Connectivity Fault Management (CFM) over EVC BD

Connectivity Fault Management (CFM) over EVC BD
IEEE CFM is an end-to-end per-service Ethernet-layer Operations, Administration, and Maintenance
(OAM) protocol. CFM includes proactive connectivity monitoring, fault verification, and fault isolation
for large Ethernet metropolitan-area networks (MANs) and WANs.
CFM over EVC BD (Up mep) and CFM over EVC BD (Down mep) features are supported on CFM over
EVC BD.
CFM over Xconnect (Up mep) and CFM over Xconnect (Down mep) features are not supported on CFM
over EVC BD.
The benefits of Ethernet CFM are:
This feature is supported only if you have purchased the appxk9 licensing package. CFM over EVC BD
