What happens to network settings after motherboard replacement?

[Thomymaster]

Hi


I want to change my mainboard for a newer one (due to more power saving, CPU-power an RAM).

I have configured my ethernet settings for the old mainboard using the onboard NIC.

What happens now if i change the mainboard:

-do i have to reconfigure the NIC again (due to the new NIC it is named em1 instead of em0)
-is no change neccessary and the config remains (is the first network adapter on a mainboard em0, the second em1 and so on. "The first" could mean according to PCI device number or MAC address)

?

Cheers Thomy

It depends. Worst-case, you'll have to reconfigure it from the local shell, which takes only a few moments.

OK, it depends on what? :)

Depends on whether it works!

If they are both em0, it'll probably work as it. Anything else, probably not. But, as Ericloewe said, it only takes a minute or two, to fix it via option #1 on the Console Setup Menu.

I changed my hardware a couple of years ago. The only issue I had to fix was a NIC issue like this.

This isn't Windows, Linux, or Solaris, where they wire in varying levels of information about the specific card and PCI slot, which seems to be what you've experienced in the past. If the network controllers are of the same type, they just magically work. If not, you need to do a minimal amount of reconfiguration to tell FreeNAS to use the new card. For example, older Intel controllers are typically "em0" while newer ones may be "igb0", and if you make such a hardware transition, yes, you need to reconfigure that. But if you had an old Intel Pro/1000 PT and switched to Intel Pro/1000 CT, both of which are em, that's totally transparent.

Confirmed. Just two days ago, I swapped an older AM3 motherboard for a shiny new X10 mobo, and as previously alluded to, all I had to do was reconfigure the NIC quick in the shell, and that was that. Everything else worked perfectly.

OK, thanks
