WEB-BASED MANAGEMENT

Parameter	Description
	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 status to
Transitions	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.
Designated Bridge	The priority and MAC address of the device through which
	this port must 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 this switch must communicate
	with the root of the spanning tree.
