local vs cloud ppsk outage behavior

[nweil]

I want to use local ppsk across multiple sites. If connection to the local ppsk server at site 1 is lost does authentication stop for users ate site 2? Or doest the local ppsk database get propagated to all aps?

question 2: when utilizing cloud ppsk during a a WAN outage are only new authentications affected? Do currently authenticated device continue to communicate with the LAN?

Local PPSK are store on each AP (as long as you "deploy" the configuration on it) so it won't affect site 2.

When using Cloud PPSK, in case of WAN outage, new authentication will fail, and currently authenticated devices will continue to communicate (according to our internal tests).

- Local PPSK is local to every single AP, meaning that you have to run a Delta Update after every single password change on every single AP.

- Question 2 is something some insight would be appreciated on my side too.
