Ethernet OAM Overview
Prime Network Vision supports three, interrelated OAM components, including:
• Connectivity Fault Management—Connectivity Fault Management (CFM) is an end-to-en d
per-service-instance (per VLAN) Ethernet layer OAM protocol that includes connectivity
monitoring, fault verification, and fault isolation. CFM allows you to manage in dividual c usto me r
service instances. Ethernet Virtual Connections (EVCs) are the services that are sold to customers
and are designated by service VLAN tags. CFM operates on a p er-service -VL AN (or per-EVC)
basis. It lets you know when an EVC fails and provides tools to isolate the failure. See Viewing
Connectivity Fault Management Properties, page 15-3 and Configuring CFM, page 15-18.
