Spanning Tree Information
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.

|
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. |

Last Topology | The time since the spanning tree was last reconfigured. |
