Retaining active Operations, Administration, and Maintenance (OAM) sessions across multiple devices operating as a single logical device

A logical Network Interface Device (NID) includes a first NID connected to a peer NID; a second NID connected to the peer NID and communicatively coupled to the first NID, wherein the first NID and the second NID are each connected to a network element for redundant communication to the peer NID, and wherein the first NID actively operates an active maintenance endpoint in an Operations, Administration, and Maintenance (OAM) session with the peer NID, and wherein the active maintenance endpoint synchronizes OAM session data with a dormant maintenance endpoint at the second NID. The dormant maintenance endpoint becomes the active maintenance endpoint responsive to a protection switch, and the dormant maintenance endpoint has the OAM session data in a database based on synchronization with the first NID.
