What is adnAeiPortErNCRCCounter?
This counter tracks cyclic redundancy check (CRC) errors detected on cells coming from the network side of the port, indicating data corruption in transit. Network engineers use this to assess link quality and identify when physical repairs or link re-negotiation is needed. A counter jumping from 50 to 500 in an hour signals a serious line quality degradation requiring immediate action.
