Ethernet OAM Overview
Ethernet OAM Overview
Prime Network Vision supports three, interrelated OAM components, including:
• Connectivity Fault Management—Connectivity Fault Management (CFM) is an end-to-end
per-service-instance (per VLAN) Ethernet layer OAM protocol that includes connectivity
monitoring, fault verification, and fault isolation. CFM allows you to manage individual customer
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 per-service-VLAN (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.
