It is a proactive OAM functionality is used to detect the state to maintain
connectivity between endpoints. Connectivity failure may be caused by
equipment failure or configuration error.
It is a kind of on-demand OAM functions for the local device and remote
authentication between end devices connected state.
It is a kind of on-demand OAM functions for the local device to determine the

31.2 Configuring CFM
CFM function in the configuration before the network should carry the following plan:
For the maintenance of the entire network to carry out sub-domain level, determine the
level of maintenance of the domain boundary.
Determine the maintenance of the domain name, the same domain on a different device to
maintain the same name.
Required monitoring of VLAN, determine the set of maintenance within the maintenance
domain.
Determine the maintenance set name, the same maintenance domain within the same set
on different devices to maintain the same name.
That the same maintenance domain within the same set of maintenance to maintain a list
of endpoints in the different devices should remain the same.
In the maintenance field and set the boundaries of the maintenance port on the endpoint
should be planned maintenance, non-border or port equipment maintenance can be planned
on a mid-point.
After the completion of network planning, come line the following configuration.
