By default, all the ports adopt the WRR queue scheduling algorithm, with the weight values assigned to
queue 0 through queue 7 being 1, 2, 3, 4, 5, 9, 13, and 15.
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 GigabitEthernet 1/0/1 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.
