I have the following issue with one controller AIR-WLC2112-K9 with 2 LAP .When I ask the info by GUI for the the LAPs in Wireless ----> AP name (click) ---->General the info displayed in "IP config" does not match, for the field static IP is shown the IP 172.18.98.2 but the line above "IP address" shows 188.8.131.52. Controller has IP 184.108.40.206
I verified by console with the command show lwapp ip config and the IP is correct. 172.18.98.2.
This is a well-know and well-documented issue of the WLC that you can't set static IP to an LWAP. I'm using 220.127.116.11 and it's hit-and-miss. What firmware version are you using?
