My setup is basic with ap-manager and management interfaces both untagged and two dynamic interfaces on VLANs 1 and 2. The WLC2106 is connected to a L3 C3560 through a dot1q trunk native VLAN 4. Ap-manager and management interfaces are managed from VLAN 4 with no problem. VLANS 1, 2 & 4 are on different IP subnets. Problem is I need to use a RADIUS server on VLAN 1 but the WLC can't ping the server on VLAN 1.
I have seen similar queries which do not give a definitive answer e.g. http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Wireless%20-%20Mobility&topic=Getting%20Started%20with%20Wireless&CommCmd=MB%3Fcmd%3Dpass_through%26location%3Doutline%40%5E1%40%40.1ddf8d3e/3#selected_message
