Parameter	Description

Type	Shows port type as 1000SX (1000BASE-SX).
Status	Displays the current state of this port within the spanning tree:
	Disabled	Port has been disabled by the user or has failed diagnostics.
	No Link	There is no valid link on the port.
	Blocking	Port receives STA configuration messages, but does not forward
		packets.
	Listening	Port will leave blocking state due to topology change, starts
		transmitting configuration messages, but does not yet forward packets.
	Learning	Has transmitted configuration messages for an interval set by the
		Forward Delay parameter without receiving contradictory information.
		Port address table is cleared, and the port begins learning addresses.
	Forwarding	The port forwards packets, and continues learning addresses.

The rules defining port status are:

•A port on a network segment with no other STA-compliant bridging device is always forwarding.

•If two ports of a switch are connected to the same segment and there is no other STA device attached to this segment, the port with the smaller ID forwards packets and the other is blocked.

•All ports are blocked when the switch is booted, then some of them change state to listening, to learning, and then to forwarding.

Designated Cost	The cost for a packet to travel from this port to the root in the current spanning tree
	configuration. The slower the media, the higher the cost.
Designated	The priority and MAC address of the device through which this port must
Bridge (ID)	communicate to reach the root of the spanning tree.
Designated Port	The priority and number of the port on the designated bridging device through which
(ID)	this switch must communicate with the root of the spanning tree.
