Port Spanning Tree Parameters Screen
Use the Port Spanning Tree Parameters screen to set up STP priorities for each port.
Port
The number of the port.
Priority
Priority associated with the port. The port with the lowest priority value has the
highest priority and will forward the spanning tree frames. The default is 128. The
possible range is 0 through 255 (decimal). If all ports have the same priority value,
the lowest port number forwards the spanning tree frames.
Path Cost
Cost associated with the port. The spanning tree protocol uses port path costs to
determine which port to select as a forwarding port. Therefore, lower numbers
should be assigned to ports attached to faster media (such as FDX or CrossLink),
and higher numbers should be assigned to ports attached to slower media. The
possible range is 1 to 65,535. The default is 62. The recommended path cost is
