QOS settings in WLC

[scariarajan]

We have a 5508 WLC managing 45 access points distributed across our 15 offices. We have 3 SSID's configured on all access points and have QOS setup across 2 of these SSID's.

The issue we are facing is that we have different WAN bandwidth at each of these offices and so want to set up QOS based on this, that is the location of the AP.

What's the best process to address this issue without having to create SSID's specific to each of the offices.

QoS settings on WLC helps you to manage QoS for wireless frames, not help you to control bandwidth usage across WAN.

If you monitor the CAPWAP protocol traffic across WAN you can get an idea how much bandwidth your wireless traffic consumed. (assuming all these SSID are centrally switched and no flexconnect APs)

Hi Rasika

Not sure if you really got the issue we were facing. Site A has a 20MB wan link and Site B has a 3MB link. So we want to enfore per user bandwidth restriction depending on the site link. 

Also pur AP's are operating in flexconnect mode.

I presume you have one AP group per site? If so you could create one WLAN per site (using WLAN IDs 17+ they can all have the same SSID) you can use rate limiting on the QoS tab of the WLAN to control wireless client traffic. In this case you would set the per-SSID for WLAN profile name SSID-Site1 to the bandwidth of site1.

Thanks Martin. This will work for us and appreciate your help.
