Hello
I'm trying to get a solid understanding of the Master-Local controller deployment in terms of failover. I've been looking at documentation and I see what each role is responsible for, but not much about failover. So if you have a Master-Local deployment and the Local fails, will its APs begin to terminate on the Master? I assume/hope that this is true as it seems too logical to not be. But what about the other way around? If I lose the Master will they failover to a Local? I assume that this is not true but I need to ask. In that scenario I'm sure it would be best if "business crictical" enough to drop in another controller as a standby for the Master.
Maybe a Master-Local isn't even the right type of controller deployment for my scenario. I have a handful of small sites that I was going to terminate on a Master (~20 APs) and then I have a main site where I was going to terminate their APs on a local (~20 APs). The concern of course if failover so would I be best served to do an Active-Active deployment?
Thanks for reading!
