The priority is checked first when two bridges exchange BPDUs. The
bridge with the lower number wins. If the priority is the same then
the bridge's ID is used for the elections.

It would be best to manually set the priority in order to know who
is administratively the active firewall.

facilities. It is just a shell script...
