FreeRADIUS with WLC 8.3.122 per user bandwidth rate-limits

[Marty Harrison]

Hi,

I am using FreeRADIUS to authenticate users on a single SSID. I can allocate them to particular VLANs etc. What I would like to be able to do is to allocate the users specific QOS bandwidth limit overrides. This should be possible and I can find all of the Cisco documents that reference the Cisco AV pairs. I have no idea how to format it in the FreeRADIUS user file. For example, to allocate a VLAN I just add the following lines;

	Tunnel-Type = VLAN,
	Tunnel-Medium-Type = IEEE-802,
	Tunnel-Private-Group-ID = "3",

So what do I need to add to allow a bandwidth limit of for example 20mb?? I have tried lots of different options e.g.

cisco-avpair = "ip:Airespace-Data-Bandwidth-Average-Contract-Downstream=20000"

 I am lost. Any help would be gratefully received.

Thanks

I have managed to figure most of this out....

The freeRADIUS dictionary.airespace file did not contain definitions for the values I was trying to apply which is what was causing half of my problems. I have added those definitions so my file looks like this

Now I can call those values with commands like below;

Airespace-Data-Bandwidth-Average-Contract = 20000
