Configuring the Maintenance End Point Direction

You can specify the direction in which CFM packets are transmitted for the MEP.

Direction up CCMs are transmitted out of every logical interface which is part of the same bridging or VPLS instance except for the interface configured on this MEP.

Direction down CCMs are transmitted only out of the interface configured on this MEP.

Note: Ports in the STP blocking state do not block CFM packets destined to a down MEP. Ports in STP blocking state without the continuity check protocol configured, do block CFM packets.

To configure the direction, include the direction statement at the [edit protocols oam ethernet connectivity-fault-management maintenance-domain domain-name maintenance-association ma-name mep mep-id] hierarchy level.
