3Com Switch 4800G 24-Port - Configuring SP+WRR Queues

Configuring SP+WRR Queues 881
Configuration Examples Network requirements
Configure WRR queue scheduling algorithm on GigabitEthernet1/0/1, and assign
weight 1, 2, 4, 6, 8, 10, 12, and 14 to queue 0 through queue 7.
Configuration procedure
# Enter system view.
<Sysname> system-view
# Configure the WRR queues on GigabitEthernet1/0/1 port.

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.

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.
