Cost

the link speed has been auto negotiated.

The state field shows the current state of the port. The state field can be either

 

BLOCKING, LISTENING, LEARNING, FORWARDING, or DISABLED.

Bridge

each port, if applicable. Information includes the priority (hex) and MAC

 

address of the Designated Bridge.
