Network Interface name correction

[Raimund Sacherer]

Hello, 

not sure if this is the right list to ask about it but here it goes. We have one firewall (out of a cluster) in a very remote area and it displays erratic behaviour. On reboot, sometimes it initialises network port 0 correctly and sometimes it does not. 

I firmly believe it has to do with the KVM port being activate on port 0 and I had lot's of troubles with it (working/not working) so it's a gamble if port 0 can be initialised on reboot or not. And more often then not it doesn't come up correctly. 

When it does not work I get this in the boot log: 

em0: <Intel(R) PRO/1000 Network Connection 7.4.2> port 0xf060-0xf07f mem 0xf7c00000-0xf7c1ffff,0xf7c34000-0xf7c34fff irq 20 at device 25.0 on pci0 
em0: Using an MSI interrupt 
em0: Setup of Shared code failed 
device_attach: em0 attach returned 6 



My real problem is that once this happens that the port which should be em1 will now be em0 and then all my port assignments don't work anymore. In anticipation of this possible error I configured the VLANs on the switches accordingly so at least I can get access to the firewall and can work on it, but I do not know how I can force e.g. that MAC XX always is em1 (or em2, em3) regardless of what the BIOS or the boot process think it should be. 


Thank you, 
Best
