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 1000 / LAN speed in Mbps.

STP Mode
The port’s spanning tree mode. Possible values are forwarding, blocked, and auto.
When auto is selected, the spanning tree protocol will be used to determine the forwarding/blocking state.
When set to blocked, the port will not forward any frames. When set to forwarding, the port will always forward frames.
On SmartStack
If the port is used to connect to a single station, forwarding might be the preferred mode since it might take 30 seconds or more before a port is opened until it starts forwarding frames. If connected to a shared media or a bridge, be careful not to create loops.
