What is acdCfmMepStatsRxLckPdu?

This counter counts Locked (LCK) PDUs received, which signal that a network segment has been intentionally locked or taken out of service, typically during maintenance. Engineers use lock signals to understand when circuits are being protected or removed from traffic, preventing false alarms during planned work. For example, 2 LCKs received indicates the line was locked twice, perhaps during two separate maintenance windows.
