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.

Abstract translation: 本发明的实施例公开了一种用于升级网络设备和设备的版本的方法。 具体的解决办法是将网络设备的转发平面配置为第一个转发平面和第二个转发平面; 在第一转发平面中，通过使用预设采样比对转发的分组进行采样，以获得采样分组; 通过第二转发平面以广播方式转发该采样包，以学习MAC地址; 当第二转发平台学到的MAC地址量达到预设阈值时，执行升级，使第二转发平面用于网络设备的分组转发。 该技术解决方案可以有效避免在版本升级过程中产生大量广播报文，有助于减少过度占用的网络带宽，避免网络拥塞。
