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: The issue can be avoided by not applying service policies to the subinterface directly
and instead applying the service policies under the PVC configuration. Shutting down and restarting
the affected interfaces is required to clear the issue.

Symptoms: A CHSTM1 controller TUG-2 E1 remote alarm does not clear until the controller is shut
down. This symptom happens only on an unframed E1.
Conditions: The receiver must be receiving a remote alarm, while the E1 framing is changed from
framed to unframed.
Workaround: Enter the shutdown command and then the no shutdown command on the controller
to clear the remote alarm condition.

Symptoms: A 4xOC3 ATM ISE line card stops process packets in the small buffers queue (80 byte
queue). All traffic ceases and the ATM PVCs configured over the line card is set to a down/down
state. Resetting the LC clears the buffers and resolves the issue, but it reoccurs. There appears to be
a slow leak or alternately sporadic bursts of traffic with malformed 80-byte packets that fill the
buffer and cause the issue to reappear.
Conditions: This symptom has been observed with Cisco IOS Release 12.0(32)S3.
Workaround: Micro-reload of line card solves the issue temporarily, but it reappears.
CSCsf32676
Symptoms: Output rate limit is not working for the new rate limit configured for the interface.
Conditions: This happens when an egress line card used does rate limit in the slow path (e.g.: Engine
0 line card). This occurs only when a new rate limit configuration is added after the router is brought
up. If the rate limit on the egress is already present during the router bringup, then the issue will not
be observed. When Engines that implement rate limit in hardware like E3/E5 are used as the egress,
then the issue will not occur.
Workaround: The ingress line card would need to be reset for the new output rate limit configuration
on the egress to take effect. If the rate limit on the egress is already present during router bringup,
then the issue will not be observed.
CSCsf99490
Symptoms: The ACL actually applied on a line card interface is different than what is configured on
the RP.
Conditions: This symptom has been observed when changing ACLs with the ip access group
command applied to interfaces of a line card very quickly. The following examples shows the initial
configuration and the configuration which has this symptom.
Initial configuration:
interface GigabitEthernet 2/0/0
ip access-group 116 in
interface GigabitEthernet 2/0/1
ip access-group 116 in
interface GigabitEthernet 2/0/2
ip access-group 116 in
interface GigabitEthernet 2/0/3
ip access-group 115 in
Changed configuration with issue:
interface GigabitEthernet 2/0/0
ip access-group 115 in
interface GigabitEthernet 2/0/1
