Connectivity Fault Management
Connectivity Fault Management (CFM) is an OAM protocol that includes proactive
connectivity monitoring using continuity check messages, fault verification
through loop back messages, and fault isolation by examining end-to-end
connections between provider edge devices or between customer edge devices.
CFM is implemented as a service level protocol based on service instances which
encompass only that portion of the metropolitan area network supporting a
specific customer. CFM can also provide controlled management access to a
hierarchy of maintenance domains (such as the customer, service provider, and
equipment operator).
This switch supports functions for defining the CFM structure, including domains,
maintenance associations, and maintenance access points. It also supports fault
detection through continuity check messages for all known maintenance points,
