Chapter 10 Configuring Ethernet OAM
Step 5
continuity-check
Example:
Router(config-ecfm-srv)# continuity-check
Enable sending and receiving of continuity check
messages.
Step 6
continuity-check interval value
Example:
Router(config-ecfm-srv)# continuity-check
interval 1s
(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.
Note Because faster CCM rates are more CPU-intensive,
we do not recommend configuring a large number
of MEPs running at 100 ms intervals.
Step 7
continuity-check loss-threshold threshold-value
Example:
Router(config-ecfm-srv)# continuity-check
loss-threshold 4
(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.
Step 8
alias{alias-short-ma-name | icc icc-code meg-id |
number ma-number | vlan-id vlan-id | vpn-id vpn-id}
Example:
Router(config-ecfm-srv)# alias MA6
Define a customer alias 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.
• alias-short-ma-name—a string of no more than 100
characters that identifies the MAID.
• icc icc-code meg-id—specify the ITU Carrier Code
(ICC) (maximum: 6 characters) and Unique
Maintenance Entity Group (MEG) ID Code (UMC).
The maximum characters allowed is 12.
• number ma-number—a value from 0 to 65535.
• vlan-id 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.
• vpn-id vpn-id—enter a VPN ID as the ma-name.
Step 9
exit Return to ethernet-CFM configuration mode.
Step 10
exit Return to global configuration mode.
Step 11
interface interface-id
Example:
Router(config)# interface gigabitethernet 0/4
Specify an interface to configure, and enter interface
configuration mode.
Step 12
service instance number ethernet name
Example:
Router(config-if)# service instance 30 ethernet
EVC30
Specify the service instance number and the name of the
EVC.
