Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Symptoms: Router may crash when “show tracking brief” is entered if one or more tracking object
have been created using the Hot Standby Routing Protocol (HSRP) cli, such as standby 1 track
Ethernet1/0.
Conditions: This does not occur if all tracking objects use the new track command as follows:
track 1 interface Ethernet1/0 line-protocol interface Ethernet 0/0 standby 1 track 1
Workaround: Use show tracking instead, or configure tracking with the new command.

Symptoms: IPv6 address of loopback interface set as passive under Intermediate
System-to-Intermediate System (IS-IS) router process is not present in IS-IS database.
Conditions: Issue is seen when loopback interface is set as passive under router IS-IS configuration
and the IPv6 address of the interface is only added afterwards. If the passive-interface command is
used when the loopback interface already has its IPv6 address configured, issue is not seen.
Workaround: After the IPv6 address is configured under the affected interface, remove and add the
passive-interface configuration under the router IS-IS process.
