Cisco 2504 Wireless Controller Redundancy/Failover

Our old 2112 controller failed so we now have two 2504's to allow for redundancy and failover should one pop.

However I have been unable to get them working in this way (or know what to expect).

At the moment they appear to be operation separately as I lost 2 APs off of the 1st controller only for them to appear on the 2nd.

Could anyone explain the process? Via CLI/SSH or web?

Via the web, the Redundancy Mode is currently N/A which I assume will show enabled when correct?

Thanks in advance.

Configure the Mobility and RF domain names the same on the Controller Settings page.
Configure Mobility between the two controllers.

This will enable the controllers to share their info (APs connected, clients, RF etc) and manage the wireless network more effectively.

The redundancy mode requires you to configure one of your controllers in HA mode and requires a layer-2 link between them.  If you have two controllers with licences you'll lose them whilst the controller is in HA mode.
