Hello!

I have two wifi controller 5760 and AP Lightweight Access Points. I configure one controller and works fine now.But I want configure wifi controllers support failover. If one primary controller is down, working secondary and all setting transmitted to AP AP Lightweight Access Points. How to do this? is it possible to this model?

yes its supported.

Here is the guide to implement HA:

I understand that, if they connect to the stack cable but this not my case, they are in different room

Ok. For real HA (AP/Clinet SSO), It is highly recommended to have back-to-back direct connectivity between Redundant Ports."

If you dont have direct layer 2 connection between these controllers then you can use N+1 HA method.

in N+1 you must have enough AP licens eon both WLCs. so that..

AP can be configured with primary, secondary, and tertiary controllers. When the primary controller fails, depending upon the number of APs managed by a controller, the access point fails over to the secondary controller. Once it detects that the primary controller is unavailable, the AP rediscovers the controller and reestablishes the CAPWAP tunnel to the secondary controller.

If I correctly understand, that at each point to configure and enter into manual where there will be a primary and where the second controller ?

Yes each AP must be configured manually with primary /secondary WLC IP and name.

step 1. Configure two controller each (create vlan, configure int )

step 2 Create mobility group, each controller (add vlan and wlan )

step 3 Configure all ap manual ip primary and secondary controller

Tell me please my actions are correct?

Correct.

Configure both WLCs identical except IP address and Hostname.

also Add each other (WLCs)in their mobility groups.

and last configure all AP manually for primary /sec/tert.

Example:
