The application relates to the technical field of industrial automation, and provides a device testing method and system, an electronic device and a computer readable storage medium, the method comprises the following steps: being applied to a device testing system, the device testing system comprises a plurality of devices to be tested, each device to be tested is connected with a physical port of a switch, the switch is connected with a test server, a structured configuration file is analyzed to obtain a device mapping relationship. Based on the device mapping relationship, a plurality of virtual network interfaces are created, and a corresponding network protocol address is allocated to each virtual network interface. An independent routing table is established for each virtual network interface, and a source network protocol address of the virtual network interface is bound to the routing table. Address resolution protocol response control parameters are set for each virtual network interface. A plurality of logically isolated virtual network interfaces can be automatically created, an automatic configuration driven testing environment can be built, and the testing efficiency is improved.

The embodiment of the invention provides an address mapping table updating method, electronic equipment, a storage medium and a program product. The network address change information is actively reported by the terminal equipment or the server-side equipment, and a passive mode of periodic scanning of gateway equipment in the prior art is replaced, so that the updating efficiency and the real-time performance of the address mapping table are remarkably improved; meanwhile, whether the address change information conforms to the network access strategy or not is checked through the preset checking model, updating operation is executed only when the change information passes verification and conforms to the access strategy, illegal and non-compliant address change information can be effectively filtered, network security risks and communication anomalies caused by invalid or illegal updating are avoided, and the user experience is improved. The security and the stability of network operation are improved; in addition, the gateway does not need to execute full-amount periodic scanning, computing resources and network bandwidth occupation of gateway equipment are reduced, and the overall service performance of the gateway is optimized.
