This section describes how to switch between connectivity fault management (CFM) versions.
CFM has two versions: IEEE 802.1ag Draft 7 and IEEE Standard 802.1ag-2007. The default CFM version is IEEE Standard 802.1ag-2007.
Perform the following steps on each device on which CFM versions need to be switched:
The system view is displayed.
CFM versions are switched.
Devices running different CFM versions cannot send CFM packets to each other. Therefore, the devices in a maintenance domain (MD) must run the same CFM version.
The configuration is committed.
