1. A method for forming a correct forwarding table through CPU periodic broadcast or multicast is characterized by comprising the following steps:

  • (1) closing the unidirectional broadcast from the MAC unit to the CPU unit in a register of the MAC unit, and keeping the unidirectional broadcast from the CPU unit to the MAC unit;

    (2) the CPU unit generates and sends a broadcast packet or a multicast packet at intervals, and the broadcast packet or the multicast packet can be flooded;

    (3) the MAC unit, switch and all PC units form the correct form to the CPU unit;

    (4) when the management PC unit sends web unicast data to the CPU unit, a forwarding table to the PC unit is formed through the switch and the MAC unit;

    (5) when web unicast data reaches a CPU unit, a mac-ip corresponding table of the CPU unit is formed by a source mac and a source ip.
