Configuring Remote AP Failback
In conjunction with the backup controller list, you can configure remote APs to revert back (failback) to the
primary controller if it becomes available. If you do not explicitly configure this behavior, the remote AP will
keep its connection with the backup controller until the remote AP, controller, or both have rebooted or some
type of network failure occurs. If any of these events occur, the remote AP will go through the backup
controller list and attempt to connect with the primary controller.
In the WebUI
1. Navigate to the Configuration > Wireless > AP Configuration page.
2. Select either the AP Group or AP Specific tab. Click Edit for the AP group or AP name.
