Explanation

The issue described occurs when the fallback feature is disabled on the Cisco AireOS controller. When fallback is disabled, the controller does not attempt to reconnect to the primary TACACS+ server after it becomes available again following a failure. Instead, it continues to use the secondary server until it fails or the controller is rebooted. Enabling fallback would allow the controller to periodically attempt to reconnect to the primary server.
