4. Enter a static list of MEPs assigned to other devices within the same
maintenance association using the mep crosscheck mpid command. This
allows CFM to automatically verify the functionality of these remote end points
by cross-checking the static list configured on this device against information
learned through continuity check messages.
5. Enable CFM globally on the switch with the ethernet cfm enable command.
6. Enable CFM on the local MEPs with the ethernet cfm port-enable command.
7. Enable continuity check operations with the ethernet cfm cc enable command.
8. Enable cross-check operations with the ethernet cfm mep crosscheck
command.
Other configuration changes may be required for your particular environment,
such as adjusting the interval at which continuity check messages are sent
(page 821), or setting the start-up delay for the cross-check operation (page 827).
You can also enable SNMP traps for events discovered by continuity check
messages (page 823) or cross-check messages (page 827).
