1. method that is used to detect the loop between the network equipment comprises:

  • Determine media interviews control (MAC) mobile threshold value;

    The mobile number of times of MAC Address between the port of the network equipment counted to obtain MAC move counting;

    Determine whether MAC Address has moved to the port of before finding described MAC Address at its place;

    If described MAC Address has moved to the port of before finding described MAC Address at its place, then MAC is moved counting and be weighted;

    MAC is moved counting to be moved threshold value and compares with MAC;

    AndExceed MAC and move threshold value if MAC moves counting, conclude that then loop exists.
