A Maintenance Endpoint (MEP) represents a managed CFM entity, associated with a specific Domain Service Access Point (DoSAP) of a service instance, which can generate and receive CFM Protocol Data Units (PDU) and track any responses. A MEP is created by MEP ID under the context of an MA. MEP functionality can be divided into the following functions:
Fault Detection
Fault Verification
Fault Isolation
Fault Notification
Fault detection and notification are achieved through the use of Continuity Check Messages (CCM). CCM messages are not supported.
