This specifies the MEP ID (constrained to the valid 1-8191 range) that a frame-loss measurement message (LMM) test targets, mirroring the delay-test target field but for loss measurement, identifying exactly which remote peer this particular loss test is being run against. An admin sets this to direct a loss measurement at one specific remote peer on a multipoint service, rather than measuring loss in aggregate across every remote MEP at once. For example, cienaCesCfmFrameLossMsgTargetMEPID set to 30 would run the loss measurement specifically against the remote peer identified by MEP ID 30, isolating that one peer's loss performance from any others on the same service.
