How to limit bandwidth on a per user basis?

[Mottok]

Good morning, we have the following setup on our 5520 controller using ISE 2.2 as the AAA server. As our network engineer left I know nothing about this setup but have been asked to look in to limiting bandwidth on a per user basis, would it be possible to provide an idiots guide to this (if you need further info just let me know)? not even sure if this is done on the controller or ISE. Would be very much appreciated thanks.

Thanks for that, first one I'm totally lost on, the second I was looking at earlier. It seems straight forward enough to change the section below to limit bandwidth on a per user basis however it also says "16 Override Bandwidth Contracts parameters are specific to per Radio of AP" - so is this bandwidth override per AP or user??

I'm hoping it's as simple as changing the settings above to override bandwidth on a per user basis, can anyone confirm please? Many thanks.

That's an excellent article thanks very much. So it looks like it sets a base per radio on the AP for each client however if there are less clients it will increase the bandwidth somewhat. It doesn't say what happens if there are any more than 2 clients on a single radio but I'm guessing it wouldn't drop below the specified bandwidth.

Maybe have to look in to doing this at the firewall as the article suggests. Many thanks for your help.
