The mystery of the disappearing interfaces

Hi All,

I've installed 19.7 on a Fujitsu rx100 S7 server, with an Intel dual 10G SFP+ NIC, an Intel single 10GbE ethernet card and two intel 1GbE nics built in to the motherboard.

After installation and a reboot, I ran the interface assignment from the CLI and configured the cards as follows:

1GbE onboard - em0 - Not connected
1GbE onboard - em1 - WAN
10Gb SFP+ -  ix0 - LAN
10Gb SFP+ -  ix1 - DMZ
10GbE - ix2 - PAV

Once done, I rebooted and when it came back up, one of the interfaces had disappeared and the install been rearranged to:

1GbE onboard - em0 - Not connected
1GbE onboard - em1 - WAN
10Gb SFP+ -  ix0 - LAN
10Gb SFP+ -  ix1 - DMZ  [Disappeared]
10GbE - ix1 - PAV - [Now relabled from ix2]

First thought was that I'd run it live and they'd disappeared after the reboot but when I checked syslog.log, ix2 was mentioned so it must have present after the install, but disappeared after the reboot.

I'm from a Linux background so don't mind the command line but this is my first time debugging BSD so is there any advice anyone can give for  tracking down what's happened/
