen to its own TOPOLOGY REQUEST messages. When a topology change occurs, the LEC does not use the short aging timer if it is on the designated bridge of the Emulated LAN (ELAN). This problem is fixed in Release 11.3(4)WA4(7). (CSCdk30340)
When MPOA is configured on a Catalyst 5000 series ATM module or on a router port along with the Simple Server Redundancy Protocol (SSRP), shutting down the ATM interface can crash the router or Catalyst 5000 series ATM module. In addition, the ATM module or router can crash when the fiber connecting the ATM module to the switch is unplugged. This problem is fixed in Release 11.3(4)WA4(7). (CSCdk34153)
Supported Port Adapters
Table 3 lists the port adapters supported in Release 11.3WA4.
Table 3 Supported Port Adapters
Port Adapter
Product Number
PA-8T-232 Synchronous Serial
PA-8T-232
SA-Comp/1 and SA-Comp/4 Data Compression Service Adapter
This section lists caveats that apply to port adapters used in the Catalyst VIP2:
If you are using the High-Speed Serial Interface (HSSI) single- or dual-port adapter in the Catalyst 5000, 5500, 5505, or 5509 switch, you must install the port adapter on the Catalyst Versatile Interface Processor 2 (VIP2-15 or VIP2-40) Revision 2 (board part number 73-3468-XX, where XX is the version number). Do not use the HSSI single- or dual-port adapter in the Catalyst 5000, 5505, or 5509 switch if you are installing it on a Catalyst VIP2 (either VIP2-15 or VIPS-40) module that is not Revision 2. If you fail to comply with this restriction, your system will shut down due to an overload of the power supply.
You can only have two HSSI single- or dual-port adapters per chassis when installed on a VIP2-15 or VIP2-40 module Revision 1 and used in the Catalyst 5500 switch.
The Channelized T1 port adapter (PA-2CT1/PRI) interfaces require shielded serial cables and connectors.
