The classification is based on the queue. Generally, you need to create a root category for a queue, and then create a subcategory on it. For a classification, the classification takes effect in the order of serial numbers, and smaller serial numbers take precedence. Once a data packet is sent through a classification matching rule, the subsequent classification does not take effect. 1) create a root category:, assign a bandwidth of 10 Mbit, and set the priority to 8. · TC class add Dev
