switch is the Designated Bridge.

modified according to the STA specification.
User-Changeable Parameters
The factory default setting should cover the majority of
installations. However, it is advisable to keep the default settings

♦ Bridge Priority A Bridge Priority can be from 0 to 65535.
0 is equal to the highest Bridge Priority.
♦ Bridge Hello Time The Hello Time can be from 1 to 10
seconds. This is the interval between two transmissions of
BPDU packets sent by the Root Bridge to tell all other
