Configuration Guide for H3C S 12500 Series Routing Switches -R 1828P04-6W 182. This manual belongs to H3C, not Huawei. However, Huawei and Huawei have the same basic commands in equipment configuration. And what you need to know is that the equipment of different manufacturers is different, and the equipment of the same manufacturer will have different models, so the command in many cases in the actual scene is different. Doesn't mean you can learn everything from a manufacturer's equipment instructions. The key point is to learn a technology and its principle. This configuration guide gives the concept, principle, usage scenarios, cases and configuration commands and descriptions corresponding to the cases. Knowing this manual, you can have a basic understanding of most technologies.
