Proritize Wireless traffic per WLAN

JASON SIMMONS — Sun, 04 Jul 2021 07:32:42 GMT

I have 3 WLANs setup. I want the traffic (any traffic) to have proority over the other 2 WLANs. What do I need to do to accomplish this?

Do I just set QoS on WLAN to platinum and leave WLAN2 & 3 at silver? Currently they are all silver.

Yes, you can do that. Then it will allow that WLAN to preserve upto CoS =5 (DSCP EF). Depending on the wireless client traffic classification (WMM UP) different traffic type will get different type of CoS value within this WLAN. If you want all traffic to get CoS =5, I think (hv to confirm once I test it) you have to disable WMM under QoS section for this WLAN (note this would impact 802.11n data rates).

As long as you keep other two WLAN's profile to "Silver" all traffic will be capped to equivalant CoS of 2 max.

There is difference between WMM UP & AVVID 802.1p (CoS) values. Please refer this if you get confused

Also you need to remember to configure your wired network for QoS if you want to keep QoS end to end.

I have tested WMM disabled option for you. In that case all traffic will be marked with appropriate DSCP/CoS value as per QoS profile configured. In your case once you disable WMM on your platinum enable WLAN all traffic will get marked as EF.

Here is my testing details for your reference.

or you can override oer user/ per ssid bandwidth

Hello Jason,

As per your query i can suggest you the following solution-

QoS provides enhanced and predictable network service in the following ways:

Supporting dedicated bandwidth for critical users and applications
Controlling jitter and latency (required by real-time traffic)
Managing and minimizing network congestion
Shaping network traffic to smooth the traffic flow
Setting network traffic priorities

For more information refer to the link-

Hope this will help you.
