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.
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.
The priority and MAC address of the device through which this
port must communicate to reach the root of the spanning tree.
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.
