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.   
spwrr  ——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.
