Description: 256 to 511 Octet Frames received in the N2A direction.
What is cmEthernetNetPortStatsESP256?
This counter tracks Ethernet frames received with payloads between 256 and 511 octets traveling in the N2A (network-to-access) direction. Operators use this granular frame-size histogram to understand traffic composition and diagnose potential fragmentation or MTU (Maximum Transmission Unit) issues. It helps characterize the performance and efficiency of Ethernet port utilization.
