This TruthValue controls whether automatic remote MEP aging is enabled for the service, meaning whether remote MEPs that stop being heard from are automatically aged out of the service's known-remote-MEP list after some period, rather than being remembered indefinitely. An admin disables this on services where the exact, fixed set of remote MEPs is manually provisioned and should never be silently forgotten just because of a temporary outage, while leaving it enabled on more dynamic, multipoint services where remote endpoints legitimately come and go. For example, disabling cienaCesCfmServiceRMEPAging on a critical point-to-point EVC ensures the far-end MEP entry (and its historical stats) stays in the table through a brief outage rather than disappearing and having to be rediscovered.
