maintenance level number range is 0 to 7.
Step 4 service {ma-name | ma-number | vpn-id vpn} {vlan
vlan-id}
Define a customer service maintenance association name
or number or VPN ID to be associated with the domain, and
a VLAN ID, and enter ethernet-cfm-service configuration
mode.
•ma-name—a string of no more than 100 characters that

cannot use the same VLAN ID for more than one
domain at the same level.
Step 5 mep mpid identifier Define the MEP maintenance end point identifier in the
domain and service. The range is 1 to 8191
Step 6 end Return to privileged EXEC mode.
Step 7 ethernet cfm mep crosscheck {enable | disable}
