Abstract: Embodiments of the present invention disclose a method for upgrading a version of a network device and a device. A specific solution is: configuring a forwarding plane of the network device to be a first forwarding plane and a second forwarding plane; performing, in the first forwarding plane, sampling on forwarded packets by using a preset sampling ratio, to obtain a sample packet; forwarding, by the second forwarding plane, the sample packet in a broadcast manner, to learn a MAC address; and when a quantity of MAC addresses learned by the second forwarding plane reaches a preset threshold, performing upgrade so that the second forwarding plane is used for packet forwarding of the network device. The technical solution can effectively avoid generation of a large quantity of broadcast packets during a version upgrade process, can help reduce network bandwidth that is excessively occupied, and avoid network congestion.
