Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S3
• 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.
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, can 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 with an E3 ATM or E2 8xOC3
ATM line card installed.
Any action to cause the affected ATM PVC to be reinitialized will restore traffic forwarding.
Workaround: Do not enter the exit command to exit from the PVC configuration mode. Rather, enter
end command.
• CSCeg88655
Symptoms: A RP switchover causes %SYS-2-NOTQ and %SYS-2-LINKED errors and some
tracebacks on a Cisco 12000 series 1-port channelized OC-12c/STM-4 (DS1/E1) ISE line card.
Conditions: This symptom is observed on a Cisco 12000 series dual-PRP router that runs a
Cisco IOS interim release for Release 12.0(31)S.
Workaround: There is no workaround.
• CSCeg89202
Symptoms: When you attach a policy with a priority class to a subinterface of a channelized
OC-48/STM-16 (DS3/E3, OC-3c/STM-1c, OC-12c/STM-4c) POS/SDH ISE line card that is
configured with Frame Relay subinterfaces, the default queue limit for the priority queue of the port
changes to a value that is calculated by the policy map that was attached. This situation causes QoS
to be impacted.
Conditions: This symptom is observed on a Cisco 12000 series.
Workaround: Ensure that the policy map that you attach last calculates the desired queue limit,
which is then applied to all subinterfaces of the port.
