QoS Scheduler Operation
In stacking mode, the QoS scheduler operation is different for the stacking ports and the data ports.
The scheduler for the data ports operates the same as for standalone ExtremeSwitching switches and is managed with the following command:
configure qosscheduler [default |strict-priority | weighted-round-robin | weighteddeficit- round-robin]
The scheduler for the stacking ports is defined by the software when the stack is configured, and it cannot be modified. For all switches, the scheduler is set to strict-priority for the stacking ports, and meters are used to elevate the queue 6 priority above the priority of the other queues. This is the only scheduling method for stack ports.
