Adds local ports as Maintenance End Points (MEPs) to a specific Maintenance Association (MA).
There are no MEP configured.
CFM protocol configuration mode
The no mep command deletes the MEP from the MA.
A Maintenance Domain (MD) is part of a network controlled by one operator. The MD levels are carried on all CFM frames to identify different domains. Every MD can be divided into smaller networks having multiple MEPs. Usually an MA is associated with a service instances (for example a VLAN or a VPLS).
VPLS is not supported on devices based on the XGS chipset family. For a list of such devices, see "Supported Hardware".
MEP is located on the edge of an MA. It defines the endpoint of the MA. Each MEP has unique ID (MEPID) within MA. The connectivity in a MA is defined as connectivity between MEPs. The MEP generates Continuity Check Message and multicasts to all the other MEPs in the same MA to verify connectivity.
Each MEP has a direction, down or up. Down MEP receives CFM PDUs from the LAN and sends CFM PDUs towards the LAN. Up MEP receives CFM PDUs from a bridge relay entity and sends CFM PDUs towards the bridge relay entity on a bridge. End stations support down MEPs only because they have no bridge relay entities.
This example defines a MEP for VLAN 30 in the down direction.
