stack-port qos queue
Function
The stack-port qos queue command configures the WRR or WDRR weight for queues on an interface of the stack.
The undo stack-port qos queue command restores the default WRR or WDRR weight for queues on a stack interface.
By default, the WRR or WDRR weight for queues on an interface of the stack is 1.
Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S5735-L, S5735S-L, S5735S-L-M, S5735-S, S5735S-S, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support this command.
Format
stack-port qos queue queue-index { wrr | drr } weight weight
undo stack-port qos queue queue-index { wrr | drr } [ weight weight ]
The WRR weight of queues cannot be set on the stack interface of the S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S.

Usage Guidelines
Usage Scenario
When using WRR or WDRR scheduling, you can set the weight for each queue. Then the switch schedules queues in turn based on the weights. If the weight of a queue is set to 0, the queue uses PQ scheduling. In this case, PQ+WRR or PQ+WDRR is used.
Prerequisites
The stack-port qos { pq | wrr | drr } command has been executed to configure the WRR or WDRR scheduling mode of queues on a stack interface.
