CFM Commands
Basic Configuration Steps for CFM
1. Configure the maintenance domains with the ethernet cfm domain command.
2. Configure the maintenance associations with the ma index name 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 ethernet cfm mep
command.
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 (see
“ethernet cfm cc ma interval” on
page 537), or setting the start-up delay for the cross-check operation (see “ethernet cfm mep
crosscheck start-delay” on page 542). You can also enable SNMP traps for events discovered by
continuity check messages (see “snmp-server enable traps ethernet cfm cc” on page 539) or
cross-check messages (see “snmp-server enable traps ethernet cfm crosscheck” on page 543).
