I am running a fresh install of SCALE (TrueNAS-SCALE-21.02-ALPHA.1) and no matter what I do, all of my interfaces are down after a reboot.
I have a primary 10gbe intel interface with 1 vlan configures. DHCP is only on the VLAN to prevent multiple sources of information. I have to connect through IPMI, and then up both the interface and vlan, then run dhclient on the vlan. After do that the interfaces come up and the services start.
