Configuring the Bridge Spanning Tree Window
The Bridge Spanning Tree window displays STA parameters and allows you to
alter parameters for the 9E312/9E423 Module 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 field displays the “priority” component of the 9E312/9E423 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 range is
0-FFFF hexadecimal; the default value is 8000 hexadecimal.
