New to proxmox, question about initial network config

[wammler]

I ran through the installer and got the system up and noticed it had no network connectivity. I looked at a few posts here and looked at /etc/network/interfaces and saw this:

auto lo
iface lo inet loopback

iface usb0 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.1.44/24
gateway 192.168.1.1
bridge-ports usb0
bridge-stp off
bridge-fd 0

iface eno1 inet manual

iface eno2 inet manual

iface eno3 inet manual

iface eno4 inet manual

I changed the bridge from "usb0" to eno3 in the interfaces file and now I have connectivity (my machine has 2 NICs on eno3/4). I believe usb0 is something related to USB devices attached to the system, but I am somewhat of a linux noob. Assuming that's the case I don't get why it would default the bridge to this one.

My question is, does proxmox use the usb0 interface intentionally? Will this break something later?

If eno3 is the NIC you want to use then bridge-ports eno3 is right.
