Switchover Reason on WLC 8500 Series

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

When switchover occur , from active to standby unit , can be configured to send some notification ?

Via trap , email or simillar ?

Trap?  Yes, using SNMP. 

Not sure about email but it should be possible with PI or other 3rd party software which, coincidentally, uses SNMP traps.
