This object specifies the direction, inward or outward facing on the bridge port, in which all Maintenance association End Points within this Maintenance Association face, as part of Ethernet CFM fault management configuration. An administrator sets this when defining a CFM maintenance association to control whether fault-detection monitoring points watch traffic heading into the bridge or out toward the wire. Choosing an outward-facing direction would position the MPs to monitor the link segment beyond that port rather than internal switch traffic.
