WLC 2504 7.5 Redundancy

[fbarthlmy]

Hi all,

Just a little question about high availability in cisco 2504 WLC Ver 7.5.102.0.

Following the cisco documentation for WLC I want to set the HA configuration by going to Controller - Redundancy menu. My issue is that this menu does not exist in my WLC.

Anyone know if this version of ios is HA capable or not ?

Thanks

Fabien.

The 2504 only supports N+1 and not AP SSO. Here is a link for N+1:

Thanks for your quick reply Scott.

With HA N+1 if my first WLC fail all my licenses will be moved to the second WLC ?

Thanks.

Hi,

When the active controller is unavailable, the standby controller will adopt the licenses from the primary controller. It is expected that the you will be able to get the primary controller back online within 90 days. After 90 days, the you will get a daily reminder to switch back to the primary controller.

That is the process. That's why the HA sky is cheaper.... You don't buy licenses.

Just make sure you have activated one of the licenses on the HA WLC by changing the license priority and accepting the EULA.
