configure cfm domain association add

configure cfm domain domain_name association association_name [ports port_list add [[end-point [up|down] mepid { group group_name } ] | [intermediate-point]]

Description

This command allows you to create an up MEP, down MEP, intermediate-point (MIP) on a maintenance association, a group. You can also combine different maintenance points.

Combining different Maintenance points is restricted per the following:

Up MEP and Down MEP in a single association is not allowed.
Down MEP and MIP in a single association is not allowed.
More than one Up MEP in a single association is not allowed.
Up MEP and MIP in a single association is allowed.
More than one Down MEP in a single association is allowed.
A group can be created while creating a MEP.
With CFM Support over VPLS, this command is used to associate pseudo wires of a VPLS service instance to an association & domain.
Portlist can have only one port configured for a MEP configuration but can have multiple ports in MIP configuration, when Hwaoam is supported on the system.

Syntax Description

domain_name	Enter the domain associated with the MA you are configuring.
association_name	IEEE 802.1ag or ITU-T Y.1731 association name.
port_list	Specifies the port number(s).
up	Enter the port to be the UP port of the MA; this MEP sends CCM messages to all ports—other than the sending switch port—in this MA on this switch.
down	Enter the port to be the DOWN port of the MA; this MEP sends CCM messages out of the configured physical port.
mepid	Specifies a value for this MEP. The range is 1 to 8191. NOTE: On each MA, each MEPID must be unique.
group	CFM group that binds an LMEP to RMEPS. If not specified, the client does not receive events from the respective RMEPs.
group_name	Group name, maximum of 31 characters.

Default

N/A.

Usage Guidelines

These ports must already be in the MA (VLAN (Virtual LAN) 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.

Note

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.

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

You can also combine different maintenance points. The following are CLI restrictions on MP combinations:

DOWN and UP MEP cannot be present on the same association
DOWN MEP and MIP cannot be present on the same association
UP MEP and MIP can be present on the same association
Only one UP MEP is allowed in an association
Multiple DOWN MEPs are allowed in an association

You can configure a total of 32 MIPs on a single switch.

Use the show cfm command to verify your configuration.

Example

The following command configures port 1:20 as a MIP on the 350 association in the spain domain:

configure cfm domain spain association 350 ports 1:20 add intermediate-point

The following command configures port 5:10 to be the UP MEP on the test association in the brazil domain, with a mepid of 500:

configure cfm domain brazil association test ports 5:10 add end-point up 500

History

This command was first available in ExtremeXOS 11.4.

This command was updated in ExtremeXOS 15.2 to include the optional group parameter.
