Dynamic VLAN Assignment + NPS

[Evan Wheatley]

Hello,

I'm planning a deployment with the following:

5508 WLC running 7.0.222.0

NCS 1.0.2.29

50+ 3502i AP's

Windows 2008 R2 running NPS

EAP-TLS for authentication

The end goal is to have a single SSID and utilize NPS to dynamically assign VLAN's depending on role/group.

I've read several documents that use ACS to complete the dynamic VLAN assignment (inclduing http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a008076317c.shtml), however in this case ACS is not available.

My question basically is; do I need ACS to apply the VSA for Cisco Airespace, or can this be done solely with the following IETF attributes using Microsoft NPS and AAA override on the WLC?

[64] Tunnel-Type

[65] Tunnel-Medium-Type

[81] Tunnel-Pvt-Group-ID

Any advice would be greatly appreicated!

Thanks

You don't need to use the Airespace VSA, the IEEE standard 64/65/81 will work.

Just to follow up, I've successfully implemented this and the client is happy with the outcome of the project.

Thanks for your help Steve.

Hi,

I did exactly how you guys stated and it still not working.

I have 3vlan in the wlc, do I configure 3 ssid or 1 ? I have multiple vlan.

Please give me some screenshot of the WLC configuration.

Thanks

[Stephen Rodriguez]

You only need to configure one SSID, and make sure you have AAA override enabled in the WLAN config.

If you are doing 802.1x and have the NPS configured to return those attributes it should work

HTH,
Steve

Thanks Steve for your quick response.

I did everything as per your recommendation and it still doesnt work.

Do you mind providing me a remote assistance, do you have Skype?

Or your prefer that I provide you a set of logs, tell me which one and I will do so.
