Ports

The parameters shown in the following figure and table are for port STA

Information.

Parameter Description

Port Status Displays the current state of this port within the spanning tree:

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.

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 port on the designated bridging device through which this switch must

communicate with the root of the spanning tree.
