The Spanning Tree Information screen displays a summary of the STA information for the overall bridge or for a specific port. To make any changes to the parameters for the Spanning Tree, use the STA Configuration and STA Port Configuration screens.

Spanning Tree

The parameters shown in the following figure and table describe the current bridge STA Information.

Figure 3-13. STA Information - Spanning Tree
Parameter	Description
Spanning Tree	Shows if the switch is enabled to participate in an STA-
State	compliant network.
Bridge ID	A unique identifier for this bridge, consisting of bridge priority
	plus MAC address (where the address is normally taken from
	Port 1).
Max Age	The maximum time (in seconds) a device can wait without
	receiving a configuration message before attempting to
	reconfigure.
Hello Time	The time interval (in seconds) at which the root device transmits
	a configuration message.
Forward Delay	The maximum time (in seconds) the root device will wait before
	changing states (i.e., listening to learning to forwarding).
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.
Designated Root	The priority and MAC address of the device in the spanning tree
	that this switch has accepted as the root device.
Root Path Cost	The path cost from the root port on this switch to the root device.
Configuration	The number of times the spanning tree has been reconfigured.
Changes
Last Topology	The time since the spanning tree was last reconfigured.
