What is cmEthernetTrafficPortStatsL2CPFD?
This counter tallies Layer 2 Control Protocol frames that were discarded on a cable modem termination system (CMTS) Ethernet port, typically representing frames filtered or dropped for policy or resource reasons. Monitoring this metric helps operators identify whether L2CP filters are functioning correctly. An operator investigating frame loss would examine this counter.
