We're doing 802.1x with LWAPP. We have two controllers, 300 APs and average around 1100 concurrent wireless users.

We just switched to 802.1x authentication last year, with great success. Previously we ran a network with just WEP and MAC address registration. Last summer we brought a new wireless network up on the controllers supporting WPA1 and WPA2 with TKIP and AES enabled. We then turned on a captive portal on the legacy network that redirected users to a website containing information on the new network and a switch over date. The users could choose to see the directions on how to switch, or continue using legacy network up until the switchover deadline.

A big factor in the 802.1x puzzle that will determine the success of your project is your EAP method. We chose PEAPv0 as it had the greatest compatibility in our environment and lowest overhead. Hope this helps!

How many others are doing 802.1x in a Cisco LWAPP environment? Have you had success with it, or would you recommend another route for authentication? Currently we are using VPNs over our secure wireless and I am investigating whether we would be ahead to start using 802.1x coupled with WPA. Any thoughts would be appreciated.

Thanks,

Matt
