Patent number: 11956114Abstract: A device management method includes a first network device sending a first remote procedure call (RPC) request message to a second network device, where the first RPC request message includes information about a third yet another next generation (YANG) module that is identifiable to the first network device. After the second network device switches to the third YANG module, the first network device establishes a control session between the first network device and the second network device based on the third YANG module. When the network device supports switching between YANG modules of different standards, the second network device is notified, by using an RPC, to switch to a YANG module supported by the first network device.Type: GrantFiled: March 25, 2022Date of Patent: April 9, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Xinning Dai, Rui Chen, Chuxi Li, Qin Wu
