23.4.5 Configuring MSTP Bridge Priority
In MSTP, the bridge priority is based on the parameters of MSTI, the bridge priority
together with port priority and port path cost determines the topology of each spanning tree
instance, constitute the basis for link load balancing.
Switch bridge priority determines the size of this switch is able to be selected as the
spanning tree root bridge. By configuring the bridge priority of the smaller, you can specify a
switch to become the spanning tree root bridge purposes.
By default, the switch bridge priority is 32768.

23.4.6 Configuring Port Boundary Port Status
Border and port means connected to the host ports that can linkup within a very short time
after entering the forwarding state, but once these ports receive spanning tree packets will
automatically switch to non-border ports.
