Can you confirm this is true if a single device or router has multiple IP addresses?
The reason I ask, is that our 5400's have dozens of addresses on them, but when I do a network scan, it reports it as not added and can't due to us running out of licenses.
Also, our Aruba IAP's have a device IP and the one with the Virtual Controller role also carries a Virtual IP for management. These are seen as two seperate devices in IMC.
