I know a there are a lot of discussions on this topic but I did not see anything that matched this issue exactly.
I am implementing Wired 802.1x/MAB/WebAuth with Clearpass and Cisco switches. 802.1x and MAB work well. I am having difficulty with the URL Redirect when using HTTPS.
I am able to properly send a URL Redirect and a URL Redirect ACL to the switch. These work great if the client tries to browse to a HTTP URL, they are properly redirected to the Clearpass URL.
If a client attempts to browse to an HTTPS URL, the browser says it cannot reach the site. Both IE and Chrome exhibit this issue.
I have IP HTTP SERVER and IP HTTP SECURE-SERVER enabled on the switch. I have tried various versions of iOS.
This seems like a Cisco bug but I would think others would be running intop this same issue.
I have tested on 3560, 3750, 3850 with a few different iOS versions.
