qos-mode {disable | priority | round-robin}

If you have a FortiGate with one or more NP7 processors and an internal switch fabric (ISF), you can use this command to configure the QoS mode to control how the ISF distributes traffic :

config system npu

set qos-mode {disable | priority | round-robin}

end

Where:

disable (the default setting) disables QoS for NP7-accelerated traffic.

priority uses priority-based QoS that is applied to ingress and egress traffic based on the traffic CoS value. Traffic with a higher CoS value has a higher QoS priority.

round-robin applies round-robin or bandwidth control distribution to ingress traffic only based on the traffic CoS value. This mode helps smooth out incoming burst traffic by distributing traffic evenly among the NP7 processors.
