This specifies the MEP ID (constrained to the valid 1-8191 range defined by 802.1ag) that a delay-measurement message (DMM) test targets, identifying exactly which remote peer this particular delay/jitter measurement is being run against. An admin sets this to point a delay test at a specific remote endpoint when a maintenance association has multiple remote MEPs and only one particular peer's delay characteristics need to be measured. For example, cienaCesCfmDelayMsgTargetMEPID set to 25 on a multipoint service would run the delay measurement specifically against the remote peer using MEP ID 25, leaving any other remote MEPs on the same service untested by this particular DMM session.
