	DESCRIPTION
		"The administrative value of the Edge Port parameter.  A
		value of true(1) indicates that this port should be

		that this port should be assumed as a non-edge-port.





		Setting this object will also cause the corresponding
		instance of dot1dStpPortOperEdgePort to change to the

		is true, the value of the corresponding instance of
		dot1dStpPortOperEdgePort can be false if a BPDU has

	DESCRIPTION
		"The administrative point-to-point status of the LAN segment
		attached to this port, using the enumeration values of the
		IEEE 802.1w clause.  A value of forceTrue(0) indicates
		that this port should always be treated as if it is
		connected to a point-to-point link.  A value of
		forceFalse(1) indicates that this port should be treated as
		having a shared media connection.  A value of auto(2)
		indicates that this port is considered to have a
		point-to-point link if it is an Aggregator and all of its





		members are aggregatable, or if the MAC entity
		is configured for full duplex operation, either through
		auto-negotiation or by management means.  Manipulating this
		object changes the underlying adminPortToPortMAC.

		The value of this object MUST be retained across
		reinitializations of the management system."

	MAX-ACCESS read-only
	STATUS  current
	DESCRIPTION
		"The operational point-to-point status of the LAN segment
		attached to this port.  It indicates whether a port is
		considered to have a point-to-point connection.
		If adminPointToPointMAC is set to auto(2), then the value
		of operPointToPointMAC is determined in accordance with the
		specific procedures defined for the MAC entity concerned,
		as defined in IEEE 802.1w, clause 6.5.  The value is
		determined dynamically; that is, it is re-evaluated whenever
		the value of adminPointToPointMAC changes, and whenever
		the specific procedures defined for the MAC entity evaluate
		a change in its point-to-point status."

	MAX-ACCESS read-write
	STATUS  current
	DESCRIPTION
		"The administratively assigned value for the contribution
		of this port to the path cost of paths toward the spanning
		tree root.

		Writing a value of '0' assigns the automatically calculated
		default Path Cost value to the port.  If the default Path
		Cost is being used, this object returns '0' when read.

		This complements the object dot1dStpPortPathCost or
		dot1dStpPortPathCost32, which returns the operational value
		of the path cost.

		reinitializations of the management system."
