Recommendation ITU-T G.8151/Y.1374 addresses management aspects of the MPLS transport profile (MPLS-TP) capable network element containing transport functions of one or more of the layer networks of the MPLS-TP network. The management of the MPLS-TP layer networks is separable from that of its client layer networks so that the same means of management can be used regardless of the client. The management functions for fault management, configuration management, performance monitoring, and security management are specified.

The 2012 revision of this Recommendation aligns with the MPLS-TP architecture and requirements jointly developed by IETF and ITU-T, and provides the specification for managing MPLS-TP network elements (NEs) that support the OAM protocol neutral equipment functionality as defined in Recommendation ITU-T G.8121/Y.1381.
