4.5 Configuring SP+WRR Queues
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.
4.5.1 Configuration Procedure
