Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Symptoms: Protocol Independent Multicast (PIM) VPN routing/forwarding (VRF) neighbors not
formed.
Conditions: Occurs after line card reload.
Workaround: Delete and add back the MVPN configuration.

Symptoms: In scaled conditions (8000 IP sessions) with SACL applied, line card memory leaks over
a period of 4-5 hours. Sometimes this even results in a line card crash. The "Sacl Np Client" task
occupies most of the CPU, and a large number of IP sessions (around 10% of 8k) will be in feature
pending status, with ACL pending flag set.
Conditions: Occurs under scaled conditions with approximately 8000 IP sessions, with the same
SACL applied to all IP sessions.
Workaround: There is no workaround.

Symptoms: Cisco router crashed while Intermediate System-to-Intermediate System (IS-IS) is
coming up.
Conditions: Occurred only on a Cisco router running Cisco IOS Release 12.2(33)SRC2 with ’mpls
traffic-eng multicast-intact’ configured under ’router isis’.
Workaround: disable ’mpls traffic-eng multicast-intact’ configuration.

Symptoms: Following a processor switchover in route processor redundancy (RPR) plus mode, the
SM-1CHOC12/T1-SI card on the channelized serial interfaces goes down.
Conditions: Occurs after the processor switchover in RPR plus mode.
Workaround: Use hw-module reset to solve the issue.

Symptoms: Features requiring nas-port as a username determined by AAA (such as pre-auth) will
not work on the standby device, causing standby sessions to be poisoned.
Conditions: AAA calculates the IP address of the best port, which is up and active. However, on the
standby device, no interface is visibly active, resulting in a best IP address defining the router to be
0.0.0.0.
Workaround: There is no workaround.

Symptoms: Multicast rate-limiters stop working after a HA switchover.
Conditions: To see this issue you have to have a HA setup with multicast rate-limiters set. In order
to see this issue the rate-limiters must have been set before the standby is booted. If the rate-limiters
are set after standby is up in HOT state, the issue is not seen after switchover.
Workaround: Remove and reconfigure the rate-limiters.
• CSCsu83588
Symptoms: After a router reload, the Flex Link configuration (switchport backup interface Po#)
is lost.
Conditions: Occurs when a backup interface is a port-channel interface.
Workaround: There is no workaround.
