Parameter	Description
Port Status	Displays the current state of this port within the spanning
	tree:
	No Link	There is no valid link on the port.
	Disabled	Port has been disabled by the user or has failed
		diagnostics.
	Blocked	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.
		Portaddresstable is cleared, andtheportbegins
		learning addresses.
	ForwardingThe 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.
Forward	The number of times the port has changed to a forwarding
Transitions	state.
Designated	The cost for a packet to travel from this port to the root in
Cost	the current spanning tree configuration. The slower the
	media, the higher the cost.
Designated	The priority and MAC address of the device through which
Bridge	this port must communicate to reach the root of the
	spanning tree.
