Abstract

Systems and methods of automatically creating and operating a Maintenance End Point (MEP) include, at a slave/reactive network device, receiving an Operations, Administration, and Maintenance (OAM) Protocol Data Unit (PDU) with a destination Media Access Control (MAC) address equal to an interface address of the slave/reactive network device; automatically creating the MEP based on the received OAM PDU and attributes contained in a header of the OAM PDU, wherein the MEP is with a master/active network device; and operating an OAM session with the master/active network device including exchanging Continuity Check Messages (CCMs) with an interval learned from received CCMs from the master/active network device. The systems and methods can further include automatically deleting the MEP responsive to failing to receive any OAM PDUs from the master/active network device during the operating for a predetermined time.
