• Path Cost (1-200000000) — 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 being rerouted.
• Default Path Cost — Indicates if the device uses the default path cost. The possible field values are:
– Checked — Device uses the default path cost.
– Unchecked — Device uses path cost defined in the Path Cost field above.
• 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 provided in
increments of 16.
• Designated Bridge ID — The bridge priority and the MAC Address of the designated bridge.
• Designated Port ID — The designated port's priority and interface.
