SET STP PORT

Syntax

set stp port=port [pathcostportcost=autoportcost] [portpriority=portpriority]

Parameters
port	Specifies the port you want to configure. You can
	configure more than one port at a time. You can
	specify the ports individually (for example, 5, 7, 22), as
	a range (for example, 18-23), or both (for example, 1, 5,
	14-22).
pathcost	Specifies the port’s cost. The parameters are
portcost	equivalent. The spanning tree algorithm uses the cost
	parameter to decide which port provides the lowest
	cost to the root bridge for that LAN. This parameter
	can take the range of 1 to 65,535, or AUTO. The default
	setting is AUTO, for Automatic Update, which
	automatically sets port cost according to the speed of
	the port. Table 2 lists the STP port costs with Auto-
	Detect.
