Proritize Wireless traffic per WLAN

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.

Re: Proritize Wireless traffic per WLAN

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.

Re: Proritize Wireless traffic per WLAN

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.

Re: Proritize Wireless traffic per WLAN

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.
