@Eng.AD27 if the Meraki MX64's are configured in HA and this is functioning correctly, then a down interface (link failure) on the current active firewall would cause the secondary (spare) firewall to become active and takeover.

Dear @Rob Ingram
this clear for Uplinks
what about for Downlink if that fails
do you have any idea ?

@Eng.AD27 any interface should cause the firewall to failover.
