(Optional) Switching CFM Versions

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:

Run system-view
The system view is displayed.
Run cfm version { draft7 | standard }
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.
Run commit
The configuration is committed.
