regarding AP Fallback for 4.0 code:
If a primary controller has failed and then comes back online does the AP re-join automaticaly with loss of service?
Thanks

So if the original controller becomes avaialble does the AP join to it automaticaly and is service affected?
Yes. There's a loss of wireless services during the switch over from the secondary/tertiary controller back to the primary controller.
NOTE: Just make sure you configure the primary/secondary/tertiary controllers correctly. During my "playing around" with the 4.0 the configuration of the primary/secondary/tertiary controllers using GUI does not work. The primary/secondary/tertiary controllers details (IP address and WLC names) need to be entered via CLI.

Hi,
If the access point was previously associated to a controller, the IP addresses of the primary, secondary, and tertiary controllers are stored in the access point's non-volatile memory. This process of storing controller IP addresses on access points for later deployment is called priming the access point.
The APs are supposed to join back to the WLC..
lemme know if this answered your question..
