Were you trying to contain rogue AP's? You can still detect the rofue AP's without RLDP. With RLDP, the AP will try to associate to the rogue ap and that is why you are seeing the interface go up and down.
You should be able to see rogue AP's without rldp enabled. Just leave it disabled for a couple days and see. If you look at the doc I posted, if you want to use rldp, then you need to take the ap out of local mode and that ap will not service clients. So bottom line is... if you want that ap to service clients, then disable rldp or purchase another ap for rogue detection.
This is how I have mine setup and I can detect rogue aps and ad-hoc network. Take a look at the following screen shots and setup yours the same way and let it run for a couple days. This is how you need it to be set if yo want to service clients.
