Step 13
cfm mep domain domain-name mpid identifier
Example:
Router(config-if-srv)# cfm mep domain MD6 mpid
30
Configure maintenance end points for the domain, and
enter Ethernet cfm mep mode.
• domain domain-name—Specify the name of the
created domain.
• mpid identifier—Enter a maintenance end point
identifier. The identifier must be unique for each
VLAN (service instance). The range is 1 to 8191.
Step 14
end Return to privileged EXEC mode.
Step 15
show ethernet cfm maintenance-points {local |
remote}
Verify the configuration.
Step 16
show ethernet cfm errors [configuration] (Optional) Display the configuration error list.
Step 17
copy running-config startup-config (Optional) Save your entries in the configuration file.
