Hi,
I have configured HA redundancy on 2 units WLC 8500 series with SSO. After running for more than 6 months, the WLCs have been switchover several time and the switchover reason was "Active Controller Failed". Does anyone know what it means and how to see the details of the switchover reason? I want to know why the Controller failed and what cause that.
Thank you
Regards,
Arie
