Purpose
Define a CFM domain, set the domain level, and enter
ethernet-cfm configuration mode for the domain. The
maintenance level number range is 0 to 7.
(Optional) Assign a maintenance domain identifier.
• mac-address domain_number—Enter the MAC
address and a domain number. The number can be from
0 to 65535.
dns name—Enter a DNS name string. The name can be
•
a maximum of 43 characters.
null—Assign no domain name.
•
Define a customer service maintenance association (MA)
name or number or VPN ID to be associated with the
domain, a VLAN ID or port MEP, and enter
ethernet-cfm-service configuration mode.
ma-name—a string of no more than 100 characters that
•
identifies the MAID.
ma-number—a value from 0 to 65535.
•
vpn-id vpn—enter a VPN ID as the ma-name.
•
vlan vlan-id—VLAN range is from 1 to 4094. You
•
cannot use the same VLAN ID for more than one
domain at the same level.
• (Optional) direction down—specify the service
direction as down.
• port—Configure port MEP, a down MEP that is
untagged and not associated with a VLAN.
Enable sending and receiving of continuity check
messages.
(Optional) Set the interval at which continuity check
messages are sent. The available values are 100 ms,
1 second, 10 seconds, 1 minute and 10 minutes. The default
is 10 seconds.
Because faster CCM rates are more CPU-intensive,
Note
we do not recommend configuring a large number
of MEPs running at 100 ms intervals.
(Optional) Set the number of continuity check messages to
be missed before declaring that an MEP is down. The range
is 2 to 255; the default is 3.
(Optional) Configure the maximum number of MEPs
allowed across the network. The range is from 1 to 65535.
The default is 100.
