"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If you want to use CWA Guest portal, for example, you're out of luck.  You can, however, integrate the 4400 with an ISE as a pure RADIUS server.  CoA is supported with and later versions of code.

This means you won't be able to use the centralized guest portal for guest logins.  You'd be stuck to using the local web-auth feature and backing off to RADIUS for authentication.

ason is

We have now installed a 5500 series controller. I'm trying to authenticate to the ISE, but am getting rejected due to CHAP not allowed. Configured to allow CHAP under the Policy Elements, but still getting same rejection "CHAP not allowed"

Connecting as a guest/client. After some tweaking and reviewing logs, I finally have it authenticating. Thanks for the suggestions...

Now able to connect to Guest Wireless, after authenticating through the Cisco ISE appliance. But, once i receive the "you are now connected to the internet" message, I'm unable to load the pages, on any site. The same subnet cureently works for users connected via ethernet, but not for wireless

Are you giving a DNS server address to wireless clients?
