Hi,
I have WLC 2504 with 2 SSID and about 12 APs connected.
Now i have been tasked to add a second WLC 2504 as backup.
I have never done this in the past and even the first WLC was done with the help from someone here.
I have tried to match the second WLC as close as posible to the fist one and I an access it through browser but it is not working.
I have checked this in the first WLC
Under wireless tab---->ALL AP and the under the AP in High Availabiliry I have set the 2 controllers
Please see the name and ip address of the Controller above.
I am not sure what to put here under Wirelss--->Global configueartion and the warning said that once the ip is set it cannot be removed that is why I need some help.
can somone please help me or let me know how to do the HA if I am going in the wrong direction.
Thanks

Take one AP for testing and swap primary & secondary controller configuration high availability tab. In that way, you can test whether 2nd WLC accepting AP registration.
Check WLC time, WLC licences, Country Code on 2nd WLC, if you have issues of AP registering to it. Pls attache AP console output while it is trying to register for 2nd WLC in the above scenario.

You can ignore that wireless-> global config, it takes preference for Primary & Secondary configuration under AP High Availability. Pls make sure you use the exact sysname of your WLCs in that section (Name setting of that High Availability config)

Hello Rasika,
Thank you very much for your reply.
There was a mistake in the sysname and I have corrected that.
Please see e attached file.I cannot see any AP in the WLC_SECONDARY controller.
Thanks

The AP will move to the secondary WLC if the primary goes offline.

Hello Rasika and All,
Thank you very much.
The issue was the country code, Date and Time. I struggle a lot to change these setting as I did not know how to do it but read forums and finally now I know how to do it. Once I change those 2 settings and simulate an outage on my primary WLC I could see all the APS registering with the secondary WLC. I then brought the second WLC out of service and all the Aps went back to the Primary WLC.
The only hic here is that although all the Aps could be seen on the secondary WLC I could not see the SSIDs on any device hence could not browse.
Thanks a lot
