QoS queue settings configuration parameters
The following section describes the parameters for configuration of the QoS queue settings located

Queues 0, 1, and 2 are configured as strict priority queues. The weights for these queues default to
0 and cannot be changed. The weights of the remaining queues (queues 3 to 7) can be any value
within the range except 0. The remaining queues are configured as weighted round robin (WRR).
Packets received in strict priority queues receive immediate service from the scheduler, thereby
pre-empting scheduling for WRR queues.
