Resolved Caveats—Cisco IOS Release 12.0(27)S5
• CSCeg66282
Symptoms: The controller of a 1-port multichannel STM-1 port adapter (PA-MC-STM1) does not
come up after the router has reloaded.
Conditions: This symptom is observed on a Cisco 7500 series that runs Cisco IOS
Release 12.0(28)S2. The symptom may also occur in other releases.
Workaround: There is no workaround.
• CSCeg66627
Symptoms: An Engine 6 line card may reset because of an IPC timeout and may generate the
following error message:
%MCC192-3-CPUIF_ERR: Packet Exceeds Programmed Length
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(27)S3.
Workaround: There is no workaround.
• CSCeg73076
Symptoms: A Cisco 10000 series reloads when a large QoS policy is defined.
Conditions: The symptom is observed when you define a policy map that exceeds the number of
classes that can be defined in a policy (32).
Workaround: Avoid policies with an unsupported number of classes.
• CSCeg79456
Symptoms: An Engine 6 line card may reset because of an IPC timeout.
Conditions: This symptom is observed on a Cisco 12816 that runs Cisco IOS Release 12.0(27)S4
when you enter the shutdown command on the primary Clock Scheduler Card (CSC) or you enter
the no shutdown command on the secondary CSC that is in the shut down state.
Workaround: There is no workaround.
• CSCeg83399
Symptoms: When an ATM PVC is configured with an egress service policy, exiting from the PVC
configuration mode by entering the exit command may cause traffic that is forwarded from other
PVCs on the line card to be dropped.
Conditions: This symptom is observed on a Cisco 12000 series router that is configured with an
ATM ISE line card or an 8-port OC-3 ATM Engine 2 line card.
Any action that causes the affected ATM PVC to be reinitialized restores traffic forwarding.
Workaround: Do not enter the exit command to exit from the PVC configuration mode. Rather, enter
the end command.
• CSCeh00169
Symptoms: After you have reloaded a router, for each of the service policies that are attached to the
interfaces of a 4-port OC-12 POS ISE line card, the policing of L2 VCs may fail when errors with
the following associated error messages occur:
"Must remove existing service policy first .."
or
"Configured exceed actions are not supported when policing L2 VCs on interface.."
When the policing of L2 VCs fails, the following error message is generated:
"L2 policing config failed."
