Configuring Interfaces
for CFM
CFM processes are enabled by default for all physical interfaces, both ports and
trunks. You can use the Administration > CFM (Configure Interface) page to change
these settings.
Command Usage
â—† An interface must be enabled before a MEP can be created (see "Configuring
Maintenance End Points").
â—† If a MEP has been configured on an interface, it must first be deleted before
CFM can be disabled on that interface.
â—† When CFM is disabled, hardware resources previously used for CFM processing
on that interface are released, and all CFM frames entering that interface are
forwarded as normal data traffic.
Web Interface
To enable CFM on an interface:
1. Click Administration, CFM.
2. Select Configure Interface from the Step list.
3. Select Port or Trunk.
4. Enable CFM on the required interface.
5. Click Apply.

Maintenance Domains
Use the Administration > CFM (Configure MD) pages to create and configure a
Maintenance Domain (MD) which defines a portion of the network for which
connectivity faults can be managed. Domain access points are set up on the
boundary of a domain to provide end-to-end connectivity fault detection, analysis,
and recovery. Domains can be configured in a hierarchy to provide management
access to the same basic network resources for different user levels.
