What is cmEthernetTrafficPortStatsLkupFails?
This counter tracks the number of packets discarded because they failed forwarding table lookups on an Ethernet interface, indicating packets with unknown or unreachable destinations. A high count suggests routing table problems, topology changes, or misconfigured networks. Operations teams monitor this metric to detect forwarding failures and diagnose reachability issues.
