Description: 256 to 511 Octet Frames received in the N2A direction.
What is cmEthernetNetPortHistoryESP256?
This counter records the total number of Ethernet frames between 256 and 511 octets in size that were received on this port in the N2A (direction toward the N-side) during a performance history interval. Tracking frame size distribution helps diagnose network performance issues and understand application behavior. Network operators use this data to identify unusual traffic patterns, detect fragmentation issues, or verify that quality-of-service policies are correctly processing different frame sizes.
