¿µ¹®³»¿ë¿ä¾à This standard provides the motivations and requirements for user-plane operation, administration, and maintenance(OAM) functionality for ETH layer in Ethernet-based networks and Ethernet services.
This standard specifies mechanisms required to operate and maintain the network and service aspects of ETH layer. It also specifies the Ethernet OAM frame formats and syntax and semantics of OAM frame fields. The OAM mechanisms as described in this standard apply to both point-to-point ETH connections and multipoint ETH connectivity. The OAM mechanisms as described in this standard are applicable to any environment independently of how the ETH layer is managed.
This standard includes the requirements for OAM functions for the point-to-point and multipoint-to-multipoint maintenance entities(MEs) including both dedicated and shared access. It is noted that this standard does not address the administration aspects of OAM.
