Web Interface
To configure global settings for CFM:
1. Click Administration, CFM.
2. Select Configure Global from the Step list.
3. Before enabling CFM processing on the switch, first configure the required CFM
domains, maintenance associations, and static MEPs. Then set the delay time to
wait for a remote MEP comes up before the switch starts cross-checking the
end points learned through CCMs against those stored in the static list.
4. Adjust the parameters for the link trace cache as required.
5. Enable the required traps for continuity check and cross-check errors.
Remember that the “Connectivity Check” and “Cross Check” fields on the MA
Configuration page must be enabled before related errors can be generated.
6. Click Apply.
