Adding Cisco AP's to NPM

This is probably a crazy question, but here it goes. How do I add my Cisco wireless access points to NPM? They do not have IP addresses as they are being managed by a Cisco 5508 WLC. I have enabled the generic "Alert me when a Rogue Access Point is detected" alert, and the alert is firing on all of my AP's:

"Wireless Controller Avn5250-C108-5508 detects 183 Rogue Access Points."

Thus, there has to be a way to list my valid AP's as non-rouge.

Any thoughts on this would be greatly appreciated,

Jon
