Wondering if anyone knows the solution or have had my experience. I have been configuring quite a few WLC controllers recently. I have good results but there is one problem that seems to pop up in every installation. I set the WLC in Layer3 mode. Configure the VLANS and DHCP correctly. The 1010 AP's get IP address and try to register to the WLC but debugging in WLC says always Discarding Layer3 blah. I have tried to change the WLC to Layer2 mode and put the AP on that subnet and then It connects, downloads software and config and is OK. If I move it back to Layer3 and move the AP back everything is OK!
Next new AP does work over Layer3 and I think it is because of the "over the air provisioning" feature that it learns from the neighbour AP over wireless where the WLC is and how to connect via Layer3. Obviously my DHCP and routing is correct since it works after changing it back from Layer2 mode.
Anyone had the same experience ?
