Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
interface Virtual-Template201 ip unnumbered loopback201
CSCso74257
Symptoms: Memory leaks may be seen.
Conditions: The symptoms are observed when running Cisco IOS Release 12.2S and when QoS is
configured for ISG IP sessions.
Workaround: There is no workaround.
CSCso74503
Symptoms: Ingress QoS does not work on the port-channel EVC after line card OIR.
Conditions: While doing the OIR, there are some race conditions possible. QoS does not get applied
on EVCs.
Workaround: Remove and apply policy back on each EVC.
CSCso74843
Symptoms: The standby may hang during boot, and the master enters ACTIVE-DRAIN mode.
Conditions: This may occur during aggressive session bring up or session churning and switchovers.
Workaround: There is no workaround.
Further Problem Description: A full reload is required to reset the system and get back to SSO
HOT-STANDBY mode.
CSCso74937
Symptoms: In an HA setup, the active-RP may crash. Eventually, the active-SP may crash as well.
Conditions: The symptoms are observed with a repetitive overnight ES40 linecard reset.
Workaround: There is no workaround.
CSCso75048
Symptoms: The following error message is displayed:
IPC-SP-2-ONINT: Invalid operation at interrupt level
Conditions: Occurs while processing IPC messages for the platform multicast configuration and
following the online insertion and removal (OIR) of the ES20-10GE line card.
Workaround: Currently this error message is shown when the platform multicast subsystem tries to
send too many IPC messages due to corruption in its database. Hence, a subsequent OIR or interface
flap will not solve the issue. A redundancy force-switchover can be performed to recover from the
issue.
CSCso75456
Symptoms: All the output packets are dropped at RSPAN destination interface.
Conditions: Occurred while testing RSPAN with Etherchannel as destination on the Cisco 7600
router. There are no output packets on the port-channel interface which is configured as destination,
although the MAC address table entry is found.
Workaround: Perform a shut/no-shut of the port-channel interface after it is configured as the
RSPAN destination interface.
CSCso75863
Symptoms: A service policy is not attached at SIP400 when attached under a virtual template in
distributed link fragmentation and interleaving (dLFI) over ATM (dLFIoATM).
Conditions: The symptom is observed with any type of QoS on a SIP400 with dLFIoATM.
