Configuring the Bridge Spanning Tree Window

The Bridge Spanning Tree window displays STA parameters and allows you to alter parameters for the selected bridge as a whole, and for each individual bridging interface.

The currently selected bridging interface is highlighted in the lower right quadrant of the window. To alter the parameters of another interface, click on the appropriate Port X name listed in the quadrant.

The Bridge Spanning Tree window provides the following bridge-level information:

Bridge Priority

This field displays the “priority” component of the module’s unique bridge identifier. The Spanning Tree Algorithm assigns each bridge a unique identifier, which is derived from the bridge’s MAC address and the Priority. The bridge with the lowest value of bridge identifier is selected as the Root. A lower priority number indicates a higher priority; a higher priority enhances a bridge’s chance of being selected as the Root.

You can edit this text box to change network topology, if needed. The default value is 8000.
