What is cmEthernetTrafficPortHistoryATFD?
This counter records the number of tagged frames dropped by this port's Acceptable Frame Policy during the archived historical interval. A historical rise helps the admin date when a port's frame-acceptance policy started rejecting tagged traffic, useful for correlating with a recent VLAN or trunk misconfiguration. For example, if a trunk port was mistakenly reconfigured as access-only last week, the admin would see cmEthernetTrafficPortHistoryATFD begin climbing from that date onward.
