	Table 3-5	Port Spanning Tree Parameters
	Parameter		Description
	STP Mode		The STP administrative mode associated with this port.
			Options: Off, 802.1D, or Fast
			Default: Off
			STP Mode	Description
			Off	Disables STP for this port.
			802.1D	Enables this port to participate in the
				spanning tree and go through all of the
				spanning tree states when the link state
				transitions from down to up.
			Fast	Enables this port to participate in the
				spanning tree and puts it in the forwarding
				state when the link state transitions from
				down to up more quickly than when the
				STP mode is set to 802.1D.
				Note In this state, the forwarding delay
				timer is ignored on link up.
	STP Port Priority		The location of the port in the network topology and how well the port
			is located to pass traffic.
			Range: 0 to 255
			Default: 128
	STP Port Path Cost Mode		Determines whether the STP port path cost is set automatically or
			specified by the user. If you choose User Configured, you also need to
			set a value for the STP Port Path Cost parameter.
			Range: Auto or User Configured
			Default: Auto
	STP Port Path Cost		The speed at which traffic is passed through the port. This parameter
			must be set if the STP Port Path Cost Mode parameter is set to User
			Configured.
			Options: 0 to 65535
			Default: 0, which causes the cost to be adjusted for the speed of the
			port when the link comes up.
			Note Typically, a value of 100 is used for 10-Mbps ports and 19 for
			100-Mbps ports.
