What is cmEthernetNetPortHistoryESC?
This object counts Ethernet collision events detected on a network port in the N2A (Network-to-Access) traffic direction during a historical measurement interval. In half-duplex Ethernet, collisions occur when two devices transmit simultaneously on the same physical medium, indicating contention or misconfiguration. An operator monitors this metric to diagnose physical layer problems or verify proper half/full-duplex mode negotiation.
