Testing took place at the University of Florida’s Network Services Interoperability Lab located in Gainesville, Fla. Each vendor brought two wireless switches and at least four access points, which I set up on isolated networks in the lab. I used Cisco and Extreme switches with both 10/100 and GbE (Gigabit Ethernet) ports for connectivity between wireless switches.
I performed rogue client and AP (access point) detection by bringing unregistered APs and clients online after switch-controlled networks had been deployed and configured. Performance testing consisted of using a variety of IBM and Dell laptop computers with 802.11b network interface cards, which began looped file transfers using FTP. I observed throughput rates while no additional clients associated with a given AP, and while additional clients associated with the AP. Traffic for performance testing and rogue client detection was generated by a variety of IBM and Dell laptops outfitted with a variety of Cisco, Orinoco and NetGear wireless NICs (network interface cards), in addition to the wireless NICs internal to the IBM ThinkPad computers. Cisco and D-Link access points were used for testing rogue access point detection, while Cisco access points were employed for generating background network traffic to simulate a nearby WLAN.
