2. Change minimum percentage of a port outbound bandwidth guaranteed to the queues.
device(config)# qos guaranteed-rate qosp0 10 qosp1 10 qosp2 15 qosp3 15 qosp4 10 qosp5 10 qosp6 10
qosp7 10
3. Change the name of QoS queue 3.
device(config)# qos name qosp3 r3d3
The default queue names are qosp7, qosp6, qosp5, qosp4, qosp3, qosp2, qosp1, and qosp0. You can change one or more of
the names if desired.
4. Return to privileged EXEC mode.
device(config)# exit
5. Verify the configuration
device# show qos guaranteed-rate
Profile qosp7 : Minimum Guaranteed bandwidth 10
Profile qosp6 : Minimum Guaranteed bandwidth 10
Profile qosp5 : Minimum Guaranteed bandwidth 10
Profile qosp4 : Minimum Guaranteed bandwidth 10
Profile r3d3 : Minimum Guaranteed bandwidth 15
Profile qosp2 : Minimum Guaranteed bandwidth 15
Profile qosp1 : Minimum Guaranteed bandwidth 10
Profile qosp0 : Minimum Guaranteed bandwidth 10
6. Save the configuration.

Changing the minimum bandwidth percentages of the WRR queues
If you are using the weighted round robin mechanism instead of the strict priority mechanism, you can change the weights for each queue
by changing the minimum percentage of bandwidth you want each queue to guarantee for its traffic.
By default, the eight QoS queues on Ruckus FastIron devices receive the minimum guaranteed percentages of a port’s total bandwidth, as
shown in the following table. Note that the defaults differ when jumbo frames are enabled.
