Hello,
I'm running WLC 2504 with AirOS 8.2.151.0.
I've configured CWA with FlexConnect (refers to this doc : http://www.cisco.com/c/en/us/support/docs/security/identity-services-engine/116087-configure-cwa-wlc-ise-00.html)
When I used the guest SSID with a localy switched mode there is no connectivity. When I used this wlan with a centraly switched mode all works well.
I have made one debug client for each of this test (attached).
I don't understand what is the matter. I double check the port switch configuration (wlc LAG versus AP port switch).
