What is cmEthernetNetPortHistoryESF?
This counter tracks the number of fragmented Ethernet frames detected on a network port in the Network-to-Access (N2A) direction during a specific historical interval. Fragment detection indicates that the ingress traffic experienced frames that were broken into smaller pieces, usually due to interface errors or MTU mismatches. An operator would check this metric to diagnose packet fragmentation problems and assess network port health over time.
