  • Cisco Network Convergence System 5500 Series

Known Affected Releases

6.3.2.BASE

Description (partial)

Symptom:
Egress IPv4/IPv6 ACL is not supported on sub-interfaces in 6.3.2.

Conditions:
Egress IPv4/IPv6 ACL is not supported on sub-interfaces in releases prior to 6.3.3.  Prior to 6.3.3: 
 - egress IPv4 ACL would be applied to the main interface that contains sub-interfaces, which works
 - egress IPv6 ACL would be applied to the main interface that contains sub-interfaces, which works unless HQoS is enabled. If HQoS is enabled, then the traffic would not be treated by the egress IPv6 ACL. 

To address the issue with egress IPv6 ACL with HQoS being enabled, a change is being introduced to allow the egress (IPv4/Ipv6) ACL to be attached to the sub-interface rather than to the main interface.
