Conditional statements FreeRadius

Hi there,

I set up my FreeRadius server at my company and so far we figured out how to send VSA to our Aruba controller and so forth. Now we would like to implement some "conditional statements" like , if EAP/PEAP ok and @mac ok go to secure network, if EAP/PEAP ok and @mac is unknown then GO to BYOD network.

So we understand that we would need to do those statements with "Unlang" from FreeRadius , do you guys have some references, examples that we might use ?

Cheers!
