queue0-weight
queue6-weight queue7-weight: Customizes the weights to be assigned to queues 0 through 7. The
value ranges from 0 to 15 in both system view and Ethernet port view. A value of 0 means the
corresponding queue adopts the SP algorithm for queue scheduling.
Description
Use the queue-scheduler command to configure the queue scheduling algorithm and the related
parameters.
Use the undo queue-scheduler command to restore the default.
By default, the WRR algorithm is used for all the output queues of a port. The default weights of queues
0 through 7 are 1, 2, 3, 4, 5, 9, 13, and 15, as shown in

A port of an S3600 Ethernet switch supports eight output queues, to which these queue scheduling
algorithms are applicable: SP, WRR, and WFQ. With WRR (or WFQ) adopted, if you set the weight or
the bandwidth of one or multiple queues to 0, the device will add the queue or these queues to the SP
group, where SP is adopted. For other queues, WRR (or WFQ) still applies. In this case, both SP and
WRR (or WFQ) are adopted.
Note that:
The queue scheduling algorithm specified by executing the queue-scheduler command in system
view takes effect on all the ports. The queue scheduling algorithm configured in port view must be
the same as that configured in system view. Otherwise, the system will prompt configuration errors.
For example, if you configure queues 0 and 2 to adopt SP and queues 3 through 7 to adopt WRR in
system view, you can modify the weights of queues 3 through 7 in port view but cannot modify the
queue scheduling algorithm of any queue in port view.
If the weight (or bandwidth value) specified in system view for a queue of WRR queuing or WFQ
queuing cannot meet the requirement of a port, you can modify the weight (or bandwidth value) for
this port in the corresponding Ethernet port view. The new weight (or bandwidth value) takes effect
only on the port while the weights on the other ports remain as set in system view.
If the weight (or bandwidth value) specified in system view for a queue of SP-WRR queuing or
SP-WFQ queuing in the command cannot meet the requirement of a port, you can modify the
weight (or bandwidth value) for this port in the corresponding Ethernet port view. The new weight
(or bandwidth value) takes effect only on the port.
