Hi ,
https://documentation.meraki.com/MX/Access_Control_and_Splash_Page/MX_Access_Policies_(802.1X)
I think this page is lacking a lot of crucial information.
1- What happens if you put multiple RADIUS servers ? Is it round-robin ?
2- How is the MX made aware of RADIUS failures / timeout ? Will it go to the next RADIUS server ?
3- Is there a fallback mecanism ? If RADIUS #1 is unreachable and it going to RADIUS #2 , Will it comeback to RADIUS #1 or only switchback if RADIUS #2 comes unreachable ?
I do know most of these answers , but I'm pretty sure that would help a lot of people.
