Description:
Layer 2 Control Protocol Frames Discarded in the N2A direction.
What is cmEthernetNetPortStatsL2CPFD?
This counter counts Layer 2 Control Protocol (L2CP) frames that were discarded in the N2A (Network-to-Access) direction on an Ethernet port during a performance monitoring interval. L2CP frames carry control information for protocols like Spanning Tree; discarding them indicates filtering or congestion. Operators monitor this to ensure critical protocol frames are not being dropped and to identify port congestion issues.
