Caveats
Resolved Caveats—Cisco IOS Release 12.0(33)S1
Symptoms: Packet drops on output service policy after port swap in Tx BMA of E3 Card. The
problem is due to the port-burst being changed incorrectly without any real configuration change on
the concerned sub-interfaces.
Conditions: When a Port-swap in Tx BMA is accompanied by the change in burst value after
removing service policy (or sub-interface), we are able to see the traffic drop to another
sub-interface.
Workaround: Remove and re-add the output service policy from the affected sub-interface.
• CSCsl96577
Symptoms: The show ppp multilink statistics are not updated on a Cisco 7500 router.
Conditions: This symptom is observed when dLFIoLL+SSO is configured on the Cisco 7500 router
and a switchover is performed.
Workaround: There is no workaround.
• CSCsl98882
Symptoms: Traffic stops forwarding after the deletion of a security output ACL which is shared with
the other port on a two-port OC-192, with the port carrying the traffic having a feature-output ACL.
Conditions: Occurs on a two-port OC-192 E6 card. Both the ports should be configured with output
or input security ACLs, and one port which is carrying the traffic should have output or input ACL.
For this issue to happen, all the ACLs need to be either output or input type simultaneously.
Workaround: Configure a new ACL with a different name from the original ACL, then remove it.
The traffic can then be forwarded again.
Further Problem Description: This issue is specific to E6 alone and will not happen on E4.
