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…TC6.

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.
WRR-Mode:
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 to TC6 is
