Ports

The parameters shown in the following figure and table are for port STA Information (Port 1-8).

Figure 3-14. STA Information - Ports

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. 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.
Forward Transitions	The number of times the port has changed status to forwarding
	state.
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.
