Forwarding tab
The Forwarding tab displays the current state of the port, as defined by application
of the Spanning Tree Protocol. This state controls what action a port takes on
reception of a frame. If the bridge detects a port that is malfunctioning, it places
the port into the “broken” state. For ports that are disabled, the value is “disabled.”
