This Recommendation defines the service attributes and parameters for carrying Ethernet characteristic information over shared-bandwidth, multipoint-to-multipoint connections, provided by SDH, ATM, MPLS, PDH, ETY, OTH or ETH server layer networks. This type of service is referred to as Ethernet virtual private LAN service. This Recommendation is based on the Ethernet service framework as defined in [ITU-T G.8011].

This Recommendation specifies three attributes sets (EVC, UNI and NNI) and values to describe an Ethernet virtual private LAN service from the perspective of the network.
