This Recommendation specifies the management information model and data models for Ethernet transport network element (NE) to support specific interface protocols and specific management-control (MC) functions.

The information model is interface protocol neutral and specified using the unified modelling language (UML). The information model of this Recommendation is derived through pruning and refactoring from [ITU-T G.7711] core information model and [ITU-T G.8052] foundation Ethernet transport NE information model.

The data models are interface protocol specific and translated from the information model with the assistance of automated translation tooling. The specific data models considered in this Recommendation include, but are not limited to, YANG data models.

The specific MC functions covered by this Recommendation are the ITU-T defined Ethernet operation, administration, and maintenance (OAM) functions, with the set of op codes assigned to the ITU-T and the corresponding OAM protocol data units (PDU) and behaviours specified in [ITU-T G.8013] and the equipment characteristics in [ITU-T G.8021]. These OAM functions complement the connectivity fault management (CFM) functions currently specified in clause 12.14 of [IEEE 802.1Q]; and the YANG module defined in this Recommendation augments the IEEE 802.1Q CFM YANG module.

Amendment 1 updates the UML model for On-demand measurement and Proactive measurement.
