  • Patent number: 11444842
    Abstract: A network switch and a network switch system thereof are provided. The network switch includes a plurality of connection ports and a processing circuit. When any of the connection ports receives a first abnormal message packet and one of the connection ports is in a disabled state, the processing circuit sets the connection port in the disabled state to switch to an enabled state, and the processing circuit does not forward the first abnormal message packet in the single loop network. When one of the connection ports is abnormal and each of the connection ports forming the single loop network is in the enabled state, the processing circuit sets the abnormal connection port to switch to the disabled state, and transmits a second abnormal message packet to other network switches in the single loop network through another connection port that is not abnormal.
