SET STP

Syntax

set stp [default] [priority=priority] [hellotime=hellotime] [forwarddelay=forwarddelay] [maxage=maxage]

Parameters
default		Disables STP and returns all bridge and port STP
		settings to the default values. This parameter cannot
		be used with any other command parameter and can
		only be used when STP is disabled. (This parameter
		performs the same function as the PURGE STP
		command.)
priority		Specifies the priority number for the bridge. This
		number is used in determining the root bridge for
		STP. The bridge with the lowest priority number is
		selected as the root bridge. If two or more bridges
		have the same priority value, the bridge with the
		numerically lowest MAC address becomes the root
		bridge.
		The range is 0 to 61,440 in increments of 4,096. The
		range is divided into sixteen increments, as shown in
		the following table. You specify the increment that
		represents the desired bridge priority value. The
		default value is 32,768 (increment 8).
