configure cfm domain association end-point transmit-interval

configure cfm domain domain_name association association_name {ports port_list end-point [up | down]} transmit-interval [3|10|100|1000|10000|60000|600000]


Allows you to change time interval for an MEP to send out a CCM. We recommend configuring this value as at least 1 second.

Syntax Description


Enter the domain associated with the MA you are configuring.


IEEE 802.1ag or ITU-T Y.1731 association name.


Enter the port number of the MEP on which you are changing the time interval it sends out a CCM.


Enter this variable if you are changing the time interval for sending a CCM on an UP MEP.


Enter this variable if you are changing the time interval for sending a CCM on a DOWN MEP.


1000 ms.

Usage Guidelines

Use this command to change the time interval between sending out CCMs on a previously configured UP or DOWN MEP. If you attempt to change the interval on a port that is either not an MEP or having wrong MEP type, the system returns an error message.



We recommend that you use a transmit interval of at least 1 second (1000 ms).

The receiving system also uses this value multiplied by 3.5 to determine when the MEP is no longer alive.

Use the show cfm command to verify your configuration and the show cfm detail command to display the configured lifetime.



The transmit interval value “3” is 3.3 msec. Also, the values 60000 and 600000 are supported in hardware.


The following command changes the interval the UP MEP (previously configured on port 2:4) uses to send CCM messages on the 350 association in the finance domain to 10 seconds:

configure cfm domain finance association 350 ports 2:4 end-point up transmit-interval 10000
