Have came accross a pretty odd scenario - a LAP has joined WLC1 on location 1 with no problem - client needs to change this LAP over to location 2 where it should join WLC2 - location 2 has more LAPs that have already been associated with WLC2 with no problem however this just introduced LAP would not join WLC2 but keep on joining WLC1. Option 43 settings with DHCP have been set up correctly - wouldn't this LAP join WLC2 when is moved to location 2 automatically using DHCP Option 43? Does LAP need to be converted to autonomous so it would not keep joining WLC1? Tried to reset configuration on LAP through WLC1's GUI as well as WLC's CLI - even though LAP configuration is reset to factury defaults, AP reboots and it keeps on joining WLC1 - not able to change anything on LAP through CLI either as AP is blocked (ERROR!!! Command is disabled) as soon as it reboots and joins WLC1.
Any input on the Cisco Support Community out there???
You are correct, however, if you put the details of WLC2 (name and management IP address) into the Primary Controller field, the LAP will immediately go and join WLC2.
