Local APs are totally dependent on the controller for their functionality. Simply put, if the controller is not live on the network, the APs are down.

 

FlexConnect is a semi-autonomous mode where the AP is configured to work with the controller when it is available, but can function if the controller is not live. But it takes additional configuration for this to work.

 

This is a very basic and simplified explanation. If your environment  relies on the wireless it would be best to have a second controller.

Depends on how the AP is configured: Local or Flexconnect
Is there a redundant WLC?
