What is adnAeiPortErrNCRCCounter?

This counter measures cyclic redundancy check (CRC) errors detected on ATM cells arriving from the network side, indicating data corruption during transmission. Network engineers monitor this to identify physical link quality problems or noise affecting incoming traffic. If this counter is high (e.g., 10,000+), it signals potential cable damage, interference, or a flaky network connection requiring investigation.

Examples
