	Figure 2-26. Bridge STA Information
Parameter	Description
Priority	Device priority is used in selecting the root device, root port, and
	designated port. The device with the highest priority becomes the STA
	root device. However, if all devices have the same priority, the device
	with the lowest MAC address will then become the root device.
Hello Time	The time interval (in seconds) at which the root device transmits a
	configuration message.
Max Age	The maximum time (in seconds) a device can wait without receiving a
	configuration message before attempting to reconfigure.
Forward Delay	The maximum time (in seconds) the root device will wait before
	changing states (i.e., listening to learning to forwarding).
Hold Time	The minimum interval between the transmission of consecutive
	Configuration BPDUs.
Designated Root	The priority and MAC address of the device in the spanning tree that
	this switch has accepted as the root device.
Root Cost	The path cost from the root port on this switch to the root device.
Root Port	The number of the port on this switch that is closest to the root. This
	switch communicates with the root device through this port. If there is
	no root port, then this switch has been accepted as the root device of
	the spanning tree network.
Configuration	The number of times the spanning tree has been reconfigured.
Changes
Topology Up Time	The time since the spanning tree was last reconfigured.
