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 values
of TC0, TC1, TC2, TC3, TC4, TC5,TC6 and TC7 are customized in
qos queue
weight command and their default values are 1, 2, 4, 8, 16, 32, 64 and 127
respectively.
spwrr —— Strict-Pr Weight Round Robin Mode. In this mode, the
switch provides two scheduling groups, SP group and WRR group. SP group
is processed prior to WRR group. Queues in SP group are scheduled strictly
based on Strict-Priority mode while the queues inside WRR group follow the
WRR mode. In SP+WRR mode, TC7 and the queue with its weight value set as
0 are in the SP group; other queues, with none-zero weight value, belong to
the WRR group and the weight value can be customized in
qos queue weight
command. The weight values of TC0, TC1, TC2, TC3, TC4, TC5 and TC6 are 1,
2, 4, 8, 16, 32 and 64 respectively, while the value of TC7 is 0 and
non-configurable.
equ —— Equal-Mode. In this mode, all the queues occupy the bandwidth
equally. The weight value ratio of all the queues is 1:1:1:1:1:1:1:1

Description
The qos queue weight command is used to configure weight value of each
queue after the Schedule Mode is specified as WRR or SP+WRR. The switch
will control the forwarding sequence of the packets according to the priority
