We did load testing on our RADIUS servers for the same reason about three years ago. We used Spirent/Avalanche to generate RADIUS traffic with randomized MAC addresses. It gives nice graphs that show the number of authentications per second that a server can take, etc. It was quite helpful. Another tool we used was just the freely available EAPOL supplicant, but the Spirent was more along the lines of what we needed.

One of the problems we are having is coming up with a reliable and realistic way of testing them to make sure that they are able to handle the load our wireless network is going to throw at them. I was curious if anyone had any testing frameworks or methodologies they have used in the past to test performance and conduct load testing on RADIUS servers. I'm ultimately looking for a solution that simulates 802.1X EAP-TTLS/PAP requests at the peak rate coming from our controllers.
