Command Manual – QoS
H3C S7500E Series Ethernet Switches
Description
Use the qos wrr command to configure Weighted Round Robin (WRR) queue
scheduling algorithm or the SP + WRR queue scheduling algorithm on a port or port
group.
Use the undo qos wrr command to restore the default queue-scheduling algorithm on
the port.
By default, the switch adopts the SP queue-scheduling algorithm.
As required, you can configure part of the queues on the port to adopt the SP
queue-scheduling algorithm and parts of queues to adopt the WRR queue-scheduling
algorithm. Through adding the queues on a port to the SP scheduling group and WRR
scheduling group (namely, group 1), the SP + WRR queue scheduling is implemented.
During the queue scheduling process, the queues in the SP scheduling group is
scheduled preferentially. When no packet is to be sent in the queues in the SP
scheduling group, the queues in the WRR scheduling group are scheduled. The
queues in the SP scheduling group are scheduled according to the strict priority of each
queue, while the queues in the WRR queue scheduling group are scheduled according
the weight value of each queue.

Examples
# Configure SP+WRR queue scheduling algorithm on Ethernet 2/0/1 as follows: assign
queue 0, queue 1, queue 2, and queue 3 to the SP scheduling group; and assign queue
4, queue 5, queue 5, and queue 7 to WRR scheduling group, with the weight 2, 4, 6,
and 8.
