NO CoA request

Hello experts,

I just configured wireless Guets access on WLC/ISE and getting the below error:

11213 No response received from Network Access Device after sending a Dynamic Authorization request

Here are my policies:

Authentication:

MAB : If Wireless_MABAllow Protocols : Default Network Access and

Default

use

Internal Endpoints

Authorization:

Phase2-Redirect-Access if GuestType_ActivatedGuest-30D AND (Wireless_MAB AND Radius:Called-Station-ID CONTAINS GM_CWA AND Network Access:UseCase EQUALS Guest Flow ) then PermitAccess

Phase1-Redirect if (Wireless_MAB AND Airespace:Airespace-Wlan-Id EQUALS 4 ) then CWA_WebAuth

could anyone help to troubleshoot!!!

Thanks in advance:

Hi,
Have you configured "Support for RFC 3576" on the WLC?

Security > AAA > RADIUS > Authentication

This page shows how to enable
