2.6.5 STP Settings Configuration

STP is disabled by default. The table below lists the default STP settings when the STP is enabled.

Table 2-4 Default STP Values

	Setting	Default Value	Range		Purpose
	Bridge priority	32768	0-65535	A parameter used to identify the
					root bridge in a spanning tree
					(instance of STP). The bridge
					with the lowest value has the
					highest priority and is the root
	Bridge max age	20	6-40	The interval a bridge will wait for
					a hello packet from the root
					bridge before initiating a topology
					change
	Bridge hello time	2	1-10	The interval of time between
					each configuration BPDU sent by
					the root bridge.
	Bridge forward delay	15	4-30	The period of time a bridge will
					wait (the listen and learn period)
					before beginning to forward data
					packets.
	Ethernet port (ETH A)	100	0-65535	The cost of using the port to
	path cost				reach the root bridge. When
					selecting among multiple links to
					the root bridge, STP chooses the
					link with the lowest path cost and
					blocks the other paths. Each port
					type has its own default STP path
					cost.
	Ethernet port (ETH A)	128	0-255	The preference that STP gives to
	priority				this port relative to the other ports
					for forwarding traffic out of the
					spanning tree.
					A higher numerical value means
					a lower priority; thus, the highest
					priority is 8.
	Ethernet port (ETH B)	100	0-65535	The cost of using the port to
	path cost				reach the root bridge. When
					selecting among multiple links to
					the root bridge, STP chooses the
					link with the lowest path cost and
					blocks the other paths. Each port
					type has its own default STP path
					cost.
	Ethernet port (ETH B)	128	0-255	The preference that STP gives to
