configure cfm domain association ports end-point ccm

configure cfm domain domain_name association association_name ports port_list end-point [up | down ] ccm [disable | enable]


This command is used to enable or disable sending CCMs on a given MEP.

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 you want to configure as either an UP or DOWN MEP.



Usage Guidelines

Each MA needs at least two MEPs that can reach each other to exchange CCM messages.



Ensure that you assigned the port number correctly to the UP MEP and to the DOWN MEP, or the CCM messages go in the wrong direction.

These ports must already be in the MA (VLAN or VMAN) prior to assigning a MEP function to them. If you try to assign a port not in the MA as an end-point, the system returns the following message:

The following port(s) <portlist> are not part of the associations VLAN.

Use the show cfm command to verify your configuration.


configure cfm domain "MD1" association "MD1v1" ports 17 end-point down delete group "eapsCfmGrp"
