Cisco Controller Behavior

[AhmedElshindidy69185]

HI All,

my question is very simple , if i have single controller in my environment, what's the normal action happens to access points managed by it, when the controller is rebooted or power failed? campus access points continue its functions normally or it reboots?
is there any documentation for this?

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

[AhmedElshindidy69185]

no redundant WLC,
would you please inform me of the two cases? (flexconnect or local)
and breifly the difference between these modes

Read Information About FlexConnect.

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.
