4 port NIC with mixed IDs

johnpoz

@patch well got proxmox running - and its showing the interfaces freaking odd, ie get the 1-4, but then 49-52

Haven't setup any vms yet just got the thing booted.. Old DL360 gen9..

Interesting. I'd check the PCI locations there too. If they're not the same card perhaps one set of NICs is behind a bridge so appears on a different bus?

What is happening would probably be shown by

lspci -v

and if you have set up pass through

for d in /sys/kernel/iommu_groups/*/devices/*; do n=${d#*/iommu_groups/*}; n=${n%%/*}; printf 'IOMMU group %s ' "$n"; lspci -nns "${d##*/}"; done

btw
When you create your VM I find it easiest to assign no NIC
then go to pve -> VM -> Hardware
and add nic in the order you want them to apear in pfsense ie WAN, LAN, Op1 etc
In pfsense then they will be given sequential numbers in that order.

My error.

igp1
igp0
igp3
igp2

I bet they are not in order on the bus. Try running: pciconf -lv

Even so I would have expected them to be in order.

Best solution is prob just a label maker and label them hehe

I had thought of that too.
However, if the numbering derives from FreeBSD the important thing is that this does not change at each restart because otherwise it would skip the assignment of the networks and therefore of the connected cables.

@patch
Is there lspci on FreeBSD / pfSense?
I can't even find a package, I also tried with pciutils.

No
It is a linux command relevant to Proxmox not pfsense install

stephenw10

pciconf is the FreeBSD equivalent for most functions.

You can see though how the ports are numbered in the order they are seen on the bus:

igb0@pci0:5:0:0:
igb1@pci0:5:0:1:
igb2@pci0:6:0:0:
igb3@pci0:6:0:1:

There's nothing you can do to change that.

Interpreting the pciconf data, I believe the problem is due to the card having two buses for two NICs each.
Therefore, the double sequence igp1-0 and igp3-2 is explained.
OK. I'll put a label indicating the ports ID.
Thanks everyone.
