Solved: Re: Wired CWA with ISE 2.x and 2960X switch 15.2

kidvelvet · ‎02-07-2017

Hello,

I have setup for a customer a wireless Centralized Web Authentication portal that uses AD authentication in order to access the proper network resources (customer does not want to use a dot1x client, so we are going the web auth route). This has worked as expected, and now we are just putting some finishing touches on the configuration to get the workflow just right.

However, when I try the same thing on the wired side with a 2960X using 15.2.2 code, I seem to get all the MAB authentication to work properly, the switch gets the correct guest redirect URL and ACL, and I am able to connect to the https://guest.example.net:8443/portal<redacted> site when entered manually, but going to 80 or 443 will not cause a redirection.

Here is the relevant switch configuration:

Are you sending dACL as well? If not then I would send 'ip permit any any' dACL along. Looking at your ACL-DEFAULT, you have 'deny ip any any' which is denying any web traffic destined for IP other than ISE. sending the 'ip permit any any' should address that.
