DES-3326S Layer 3 Fast Ethernet Switch User’s Guide

Bridge Identifier		A combination of the User-				32768 + MAC
		set priority and the switch’s
(Not	user-	MAC address.		The	Bridge
configurable		Identifier	consists		of two
except by setting		parts: a 16-bit priority and
priority below)		a 48-bit Ethernet MAC
		address
Priority		A relative priority for each				32768
		switch – lower numbers give
		a higher priority and a
		greater chance of a given
		switch being elected as the
		root bridge
Hello Time		The length of time between				2 seconds
		broadcasts	of	the	hello
		message by the switch
Maximum	Age	Measures the age of a				20 seconds
Timer		received BPDU for a port
		and ensures that the BPDU
		is discarded when its age
		exceeds the value of the
		maximum age timer.
Forward	Delay	The amount time spent by a				15 seconds
Timer		port in the learning and
		listening states waiting for a
		BPDU that may return the
		port to the blocking state.
