Do interface dev numbers need to match?

[Andyrue]

I understand I can use different hardware, I just need to match the number and order of the interfaces.  I assume it's ok to have a greater number of NICs in one box as long as they're not assigned? Also, is the order that matters what's listed in the GUI, or are we talking about the order of the device interfaces, em0, em1, etc?

For instance, I have the following setup.

Box 1               
WAN1 - em1
LAN - em0
WAN2 - em2
SYNC - em3

Box 2
WAN1 - em5
LAN - em2
WAN2 - em4
SYNC - em3

The order the interfaces appear in the assign interfaces window are the same, but the device numbers are in a different order.  Do I need to switch things around so the ems match?

You're OK. So long as the order of assignment is the same it doesn't matter how they line up physically.

Great.  Thanks!
