How do you get the AP's active tunnel to switch between controllers? We had one controller go down awhile back and the APs connected to the other controller with 0 issues, but now they won't go back leading to all the clients being on one controller. I thought they would switch back automatically after the controller came back up, but it has been quite some time and they have not. Is there a way to force the APs back to their controller as the active tunnel?
