This Counter32 reports the total number of MEPs (Maintenance Entity Group End Points, both local and remote combined per its plain reading) configured under this CFM service, giving a quick census figure for how many monitoring endpoints exist on this maintenance association. An admin compares this figure against the expected topology (e.g. a point-to-point EVC should show exactly 2 MEPs) to catch a missing or an unexpectedly extra MEP without walking the entire MEP table row by row. For example, cienaCesCfmServiceNumMEP reading 3 on a service that should be a simple two-ended point-to-point circuit would immediately flag an unexpected third MEP that needs investigating.
