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.
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.
|
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. |
N/A.
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.
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.
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.
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
