Spanning Tree Protocol - Port
Cost
Type the port's cost.
STP uses the available port with the lowest cost to forward
frames to the root port. All other ports are blocked.
It is recommended to set a lower value for faster links.
This field only appears if the selected bridge uses STP. It is
relevant for regular bridged connections only.
Spanning Tree Protocol - Port
Priority
Select the port's priority.
The port's priority is combined with the port's logical number to
create the port's ID. The port with the lowest ID is elected as
the root port, which forwards frames out of the bridge. The
other ports in the bridge calculate the least-cost path to the
root port, in order to eliminate loops in the topology and
provide fault tolerance.
To increase the chance of this port being elected as the root
port, select a lower priority.
Note:
If you select the same priority for all ports, the root port
will be elected based on the port's logical number.
The default value is 128.
This field only appears if the selected bridge uses STP. It is
relevant for regular bridged connections only.
