begins to process user frames and start updating the MAC address table. But the user
frames are not forwarded to the destination. After a forward time delay (The default
forward delay time is 15 seconds), the switch port moves from the learning state to the
forwarding state.
Forwarding : A port in the forwarding state forwards frames across the attached
network segment. In a forwarding state, the port will process BPDUs, update its MAC
Address table with frames that it receives, and forward user traffic through the port.
Forwarding State is the normal state. Data and configuration messages are passed
through the port, when it is in forwarding state.
Broken : If the bridge has detected a port that is malfunctioning it will place that port into
the broken state.
