A read-write setting selecting the device-wide queue scheduling algorithm: strict priority (sp), weighted round robin (wrr), a combination of both (spWrr), or weighted fair prioritization (wfp). This determines how the device's output queues are serviced relative to each other; strict priority always drains higher queues first while WRR shares bandwidth proportionally by weight, which directly affects how traffic in different queues competes for available bandwidth during congestion. The MIB's own example shows this object read back as wrr(2), meaning the device is using weighted round robin scheduling with the per-queue weights defined in deviceBaseQosPolicyWeightOctet.
