Hello,
I've 2 Physical WLC 9800 in SSO, and I'd like to know if it's possible to monitor the Management AP Interface to force a Failover if it's not reachable.
I physically shutted the Interface that carry the AP Management IP to see what's happening, and all my APs were losing connectivity to the WLC.
I find it a little surprising because the interest of Redundancy should be to overcome this kind of issues. If the AP management interface isn't reachable, the Primary Controller should switch to guaranty the continuity of services.
Do you have any ideas?
thank you,
best regards

how are the 9800 connected to the wired network?
is this a physical appliance?
what code are you running on the 9800 WLC?

Hello,
I'm using physical appliances, the RP for redundancy and a Chanel Group of 2 TenGig Interface for AP Management and SSIDs.
I understand you're explanation about SSO. But I still find wierd that if AP can't join the WLC, it doesn't try to failover.
As I'm using the RP for Redundancy, the SP for OOB Management and 2 ports fort AP Mangement, I can't mutualise those interfaces. That's why I'm looking for a trigger to force failover when APs can't join WLC anymore.
Thank you,

How do you have the physical WLC's connected? You have to run the heartbeat cable through an upstream switch based on your IOS. If you are running 17.2.1 or higher then you can consider running the Heartbeat cable directly connected
