Configuring the Bridge Spanning Tree Window

The Bridge Spanning Tree window displays STA parameters and allows you to alter parameters for the device 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.

Bridge Level Fields

Bridge Priority

This Þeld displays the ÒpriorityÓ component of the deviceÕs unique bridge identiÞer. The Spanning Tree Algorithm assigns each bridge a unique identiÞer, which is derived from the bridgeÕs MAC address and the Priority. The bridge with the lowest value of bridge identiÞer is selected as the Root. A lower priority number indicates a higher priority; a higher priority enhances a bridgeÕs chance of being selected as the Root.

You can edit this text box to change network topology, if needed. The default value is 8000; the range is 0ÑFFFF hexadecimal.
