•
Path Cost—Set the port contribution to the root path cost or use the default
cost generated by the system.
•
Priority—Set the priority value of the port. The priority value influences the
port choice when a bridge has two ports connected in a loop. The priority is
a value from 0 to 240, set in increments of 16.
•
Port State—Displays the current STP state of a port.
-
Disabled—STP is currently disabled on the port. The port forwards
traffic while learning MAC addresses.
-
Blocking—The port is currently blocked, and cannot forward traffic (with
the exception of BPDU data) or learn MAC addresses.
-
Listening—The port is in Listening mode. The port cannot forward traffic,
and cannot learn MAC addresses.
-
Learning—The port is in Learning mode. The port cannot forward traffic,
but it can learn new MAC addresses.

•
Designated Cost—Displays the cost of the port participating in the STP
topology. Ports with a lower cost are less likely to be blocked if STP detects
