ISE setup error

I have a demo ISE server running 1.2. I cleared the database and am running the setup wizard through the web mgmt. In the network devices portion of the setup I selected the switch and WLC I have on my lab network, but I get an error that says something like "Cannot create WLC. IP address already exists." I created 4 different VLANs for users/guests; wired/wireless and different SSIDs for users/guests...which I should really need to do with ISE, right? Anyway, I wanted to be sure I wasn't using the same IP address for any of the options in device setup. The only issue I could possibly think of is that I'm using the same VLAN for the management interface of the switch and WLC as the wired users.

Any suggestions?

Re: ISE setup error

So it seems you are thiniking correct, In ISE you cannot add same IP/radius client twice. You may also need to check in case you're using default device definition when no specific device definition is found for a RADIUS request.

Re:ISE setup error

I think I found the problem. In the device setup, I used /24 on the address of the switch and WLC, as directed by Cisco's ISE book. It should be /32.
