I needed to verify the startup CAPWAP configuration before delivering a Lightweight AP far far away.

1. Boot a CAPWAP AP without connecting the network (It takes longer due to 2 or 3 timeout waiting for PHY).
2. Connect to serial console.
3. Login verifying the password from controller are successfully stored.
4. Enter enable.
5. If you configured a static IP verify it with
   show capwap ip config

LWAPP Static IP Configuration...
   
6. Issue
   show capwap client config
   and search in particular for the following lines
   ...
     mwarName                  wlc.mydomain.it
  mwarIPAddress             8.8.57.215
   ...
     Configured Switch 1 Addr  8.8.57.215
