[SOLVED] Help Identifying network ports

[greptrig]

Maybe I’m missing something that makes this a lot easier to manage.

My question is, I have several network segments all running through my proxmox. Is there any easy way to track down ports when assigning them?
en01
1f0
1f1
2f0
2f1
Continues to 8f1
My problem is I have no way to tell my 10g Sfp or rj45 apart all intel cards accept en0 service port. It shows up as something different.

I can’t even see the default MAC address or I could map it from the BIOS.

Waiting watching the rack reboot just to test network ports and reboot again one cable at a time by process of elimination.

There has to be a better way!

Hi @greptrig

There are two commands that should get you what you need:

ip Command

If you run ip a from the command line, it will match your interface names to their MAC Addresses.

lshw Command

The lshw the command will need to be installed, but it will give you much more information about each NIC. For example, it will give you the MAC address, model, speed and bus information. We install this by default on any PVE hosts we set up.

Hi greptrig, you can also use command dmesg -T | grep eno and dmesg -T | grep nic to cross reference with ip a, that for finding the MAC address belongs with NIC name are useful.
