Creating a Maintenance Domain

A Maintenance Domain (MD) is the network or the part of the network for which faults in connectivity are to be managed. A Maintenance Domain consists of a set of Domain Service Access Points.

An MD is fully connected internally. A Domain Service Access Point associated with an MD has connectivity to every other Domain Service Access Point in the MD, in the absence of faults.

Each MD can be separately administered.

The domain-name command in Connectivity Fault Management (CFM) protocol configuration mode creates a maintenance domain with a specified level, name, and ID and enters the specific MD mode specified in the command argument.

device# configure terminal
device(config)# protocol cfm
device(config-cfm)# domain-name md1 id 1 level 4

The no form of the command removes the specified domain from the CFM protocol configuration mode.
