What is cmEthernetAccPortStatsESUP?
This counter tracks the number of undersized (runt) Ethernet frames received on an access port in the access-to-network (A2N) direction, which are typically indicative of transmission errors, collisions, or misconfigured equipment. High counts suggest link quality problems or incompatible connected devices. Network engineers monitor this metric to identify physical layer issues and validate cable and transceiver health.
