Trying to Configure a RADIUS server 2008 r2 to house a set of Mac addresses that are allowed to connect to the network. I'm using Cisco aironet 1142N. I'm pretty new at this and will need some major help. Thanks to anyone who can help.

Software/Hardware used:
Windows server 2008 R2 / Cisco Aironet 114N Autonomous mode

Hi JKuo and everyone,

Reading your question, one can keep some further questions about your setup. So YMMV. Here I assume you already have the wireless connections and RADIUS authentication in place and working flawlessly.

I will try to provide some guidelines for what I think maybe fit your scenario.

When anyone talk to me about filtering/mac filtering network access in a Windows network (starting on W2k3 Server) I always tend point the DHCP Callout feature.
This is included in W2k8 R2 Server, but also available to install in a W2K3 Server as well. This works very well!

Basically, after configuring the DHCP server Callout feature described here, you just have to maintain a simple text file in which you put only the ALLOWED/KNOWN mac addresses to your installation.

You can always configure RADIUS filtering in the access point or in the RADIUS policy itself. But if your setup is some king of static, the overhead, may not justify…

Let me know if you need something else.

HTH

    Two types of MAC authentication that are supported on WLCs local MAC authentication  MAC authentication using a RADIUS server are stored in a database on the WLC. When a user tries to access the WLAN that is configured for MAC filtering, the client MAC address is validated against the local database on the WLC, and the client is granted access to the WLAN if the authentication is successful.
