What is acdCfmMepStatsRxLbrUnexpectedPdu?

This counter tracks Loopback Replies that arrive when no loopback test was initiated, indicating unsolicited or ghost packets on the link. Engineers monitor this to detect stray responses, misconfigured loops, or replay attacks on the network. For example, a value of 1 means 1 loopback reply came back without sending a matching request.
