Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S6
Conditions: This symptom is observed rarely when all of the following conditions are present:
There is a very brief (shorter than 500 ms) interface flap on a point-to-point interface such as a
POS interface.
The flap is not noticed by the neighbor, so the neighbors interface remains up.
The OSPF adjacency goes down and comes back up very quickly (the total time is shorter than
500 ms).
OSPF runs an SPF during this period and, based on the transient adjacency information,
removes routes via this adjacency.
The OSPF LSA generation is delayed because of LSA throttling. When the LSA throttle timer
expires and the LSA is built, the LSA appears unchanged.
Workaround: Increase the carrier-delay time for the interface to about 1 second or longer.
Alternate Workaround: Use an LSA build time shorter than the time that it takes for an adjacency to
come up completely.

traffic-eng autoroute announce command is enabled.
Conditions: This symptom is observed on a Cisco router that also has the mpls traffic-eng
multicast-intact command enabled.

CSCef08173
Symptoms: A VIP in which a PA-2FE port adapter is installed may reload because of memory
corruption that is caused by a hardware issue of the PA-2FE port adapter.
Conditions: This symptom is observed when the VIP and port adapter function under stress, when
the VIP is unable to serve memory read/write requests from the port adapter, and when there are PCI
retry timeouts.
Workaround: There is no workaround.

Symptoms: Removing a policy that has shape and bandwidth in the same class (in that same order)
may cause a router to crash.
Conditions: This symptom is observed when the router functions under a traffic load.
Workaround: There is no workaround.
