1) What is the difference between the AP manager interface and dynamic Ap manager interface?
2) i was enabled the AP manager i wants to integrate one AP with WLC. so which ip is the WLC ip for the basic configuration, i mean Ap manager interface ip or management Ip of the WLC.

1) Dynamic interface be default is not AP maanager (used for AP registration) but it can be abled to behave like AP manager. If you deal with recent renough hardware, you would not see dedicated AP manager interface any more. Instead it became Management Interface which has AP manager function enabled by default.

2) Depends on your WLC. Most recent WLC only has Management Interface and you should point AP to that unless you also enable dynamic interfaces to also be AP manager.

can you please explain briefly about the NAT option?

You only need this there is NAT device between WLc and AP and WLC is NATed. You supply WLC with NAT IP so it can include it in CAPWAP response to AP.
