Just wondering if there is an easy solution to this. We have ClearPass configured with our Aruba controller and our legacy Cisco WCS controllers to feed guest/byod captive web portals, and since connecting the WCS controllers as Radius clients, every connection made to the captive portal WLANs, regardless of captive portal authentication state, is showing up as an active session in ClearPass and flooding it out until it won't hand out legitimate connections anymore. They show up with the mac address, no session time, and zero data. The Aruba controller is performing normally in this regard, so I feel I can probably eliminate ClearPass as the issue.
I've tried turning down the session timeout on the Cisco WLANs and that's worked, somewhat. However a lot of devices will just re-scan and jump right back on.
Has anyone seen this type of problem before and knows what magic combination of buttons will make the Cisco controllers cooperate with ClearPass?
