Recommendation ITU-T G.8052/Y.1346 contains the protocol neutral UML information model for Ethernet transport network (NE) management. The model is based on the Ethernet equipment functions specified in Recommendation ITU-T G.8021/Y.1341, generic management requirements in Recommendation ITU-T G.7710/Y.1701, and Ethernet specific management requirements in Recommendation ITU T G.8051/Y.1345. The 2016 revision of this Recommendation changes the UML modelling tool from RSA to open source Papyrus tool, updates the Recommendation ITU-T G.8052/Y.1346 information model to align it with the Recommendation ITU-T G.7711/Y.1702 v2.0 Core information model, drops subclassing of the TP classes from Recommendation ITU-T M.3160, and supports the additional management requirements in Recommendation ITU-T G.8051/Y.1345. The 2018 revision of this Recommendation up-versions the UML model tool to Papyrus v3.2.0 and the profile to v0.2.13, deletes ODUkP-X-L (from the CsfRdiFdiEnableSink_Pac, CsfRdiFdiEnableSource_Pac, and CsfReportSink_Pac), replace ETY termination points with ETHnull termination points, removes ODUkp/ETH_A and ODU2P/ETHPP-OS_A, adds Annex A for the Ethernet Spec model.
