Description: Counter of L3 control protocol frames dropped due to acl no match.
What is cmEthernetTrafficPortHistoryAclDropNoMatch?
This counter records the number of Layer 3 control protocol frames dropped on this port during the archived historical interval because they matched no configured ACL rule. A historical review helps the admin date exactly when an ACL gap began silently blocking control-plane traffic, such as routing protocol hellos, on this port. For example, if a routing adjacency failed to come up after a config change last week, the admin would check cmEthernetTrafficPortHistoryAclDropNoMatch from that date to confirm the ACL was the cause.
