How to do I prevent fail over

Question

This is actually a two part question.
First - I need to upgrade a wireless controller 4402 and I need update boot loader and software. Can I do both at the same time?
Second - How can I prevent the APS from failing over when I reboot with out having to go into each AP and take off secondary controller.

Answer 1

Specific to the AP failover. Why dont you deploy AP FALLBACK? When a controller falls offline for
any reason the APs join other controllers. HOWEVER when the controller comes online they will fallback to the controllers
you want with NO intervention from you.
fyi
NoteWhen an access point’s primary controller comes back online, the access point disassociates from the backup controller and reconnects to its primary controller. The access point falls back to its primary controller and not to any secondary controller for which it is configured. For example, if an access point is configured with primary, secondary, and tertiary controllers, it fails over to the tertiary controller when the primary and secondary controllers become unresponsive and waits for the primary controller to come back online so that it can fall back to the primary controller. The access point does not fall back from the tertiary controller to the secondary controller if the secondary controller comes back online; it stays connected to the tertiary controller until the primary controller comes back up.
