Basic Configuration Steps for CFM
1. Configure the maintenance domains with the
command.
2. Configure the maintenance associations with the
command.
3. Configure the local maintenance end points (MEPs) which will serve as the domain service
access points for the specified maintenance association using the
command.
4. Enter a static list of MEPs assigned to other devices within the same maintenance association
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
command.
6. Enable CFM on the local MEPs with the
command.
7. Enable continuity check operations with the
command.
8. Enable cross-check operations with the
command.
Other configuration changes may be required for your particular environment, such as adjusting
the interval at which continuity check messages are sent (
), or setting the start-up delay
for the cross-check operation (
). You can also enable SNMP traps for events discovered by
continuity check messages (
) or cross-check messages (
).
