Description
The rules defining po rt status are:
• A port on a networ k segment with no other STA
compliant bridging device is always fo rwarding.
• 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 fo rwards
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 number of times the port has changed status to
for warding state.
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 pr iority and number of the po rt on the d esignated
bridging device through which this switch must
communicate with the root of the spanning tree.
