• 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 re-
routed.
• 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 -240.
The priority value is determined in increments of 16.
• Designated Bridge ID — Indicates the bridge priority and the MAC Address of the
designated bridge.
• Designated Port ID — Indicates the selected port priority and interface.
• 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
Discarding state to Forwarding state.
