Spanning Tree 2-35

Bridging
Figure 2-10. 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 values displayed apply to the currently-selected bridging interface,
highlighted in the lower right quadrant of the window. To view or alter the
parameters of another interface, click on the appropriate Port X name listed in the
quadrant.
Bridge Level
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.
