Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: This problem occurs when keepalive tunnels are configured for manual L2TP sessions.
Workaround: There is no workaround.
CSCsl52594
Symptoms: When two routers are configured to form an IPv6 EIGRP adjacency, attempts to ping
one of the loopback IPv6 addresses from the neighbor fails with the following error:
No valid source address for destination
Conditions: Occurs on routers running Cisco IOS Release 12.4T.
Workaround: There are two workarounds:
1. Disable IPv6 Cisco Express Forwarding (CEF) 2. Enter the clear ipv6 eigrp neighbor command
CSCsl53110
Symptoms: A Standby RP may crash during SNMP bulk synchronization with errors in Community
MIB.
Conditions: The symptoms occur in a corner case. They may be seen during SNMP bulk
synchronization of Community MIB, having communities with ACLs. Community entry, while
being synchronized, is still pointing to deleted ACLs which leads to the Standby RP crashing at the
time of bulk synchronization.
Workaround: There is no workaround.
Further Problem Description: This is a rare scenario which is applicable in VS setup with NAM card
present.
CSCsl53494
Symptoms: The error messages generated for the SSC-400 card display incorrect product name.
Conditions: Occurs in log messages. Product is incorrectly referred to as SSC-600 rather than
SSC-400.
Workaround: There is no workaround.
CSCsl54243
Symptoms: A SIP-400 will crash on a Cisco 7600 series router after inserting an SPA then removing
a VLAN subinterface.
Conditions: This symptom is observed on a Cisco 7600 series router with a SIP- 400 line card
running Cisco IOS Release 12.2(33)SRA5. VLAN subinterfaces that exist prior to inserting an SPA
will cause the SIP to crash if they are unconfigured after inserting another SPA.
The specific steps that cause the SIP-400 to crash are:
1. Configure a VLAN subinterface on an SPA.
7600(config)#int gi 2/0/0.100
7600(config-subif)#encap dot1q 100
2. Physically insert another SPA into the SIP-400.
3. Unconfigure the subinterface and observe the SIP-400 crash.
7600(config)#no int gi 2/0/0.100
Workaround: There is no workaround.
CSCsl54889
Symptoms: When ISG is configured as a DHCP relay and the DHCP client is rebooted or if the
DHCP client sends a DISCOVER packet in error, ISG is unable to process subsequent DISCOVER
packets.
