Description: Packet Discarded due to Lookup Fail.
What is cmEthernetTrafficPortHistoryLkupFails?
This counter records the number of packets discarded on this Ethernet port during the archived historical interval because a forwarding-table lookup failed. A historical rise in lookup failures points the admin toward a forwarding-table capacity or a MAC/route-table population problem that was affecting this port during that period. For example, if a switch's MAC table filled up last week causing intermittent drops, the admin would confirm the timing by checking when cmEthernetTrafficPortHistoryLkupFails on affected ports began rising.
