Designated Cost

The cost of the path from this port to the Root Bridge on the network. If the highlighted port is the Root Port, the Designated Cost is 0. If this bridge is the Root Bridge, all its bridge ports have a Designated Cost of 0. This value is compared to the Root Path Cost field in received configuration BPDUs.

Designated Root

The unique Bridge Identifier of the bridge that is assumed to be the Root Bridge on the network; this information is contained in the Configuration BPDUs.

Designated Bridge

Displays the MAC address and priority component of the Bridge ID for the bridge that is believed to be the Designated Bridge for the network segment associated with this port.

The Designated Bridge ID, along with the Designated Port and Port Identifier parameters for the port, is used to determine whether this port should be the Designated Port for the network segment to which it is attached.
