4 port NIC with mixed IDs
-
I bought this card with 4 network ports on Amazon
https://www.amazon.it/gp/product/B083ST3TVZ.
After several attempts I identified the ports (starting from the top)- igp1
- igp0
- igp3
- igp4
I would have expected the ports to be sorted sequentially, top to bottom or bottom to top, not mixed together.
I wonder if it is the card that has problems and therefore must be returned, or if it is pfSense/FreeBSD that identifies the ports in this strange way. -
@darkcorner and there is no 2? yeah that is odd..
-
Similar for me on pfSense and Windows with Intel NICs. I got a Port 2...
1
0

I have an old server I have to setup proxmox on sometime today, been putting it off.. It has 2 4 port nics in it.. Will make sure to note order of ports.. I have been out of the server biz for quite some time but I don't recall them ever being out of order like that.. Sometimes they go in opposite direction than you might think.. But I don't recall them being out of order or skipping a number like he says where there is no 2..
I had a dual port nic in my old machine - but with only 2 its hard to tell if anything is off like being stated..
-
My first one like this was my first pfSense build and it took a bit to figure out why the WAN was getting an inside address. I thought it was a pfSense thing. Then I got an identical card for my PC and it did the same thing. Those are the only two I have seen do that and I have had many at work.
-
Wonder what is causing the naming.
First detected or lowest mac or ???My QOTOM-Q355G4 have messed up ports.
My newer 6-ports doesn't -
The port numbering order is entirely down the way FreeBSD parses the PCI tree.
You can force it to reorder using PCI Device Wiring but I don't recommend that. If you have to reinstall those settings will be lost and the ports would be re-ordered.

Best solution is prob just a label maker and label them hehe
-
On mine it is not the MAC, I checked. Just a guess, but maybe they crossed 2 wires. The 4 ports are really 4 NICs on 1 board. They would be found in order as the OS scans the bus.
As for the label maker idea, be sure it is a little one.
-
I bet they are not in order on the bus. Try running:
pciconf -lvThe NICs will almost certainly appear in the correct order for the PCI device locations. As seen by FreeBSD at least. It's not uncommon to see the BIOS pass different values for FreeBSD that it does for Windows.

For me with pfsense running in a VM under Proxmox, nic order is determined by the order they are defined in the VM definition created in Proxmox (I use nic pass through)
-
@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?

@johnpoz
What is happening would probably be shown bylspci -vand 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##*/}"; donebtw
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. -
@johnpoz
My error.- igp1
- igp0
- igp3
- igp2

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 -
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.
