What is nncAAL5InvalidFormatPDU?
This counter gives the total number of AAL5 invalid format PDU errors seen on the interface. It flags PDUs that failed to conform to the expected AAL5 trailer or length format, which usually indicates a malformed sender or a corrupted transmission. An admin troubleshooting an ATM circuit that drops connections intermittently would watch this counter for spikes correlated with the outages.
