queues and scheduling algorithms you set. On this switch, the priority levels are
labeled as TC0, TC1… TC3.
Syntax
qos queue mode { sp | wrr | sp+wrr | equ }
no qos queue mode
Parameter
sp —— 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 —— 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.
sp+wrr —— Strict-Priority + Weight Round Robin Mode. In this mode, the
switch provides two scheduling groups, SP group and WRR group. Queues in
SP group and WRR group are scheduled strictly based on Strict-Priority mode
while the queues inside WRR group follow the WRR mode. In SP + WRR mode,
TC3 is the SP group; TC0, TC1 and TC2 belong to the WRR group and the
weight value ratio of TC0, TC1 and TC2 is 1:2:4. In this way, when scheduling
queues, the switch allows TC3 to occupy the whole bandwidth following the SP
mode and the TC0, TC1 and TC2 in the WRR group will take up the bandwidth
according to their ratio 1:2:4.
equ —— Equal-Mode. In this mode, all the queues occupy the bandwidth
equally. The weight value ratio of all the queues is 1:1:1:1.

Global Configuration Mode
Example
Specify the Schedule Mode as Weight Round Robin Mode:
TL-SL3428(config)#qos queue mode wrr
show qos interface
Description
The show qos interface command is used to display the configuration of QoS
based on port priority.
