    AoA. Sorry I could not clear Idea of Flooded and Broadcast frame. Switch first time do flood when any port transmit frame. After MAC Table when switch transmit data to all ports except originate port, It is called broadcast. Is it right ?




    Flooding is the process you described by which a switch learns a remote host MAC address.

    When a switch receives a Broadcast (BC) Frame with a Destination IP address: (FFFF.FFFF.FFFF.FFFF) from an Address Resolution Protocol (ARP) request from Host 1 with a value of all 255s. The switch floods this frame out all other ports of the switch except the port where the frame was received and waits for a unicast reply from the remote Host 2 that matches the Destination IP before updating its MAC Address table.

    Let me know if this helps clarify your issue.




    Thanks for helping out! I really appreciate it.
