You can set upper and lower thresholds (in percentages) and drop probability for a flow-WRED object on a device. If the flow queue (FQ) length exceeds the upper threshold, the device randomly discards packets using the WRED mechanism.
If you want to use a non-default flow queue (FQ) profile, you need to configure WFQ scheduling weights, traffic shaping, a shaping rate, and a way of dropping packets according to network requirements.
Applying a service profile to an interface and configuring precision compensation achieve precise flow control by compensating for a processed packet with a preconfigured length.
A PIR value used for traffic shaping can be set for a GQ to limit the volume of GQ traffic and prevent GQ traffic burst. In this way, traffic can be evenly sent.
After a VPN-based QoS profile is successfully configured, you can view information such as the configurations of an FQ profile and a QoS profile as well as the application of a QoS profile.
