摘要： A control device, an execution device, a device management method, and a device management system are provided, and are applied to the field of network technologies. The control device includes: a network communications interface, configured to connect to an execution device through a network, where the execution device is a network communications device; and a processor, configured to send a device management protocol packet through the network communications interface, where the device management protocol packet indicates an operation performed on a register in a first chip in the execution device and/or the device management protocol packet indicates that a pin of a second chip in the execution device is set to a status indicated by the device management protocol packet. In this application, the control device is responsible for controlling a part such as a bus or a chip of the execution device or a pin of the chip. Therefore, when the execution device is updated, only the control device needs to be upgraded, thereby reducing maintenance costs.
