Displaying Global Settings for STA
Use the Spanning Tree > STA (Configure Global - Show Information) page to display
a summary of the current bridge STA information that applies to the entire switch.
Parameters
The parameters displayed are described in the preceding section, except for the
following items:
◆ Bridge ID – A unique identifier for this bridge, consisting of the bridge priority,
the MST Instance ID 0 for the Common Spanning Tree when spanning tree type
is set to MSTP, and MAC address (where the address is taken from the switch
system).
◆ Designated Root – The priority and MAC address of the device in the Spanning
Tree that this switch has accepted as 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.
◆ Root Path Cost – The path cost from the root port on this switch to the root
device.
◆ Configuration Changes – The number of times the Spanning Tree has been
reconfigured.
◆ Last Topology Change – Time since the Spanning Tree was last reconfigured.
Web Interface
To display global STA settings:
1. Click Spanning Tree, STA.
2. Select Configure Global from the Step list.
3. Select Show Information from the Action list.
