Description (partial)

IPv6 CoPP ACL matches traffic incorrectly. Packets are not matched against IPv6 ACE of "permit icmp any any echo-request" or against "permit icmp any any echo-reply". This causes traffic to be classified incorrectly.

This symptom occurs with recent Cisco IOS images. Results are as expected on Cisco IOS Release 12.2(33)SRE9a. However, it is broken in Cisco IOS Release 15.2(4)S onwards.
