Conditions: This was observered on a Cisco 7600 with Supervisor 720 running Cisco IOS Release
12.2(33)SRB3 after a ATM sub-interface was removed.
Workaround: There is no workaround.
CSCsr86826
Symptoms: A standby SP may experience a memory leak in the mls-hal-agent process.
Conditions: This has been experienced on a Cisco 7600 router with dual SUP720s running either
Cisco IOS Release 12.2(33)SRC or Cisco IOS Release 12.2(33) SRC1. The router is configured for
multicast.
Workaround: There is no workaround.
CSCsr96042
Symptoms: ASR1000 Router crashes.
Conditions: Occurs if "ip vrf" is deleted from the configuration.
Workaround: There is no workaround.
CSCsr97343
Symptoms: An MSDP peer may flap randomly.
Conditions: The symptom is observed when the device is configured with logging host ip-address
... or logging host ip-address.
Workaround: It has been observed that removing the "logging host" configuration helps in
preventing the peer-flap: no logging host ip-address no logging ip-address
CSCsr97753
Symptoms: Pinging an interface fails.
Conditions: Occurs when unconfiguring xconnect on the interface.
Workaround: Perform a shut/no shut on the the interface.
CSCsr98731
Symptoms: If running OSPF, stale routes may be installed in the RIB. Also wrong paths (inter-area
vs intra-area) are preferred.
Conditions: Occurs on a router running Cisco IOS Release 12.2(33)SRC1.
Workaround: There is no workaround.
CSCsu04088
Symptoms: With unidirectional Ethernet (UDE) enabled on ES20 port, UniDirectional Link
Detection (UDLD) gets disabled. But on converting the port from L3 to L2 (or vice versa) or on
shut/no shut of interface, UDLD is enabled again on the interface. Once UDLD gets enabled, due to
the UDE feature, the port is detected as unidirectional and put to err-disabled state.
Conditions: Occurs on ES20 ports configured for both UDE and UDLD.
Workaround: Disable UDLD on the port.
