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.

20. See

"Configuring Maintenance End Points"
