Anti-interference method and system for Ethernet equipment

The invention relates to the technical field of Ethernet communication, in particular to an anti-interference method and system for Ethernet equipment, and the method comprises the steps: obtaining an interface signal of a medium-related interface of the Ethernet equipment, and judging whether the interface signal is saturated or not; if yes, setting a protection state for the Ethernet equipment, and continuously acquiring an interface signal until the medium-related interface exits the overshoot state; judging whether the signal quality on the medium related interface is reduced or not; and if yes, updating the filter coefficient of the adaptive filter. The method has the beneficial effects that the interface signal is detected in the communication process of the Ethernet equipment, and when the interface signal is overshot, the Ethernet equipment is switched into a protection state to avoid equipment disconnection, so that a relatively stable communication effect is realized. Furthermore, after the overshoo
