How to configure the user-based rate limiting on WLAN devices
Configure the user-based rate limiting on APs:
Configure traffic policing in a traffic profile to limit the traffic rate of all STAs or a single STA on the VAP using the traffic profile.
<Huawei> system-view
[Huawei] wlan 
[Huawei-wlan-view] traffic-profile name p1 
[Huawei-wlan-traffic-prof-p1] rate-limit vap up 64 //Rate limiting of upstream packets of all STAs on a VAP   
[Huawei-wlan-traffic-prof-p1] rate-limit client up 32 //Rate limiting of upstream packets of each STA on a VAP  

Configure traffic policing in a user profile: Bind a QoS CAR profile in a user profile. Then bind the user profile to a service set to limit the traffic rate of the user bound to the service set.
<Huawei> system-view
[Huawei] qos car c1 cir 10000 cbs 10240 //Configure the CIR and CBS value.

Configure rate limiting based on IP addresses
You can run the qos car command in the interface view to configure rate limiting based on IP addresses.

Do S series switches support rate limiting based on applications
