CFM Support on Routed Port and Port MEP
IEEE Connectivity Fault Management (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.
Note
This feature is supported only if you have purchased the DATA technology package functionality
(
datak9
) licensing package. For more information about managing software activation licenses on the
Cisco ISR and Cisco ISR G2 platforms, see

Restrictions for Configuring Ethernet CFM
•
A specific domain must be configured. If it is not, an error message is displayed.
•
Multiple domains (different domain names) having the same maintenance level can be configured.
However, associating a single domain name with multiple maintenance levels is not permitted.
