Defining STP on Interfaces
•Speed — Indicates the speed at which the port is operating.
•Path Cost — Indicates the port contribution to the root path cost. The path cost is adjusted to a higher or lower value, and is used to forward traffic when a path is
•Priority — Priority value of the port. The priority value influences the port choice when a bridge has two ports connected in a loop. The priority value is between 0
•Designated Bridge ID — Indicates the bridge priority and the MAC Address of the designated bridge.
•Designated Port ID — Indicates the selected port
•Designated Cost — Indicates the cost of the port participating in the STP topology. Ports with a lower cost are less likely to be blocked if STP detects loops.
•Forward Transitions — Indicates the number of times the port has changed from Forwarding state to Block- ing state.
•LAG — Indicates the LAG to which the port belongs.
