Method and system for detecting status of network equipment in real time

The invention discloses a method and system for detecting the status of network equipment in real time. The method mainly comprises the following steps that: a work station transmits a data frame to the network equipment; the network equipment receives the data frame, records the source of the data frame, and transmits the data frame to the work station after the status of the network equipment changes; and the work station detects the running state information of the network equipment in real time through the data frame transmitted by the network equipment. In the invention, the work station can receive the data frame from the network equipment in real time so as to know the running status of the network equipment. When a communication fault occurs, the problem of the work station or the fault of the network equipment can be known immediately, so that an error is found quickly and the fault is cleared.
