Creating a MEP

Creating a MEP


MEPs define a CFM area. CFM supports continuity check (CC), loopback (LB), and linktrace (LT) functions on end-to-end links between MEPs.

MEPs are classified into the local MEP and RMEPs.

MEPs are classified into inward- and outward-facing MEPs based on the MEP direction. Device interfaces at both ends of the direct link must be Layer 2 interfaces and support direct link and end-to-end link.

Perform the following operations on each edge device in an MA.


  1. Run system-view

    The system view is displayed.

  2. Run cfm md md-name

    The MD view is displayed.

  3. Run ma ma-name

    The MA view is displayed.

  4. Run mep mep-id mep-id interface interface-type interface-number [ pe-vid pe-vid ce-vid ce-vid ] { outward | inward }

    The MEP is created.

Follow-up Procedure

  • To create multiple MEPs in an MA, repeat step 4.

  • To create MEPs in multiple MAs, repeat steps 3 and 4.

Do not configure level-0 MEPs on intermediate devices. To specify the level of a MEP, run the cfm md md-name [ level level ].
