Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: The show mpls traffic-engineering tunnel command output may indicate "Removal
Trigger: setup timed out" status.
Workaround: Perform a shut/no shut on the interface or change the metric temporarily to force an
update with the tunnel mpls traffic-eng autoroute metric 1 command.
CSCsk67466
Symptoms: PVC may not come up on the ATM main interface.
Conditions: The symptom is observed on a peer-to-peer (P2P) sub-interface that is configured for
PVC.
Workaround: There is no workaround.
Further Problem Description: On a P2P sub-interface configured for PVC, allow the PVC to come
up. Then delete the subinterface and recreate the same PVC on the main interface. The PVC does
not come up (stays in INACTIVE mode). Spurious memory access may also be seen in this process.
CSCsk68320
Symptoms: A switch aborts or reloads after the no ip routing command is entered.
Conditions: This symptom is observed when a Supervisor Engine IV is configured with a minimal
IP multicast and Multicast Source Discovery Protocol (MSDP) configuration. This problem occurs
when msdp timer is set to 1.
Workaround: There is no workaround.
CSCsk68846
Symptoms: Router Crashed when removing grandchild policy
Conditions: Seen on a Cisco 7304 Router.
Workaround: There is no workaround.
CSCsk71117
Symptoms: The topo_name on the upgraded version remains null, causing XDR to become disabled.
All features that use XDR as their distribution mechanism will not work.
Conditions: Software upgrade (ISSU) from SB9 to SR, that is, from pre-MTR release to post-MTR
release.
Workaround: There is no workaround.
CSCsk75147
Symptoms: A cbs3120 switch may crash during license installation, while reloading the slave switch
that is being installed with license.
Conditions: This symptom is observed when:
1. Installing up to 10 licenses in one file on Slave 4 in one vty session. 2. Reloading Slave 4 while
installing the license on another vty session.
Workaround: There is no workaround.
Further Problem Description: The issue is related to Inter-Process Communication (IPC). The crash
is due to accessing an already freed port info. But the crash may be prevented by adding a check
atcipc_notify_session_closure.
CSCsk75986
Symptoms: A multilink bundle may go down when ACFC and PFC configurations are applied.
Conditions: The symptoms are observed under a multilink interface on CPE and virtual-template on
LNS.
