WLC 4402 software version: 6.0.188, licenced for 12 APs.
I have five Cisco 1250 lightweight APs. Added 4 successfully to the controller, the 5th one will not add and get the following errors on the controller:
*Apr 15 17:08:55.407: %CAPWAP-3-AP_DB_ALLOC: capwap_ac_db.c:145 Unable to alloc AP entry in database for 172.16.31.5:30798
*Apr 15 17:08:55.407: %LWAPP-3-AP_DB_CREATE_ERR: spam_lrad.c:5183 Unable to create an entry for AP 00:00:00:00:00:00 in the database - invalid mac address
I have done full reset of this access point, but still no luck.
