What is acdCfmMepStatsRxLtrUnexpectedPdu?

This counter tracks Link Trace Reply (LTR) packets that arrive when no trace request was actually sent, indicating unsolicited or stray network traffic. Engineers monitor this to detect configuration mismatches, rogue devices, or packets echoing back from unexpected sources. For example, a value of 2 means 2 trace replies arrived without a corresponding request, which may warrant investigation.
