• Blocking: The port is currently blocked and cannot be used to forward

traffic or learn MAC addresses.

• Listening: The port is currently in the listening mode. The port cannot

forward traffic nor can it learn MAC addresses.

• Learning: The port is currently in the learning mode. The port cannot

forward traffic, however, it can learn new MAC addresses.

Port Role Each MST Bridge Port that is enabled is assigned a Port Role for each

spanning tree. The port role will be one of the following values: Root Port,

Designated Port, Alternate Port, Backup Port, Master Port, or Disabled

Port.

Designated Root Root Bridge for the selected MST instance. It is made up using the bridge

priority and the base MAC address of the bridge.

Designated Cost Displays cost of the port participating in the STP topology. Ports with a lower

cost are less likely to be blocked if STP detects loops.

Designated Bridge Bridge Identifier of the bridge with the Designated Port. It is made up using

the bridge priority and the base MAC address of the bridge.

Designated Port Port Identifier on the Designated Bridge that offers the lowest cost to the

LAN. It is made up from the port priority and the interface number of the port.
