By default, the queue
scheduling algorithm
adopted on all the ports is
WRR. The default
weights of the eight output
queues of a port are 1, 2,
3, 4, 5, 9, 13, and 15 (in
the order queue 0 through
queue 7).

By default, the queue
scheduling algorithm
adopted on all the ports is
WRR. The default weights
of the eight output queues
of a port are 1, 2, 3, 4, 5,
9, 13, and 15 (in the order
queue 0 through queue
7).
A port of an S5600 Ethernet switch supports eight output queues. SP and WRR queue
scheduling algorithms are available. With WRR adopted, if you set the weight of one or
multiple queues to 0, the switch will add the queue or these queues to the SP group,
where SP is adopted. For other queues, WRR still applies. In this case, both SP and
WRR are adopted.
In cases where both SP and WRR queue scheduling algorithms are adopted, the
queues in the SP group take precedence over other queues. For example, if queue 0,
queue 1, queue 2, and queue 3 are in the SP group, queue 4, queue 5, queue 6, and
queue 7 are scheduled using WRR, the switch will schedule the queues in the SP group
preferentially by using the SP algorithm. Then queues outside the SP group are
scheduled by using the WRR algorithm only when all the queues in the SP group are
empty.
