Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S5
Workaround: Enabling CEF or fastswitching should avoid the problem.
CSCsf07966
Symptoms: Router may reload when both fastswitched and CEF switched packets and process-level
packets are congesting an interface that has QoS enabled.
Conditions: The symptom is seen when the traffic consists of large packet size greater than 512 bytes
and is reported on PA-4T/8T+ interface only. It is not seen on channelized interfaces.
Workaround: There is no workaround.
CSCsf10205
Symptoms: An ISE OC48 or 4xOC12 channelized card may display the error message:
EE48-3-QM_ERR_DECODE: FrFab QM_TX_ERRORS qm_oqdq_halted
This error will reset the forwarding and queueing ASICs resulting in small traffic disruption.
Conditions: This symptom occurs when the ports are dynamically channelized and/or
unchannelized.
Workaround: Micro-reload the line card after channelization or unchannelization.
CSCsf11182
Symptoms: The output of the show policy-map interface interface-name vp vpi input command
for an ATM interface does not show anything and states that the policy is not configured. However,
the output of the show running-config command does show the service policy for the ATM
interface.
Conditions: This symptom is observed on a Cisco router after an RP switchover has occurred twice.
Workaround: There is no workaround.
CSCsf12388
Symptoms: Packets may reach incorrect destination during MPLS TE Tunnel Flaps.
Conditions: An LSP being reoptimized causes a label to get reused. This may cause the packet to be
switched to an incorrect destination for a brief period. This brief period, usually about 1 or 2
seconds, is the time taken for the label for the old prefix to be withdrawn from other routers. It
should be noted that the label reuse doesn’t always occur.
Workaround: There is no workaround.
CSCsf17284
Symptoms: Keep the T1 controller in the ìupî state, and when reloading the router in the running
configuration after the router comes up, the T1 controller has been shut down.
Conditions: This symptom has been observed on Cisco IOS Release 12.0(32)S and
Release 12.0(32)SY.
Workaround: To bring the T1 controller up, use the no shutdown command on the controller. There
is no workaround.
CSCsf22278
Symptoms: Incorrectly attaching a service policy under the ATM subinterface and then re-adding
interfaces with service policies will cause the latter interfaces to not have QoS applied. This can be
avoided by correctly adding service policies under the PVC configuration only.
Conditions: This symptom has been observed when applying service policies to the subinterface
directly.
