Ethernet OAM
CFM, 802.3ah(ethernet in the first mile), Ethernet Local Management Interface (LMI) are supported on the
ASR903.
Connectivity Fault Management
Ethernet connectivity fault management (CFM) is an end-to-end per-service-instance Ethernet layer OAM protocol
that includes proactive connectivity monitoring, fault verification, and fault isolation.
