Description (partial)

On an ASR 9000 ethernet or enhanced ethernet linecards, non-initial fragments of a packet incorrectly match to an MQC class-map, when that class-map uses an ACL with l4 port info.

This may happen in uncommon conditions where the payload data of the fragment immediately following the IP header corresponds to the L4 port info in the class-map's ACL.

For IPV6 egress packets on enhanced ethernet linecards, this may also occur when a very recent previous packet through the system has L4 info corresponding to the L4 port info in the class-map's acl.
