What is acdCfmMepStatsRxVsmPdu?

This counter tallies Vendor Specific Message (VSM) PDUs received, which are proprietary diagnostic or maintenance packets unique to a particular equipment vendor. Engineers running multi-vendor networks monitor VSM counts to understand when vendor-specific operations are being used, which may not be portable. For example, 30 VSMs received indicates the endpoint performed 30 vendor-specific diagnostic or operational procedures.
