Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• SNMP access of cltcDot1qTunnelMode might cause a reload. This problem is resolved in
Release 12.1(13)E3. (CSCdz35749)
• The implementation of the CISCO-SLB-EXT-MIB on the Catalyst 6500 series switches and
Cisco 7600 Series Routers does not support the “SET” operation. When a user attempts a “SET”
operation on the following objects, the system tries to free unallocated memory and generates
traceback messages:
–
cslbxServerFarmHashMaskAddr
–
cslbxServerFarmClientNatPool
–
cslbxServerFarmHttpReturnCodeMap
–
cslbxVirtualURLHashBeginString
–
cslbxVirtualURLHashEndString
This problem is resolved in Release 12.1(13)E3. (CSCdz54807)
• If the length field in the MSDP TLV is less than the minimum MSDP TLV size (3 bytes), memory
corruption might occur and cause the system to reload. This problem is resolved in
Release 12.1(13)E3. (CSCdz25339)
• A system with an MSFC2 running a c6msfc2-jsv-mz.121-11b.E4 software image may run out of
memory and reload. The show version command output may indicate that the system returned to
ROM monitor mode. The stack or crash-information log might not be saved. Occasionally after the
reload, free memory in the processor pool may start to decrease. IP input is the process that might
be using the additional memory. This problem is resolved in Release 12.1(13)E3. (CSCdz18419)
• Cisco IOS SLB does not support RPR+. If you configure Cisco IOS SLB with redundant supervisor
engines, you need to configure RPR. This problem is resolved in Release 12.1(13)E3.
(CSCdz25527)
• The switch processor may reset because of memory corruption when a race condition occurs
between two multicast processes This problem occurs when a multicast router port’s hold timer
expires and the port link status goes down almost immediately. Both processes try to delete the
multicast router port from its database at the same time. This problem is resolved in
Release 12.1(13)E3. (CSCdz47758)
• In rare situations, a system running IOS 12.1(8a)E5 may reload with a bus error after you enter the
ip verify unicast reverse-path command on an interface. This problem is resolved in
Release 12.1(13)E3. (CSCdw20764)
• The system may reload because of memory corruption. This problem occurs when SNMP is set to
the snmp-set smonVlanIdStatsTable elem 64-bit counter. This problem is resolved in
Release 12.1(13)E3. (CSCdw50718)
• If an RPR+ switchover is performed while traffic is forwarded, you may see L3-PS-DRVR switch
processor messages on the console. This problem is resolved in Release 12.1(13)E3. (CSCdw71753)
• The hardware FIB may point to an incorrect adjacency entry when a recursive lookup is involved.
You can resolve this problem by entering a clear ip route * command, which builds the hardware
forwarding and adjacency tables again. This problem is resolved in Release 12.1(13)E3.
(CSCdx93111)
• The ifOutDiscard counter is updated incorrectly on WS-X6548 LC modules. This problem is
resolved in Release 12.1(13)E3. (CSCdz02952)
• Because of a race condition, a (*,G) flow may not be completely switched in hardware. Traffic and
forwarding capabilities remain unaffected. This problem is resolved in Release 12.1(13)E3.
