When the network is congested, the problem that many packets compete for resources must be solved, usually in the way of queue scheduling. The switch will control the forwarding sequence of the packets according to the priority queues and scheduling algorithms you set. On this switch, the priority levels are labeled as TC0, TC1... TC3. Choose the menu QoS→DiffServ→Schedule Mode to load the following page. Figure 9-7 Schedule Mode The following entries are displayed on this screen:  Schedule Mode Config SP-Mode: Strict-Priority Mode.
