What happens to a Leaf if you lose all APIC's and the Leaf reboots?

Hello all,

 

I'm curious what would happen if you lost all the APIC's in your cluster, and then you had a Leaf that rebooted for some reason (perhaps it temporarily lost power or whatever).

 

Would that Leaf retain its configuration on a disk or flash memory somewhere in its hardware, or do Leafs have to ask the APIC's for their configuration each time they boot up?

 

If you lost all the APIC's I would imagine traffic in the fabric would be uninterrupted, but I'm curious if a Leaf (or even a Spine for that matter) rebooted AFTER you had lost all APICs in the cluster. Would that mean you would lose the config on that Leaf/Spine as well?

The configuration is preserved.

setup-clean-config.sh followed by a reload are the commands which clears the configuration from a leaf/spine switch.
