The qos low-latency enable command enables the low-latency function.
The undo qos low-latency enable command disables the low-latency function.
By default, the low-latency function is not enabled.
Usage Scenario
To enable the low-latency function for flow queues in PQ scheduling mode, run the qos flow-queue low-latency enable command. After the low-latency function is globally disabled, the low-latency function that is enabled for a specified queue by running the queue command in the flow-queue profile is still effective.
