SMC Networks 1000BASE-X manual Address table is cleared, and the port begins

USING THE SYSTEM CONFIGURATION PROGRAM

Parameter	Description
Type	Shows port type as:
	100FX	: 100BASE-FX
	1000SX	: 1000BASE-SX
	1000LX	: 1000BASE-LX
	1000T	: 1000BASE-T
Status	Displays current state of this port within the Spanning Tree:
	No Link	No link has been established on this port.
	Disabled	Port has been disabled by the user or has failed
		diagnostics.
	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	Port 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	The cost for a packet to travel from this port to the root in the
Cost	current Spanning Tree configuration. The slower the media, the
	higher the cost.
