Cisco Bug: CSCul11613 - Non-initial fragments may match class-maps with l4 port info
May 13, 2018
- Cisco ASR 9000 Series Aggregation Services Routers
Known Affected Releases
Symptom: 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. Conditions: 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.
