9.1.4 Schedule Mode

On this page you can select a schedule mode for the switch. 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.

Strict-Priority Mode. In this mode, the queue with higher priority will
occupy the whole bandwidth. Packets in the queue with lower
priority are sent only when the queue with higher priority is empty.
Weight Round Robin Mode. In this mode, packets in all the queues
are sent in order based on the weight value for each queue. The
weight value ratio of TC0, TC1, TC2 and TC3 is 1:2:4:8.
