Hi,

From what I know this is to do with DHCP option 60 and 43.Normally when APs request for IP address, DHCP Server also returns the management IP Address of WLC if the VCI matches.

If the VCI sent by the AP does not match with the one configured under DHCP for that particulart AP type, the DHCP will never return the WLC IP and hence AP can not find the controller.And the AP keeps sending DHCP Req and sometimes end up getting two IP addresses!

So may be you can check VCI on DHCP server for that AP model.

Let me know.

 

Cheers
