Communicate APs with controllers Loopback Interface

[Maksim]

Hello!

I want to use controller Loopback Interface to communicate with APs. 
Through Vlan 1 APs works well.  When I use the Loopback interface as  Controller ip - APs dont find controller. ADP dont work. I think it's because Loopback IP address and APs IP address are in different networks.

How to properly use the Loopback to communicate with the campus APs?  Or it should only be used for remote APs?

Thank you.

You do not need a loopback interface.  You just need to designate a single interface on the controller as the controller-ip and that is what the APs will communicate with.  http://www.arubanetworks.com/techdocs/ArubaOS_6_5_4_X_Web_Help/Web_Help_Index.htm#ArubaFrameStyles/Network_Parameters/Configuring_the__IP_Addr.htm?Highlight=controller-ip
