About Ethernet CFM
Ethernet CFM is an end-to-end per-service-instance (per-VLAN) Ethernet layer OAM protocol. It
includes proactive connectivity monitoring, fault verification, and fault isolation. End-to-end can be
provider-edge-to provider-edge (PE-to-PE) device or customer-edge-to-customer-edge (CE-to-CE)
device. Ethernet CFM, as specified by IEEE 802.1ag, is the standard for Layer 2 ping, Layer 2 traceroute,
and end-to-end connectivity verification of the Ethernet network.
