3. Bridges elect the device with the lowest bridge ID (priority plus MAC
address) root. You can manipulate which device becomes root by chang-
ing devices' priorities. Enter a number between 0 and 65535 in the Bridge
Priority field. For example, enter 0 to ensure that the local router
becomes root. In Figure 14-83, the priority has been set to 0 to ensure that
it becomes the root. (The default priority is 32768.)
You should alter timers only if you have a great deal of experience working
with spanning tree protocols. Otherwise, you could slow convergence or
cause interfaces to toggle between forwarding and blocked states.
4. Enter times for the forward delay, hello, and maximum age timers in the
corresponding fields. Click Apply.
The Restore Factory Defaults button returns the timers and STP version
to their defaults. The Reset button returns to the settings that were
established the last time you clicked Apply.
