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.
