parameter to overwrite it. Normally, you are recommended to set the network diameter
to get the other two time parameter of the switch accordingly.
Caution:
In a switching network, you can configure only one root bridge for each STI and one
or more secondary switches. Do not configure more than one root bridge for an STI
at the same time, otherwise, the calculation result will be unpredictable.
After a switch is configured as primary root switch or secondary root switch, user
can't modify the bridge priority of the switch.
Example
# Designate the current switch as the root bridge of STI 1 and specifies the diameter of
the switching network as 4 and the Hello Time as 500 centiseconds.
