Step 3
ethernet cfm traceroute cache [size entries |
hold-time minutes]
(Optional) Configure the CFM traceroute cache. You can
set a maximum cache size or hold time.
• (Optional) For size, enter the cache size in number of
entry lines. The range is from 1 to 4095; the default is
100 lines.
• (Optional) For hold-time, enter the maximum cache
hold time in minutes. The range is from 1 to 65535; the
default is 100 minutes.
Step 4
ethernet cfm mip auto-create level level-id vlan
vlan-id
(Optional) Configure the router to automatically create
MIPs for VLAN IDS that are not associated with specific
maintenance associations at the specified level. The level
range is 0 to 7.
Note Configure MIP auto-creation only for VLANs that
MIPs should monitor. Configuring for all VLANs
can be CPU and memory-intensive.
Step 5
ethernet cfm mip filter (Optional) Enable MIP filtering, which means that all CFM
frames at a lower level are dropped. The default is disabled.
Step 6
ethernet cfm domain domain-name level level-id 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.
Step 7
id {mac-address domain_number | dns name | null} (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.
Step 8
service {ma-name | ma-number | vpn-id vpn} {vlan
vlan-id [direction down] | port}
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.
Step 9
continuity-check Enable sending and receiving of continuity check
messages.
