Bridge Priority / Root Priority
Which device becomes the root bridge is decided based on the bridge priority. The bridge
with the highest priority (in other words, with the lowest value for this parameter) becomes
the root bridge. If several devices in a network have the same priority, the device whose
MAC address has the lowest numeric value will become the root bridge. Both
parameters, bridge priority and MAC address together form the bridge identifier. Since
the root bridge manages all path changes, it should be located as centrally as possible
due to the delay of the frames. The value for the bridge priority is a whole multiple of
4096 with a range of values from 0 to 32768.
●
Bridge Addresse / Root Addresse
The bridge address shows the MAC address of the device and the root address shows
the MAC address of the root bridge.
●
The path costs from this device to the root bridge.
