This Recommendation specifies the requirements and analysis for the management interface between the Element Management System (EMS) and the Network Management System (NMS) of Metro Ethernet as defined in MEF-10 and Ethernet over Transport (EoT), specifically the Ethernet ETH layer as defined in [ITU-T G.8010]. This Recommendation follows the interface specification methodology described in [ITU-T M.3020]. In this Recommendation, the EMS is an Operations System (OS) used to manage the individual network elements supporting Metro Ethernet and EoT services as well as the networks between them. One or more EMSs may be deployed depending on the different supplier products and geographic distribution of the network elements in the network. The NMS represents an integrated management OS across different technologies and EMSs. The NMS communicates with EMS through the Q Interface to realize its management functions. The management functions covered in this Recommendation include configuration management, performance measurement parameters management, and alarm reporting and testing in fault management. These management functions are described and divided by UML use cases in the requirements. The analysis provides the managed entities which support a protocol-neutral information model for Metro Ethernet and EoT management, and also explains the static and dynamic relationships between these managed entities using UML class diagrams and sequence diagrams. This Recommendation does not cover all aspects about Ethernet management; only those related to Metro Ethernet and EoT services management are addressed. This Recommendation is built on and extends the information model provided in [MEF 7].
