Ethernet Oam; Connectivity Fault Management - Cisco ASR 903 Manual

Ethernet over MPLS

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.
