P OINTS
Use the Administration > CFM (Configure MEP – Add) page to configure
Maintenance End Points (MEPs). MEPs, also called Domain Service Access
Points (DSAPs), must be configured at the domain boundary to provide
management access for each maintenance association.
CLI R EFERENCES
◆ "CFM Commands" on page 1309
C OMMAND U SAGE
◆ CFM elements must be configured in the following order: (1)
maintenance domain at the same level as the MEP to be configured
(see "Configuring CFM Maintenance Domains" ), (2) maintenance
association within the domain (see "Configuring CFM Maintenance
Associations" ), and (3) finally the MEPs using the MEP List.
◆ An interface may belong to more than one domain, or to different MAs
in different domains.
◆ To change the MEP’s MA or the direction it faces, first delete the MEP,
and then create a new one.
P ARAMETERS
These parameters are displayed:
◆ MD Index – Domain index. (Range: 1-65535)
◆ MA Index – MA identifier. (Range: 0-4094)
◆ MEP ID – Maintenance end point identifier. (Range: 1-8191)
◆ MEP Direction – Up indicates that the MEP faces inward toward the
switch cross-connect matrix, and transmits CFM messages towards,
and receives them from, the direction of the internal bridge relay
mechanism. If the Up option is not selected, then the MEP is facing
away from the switch, and transmits CFM messages towards, and
receives them from, the direction of the physical medium.
◆ Interface – Indicates a port or trunk.

2. Select Configure MEP from the Step list.
3. Select Add from the Action list.
4. Select an entry from MD Index and MA Index.
