On this command which IP address do I use? ap-manager? or management?
It should be the "WLC management IP address".
Search for "If necessary, issue the lwapp ap controller ip address A.B.C.D" in the above link.
Hope this helps.
It looks like you are staging an AP. I would use the management address. Someone please correct me if I am wrong this, I haven't had to do this since 3.x
