What is cmFlowHistoryACLA2NDrop?
This counter tracks the number of frames or packets dropped due to Access Control List (ACL) rules applied in the a2n (access-to-network) direction on a specific flow. When packets match an ACL deny rule, they are counted here before being discarded. Network operators review this to verify ACL enforcement and identify unexpected traffic filtering.
