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.
