table. If an entry is available for the destination MAC address, the switch forwards the
frame directly from the hardware. If not, it does the following:
Broadcast the frame.
3) After the frame reaches the destination, the destination sends back a response
with its MAC address. (If no response is received, the frame will be dropped.)
4) Upon receipt of the response, the device adds an entry in the MAC address table,
indicating from which port the frames destined for the MAC address should be
sent.
5) Forward subsequent frames destined for the same MAC address directly from the
hardware.
6) Discard the frames which cannot reach the destination MAC address.
