IEEE 802.1ag and ITU-T Y.1731 OAM protocols on up MEPs

IEEE 802.1ag configuration fault management (CFM) and ITU-T Y.1731 performance-monitoring OAM protocols on up maintenance association end points (MEPs). CFM OAM protocol is supported on link aggregation group (LAG) or aggregated Ethernet (AE) interfaces. The ITU-T Y.1731 protocol supports delay measurement on up MEPs but does not support loss measurement on up MEPs.
