Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
CSCsu92966
Symptoms: Send statistics from the show mpls l2 vc command are not displayed.
Conditions: Occurs on a PE when the other PE’s core-facing link is flapped.
Workaround: Perform a shut/no shut on the SVI interface.
CSCsu93374
Symptoms: The group state of a slave group may unexpectedly change to Active after an RP
switchover.
Conditions: The symptom is observed when HSRP multigroup is configured such that a slave group
follows the state of a master group. If the HSRP group state is Standby, then the group state of the
slave group may change to Active after an RP switchover.
Workaround: There is no workaround.
CSCsu94030
Symptoms: Internal VRF gets disabled at when the router boots up.
Conditions: Occurs after any failover or router start-up scenario
Workaround: Use the no platform ivrf disable to avoid the issue.
CSCsu94720
Symptoms: Router crashes when the shutdown command is used on an interface.
Conditions: Occurs when there are DHCPv6 bindings.
Workaround: There is no workaround.
CSCsu94864
Symptoms: The MLS shortcut for a user-traffic flow based on RADIUS Framed-IP (FIP) is not
purged when the FIP sticky times out. RADIUS Load Balancing (RLB) sends out a purge request
before deleting sticky and has no effect in deleting the MLS shortcut entry.
Conditions: Occurs on a device configured with RLB and FIP sticky idle timer and with MLS aging
timer configured higher than the RLB FIP sticky idle timer.
Workaround: There is no workaround.
CSCsu95080
Symptoms: A router remains in the init_process state when parsing the configuration.
Conditions: The symptom is observed when an IPv6 multicast group joins without MLD configured.
When the groups unjoin, the system suspends.
Workaround: Configure MLD.
CSCsu95171
Symptoms: In switches running Cisco IOS Release 12.2(33)SRC, high CPU may be seen on the
SP/DFC due to NDE-IPv4 process. This may result in following unrelated problems:
- Corrupted file system(s)
- show running command may show “read error” etc.
- Continuous CPUHOGs automatically disabling Cisco Express Forwarding (CEF).
Log Messages reported:
%SYS-SP-3-CPUHOG: Task is running for (4000) msecs, more than (2000)msecs
(2/0),process = NDE - IPV4.
Conditions:
