♦ State Indicates the current state of the port. A port can have the
following states: Disabled, Blocking, Listening, Learning,
Forwarding, and Broken. A broken state means that the link on the
port has been broken because the port is malfunctioning. Blocking
means that the port has been blocked because it is neither a root port
nor a designated port. In STP, only root and designated ports are
used.
♦ Designated Root Indicates the MAC (Ethernet) address of the
switch/bridge that is the STP designated root for the network.
♦ Designated Cost Displays the path cost from this port to the
designated root.
