Ubuntu 18.04.4 LTS

About 18 months ago I successfully bonded/teamed my two network adapters together, and I have no recollection of how I did it. I wanted to make some configuration changes to it today, but all the guides say to use /etc/network/interfaces, which has no mention of bond0. But bond0 is working no problem, and shows up in all the other correct places mentioned in the guides I find online for doing this, and the configuration persists through reboots no problem. Where else should I be looking for my configuration to make changes to it?

cat /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

-

ifconfig bond0

Netplan Update Doesn't appear to be netplan that I can tell:

/etc/netplan$ ls
01-network-manager-all.yam

/etc/netplan$ cat 01-network-manager-all.yaml
# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager

Update 2

ls -al /etc/network/interfaces.d
total 8
drwxr-xr-x 2 root root 4096 Apr 27  2018 .

  • IIRC Network Manager calls it teaming. Is there any mention of team in NM configuration? Anything in netplan configuration?

  • Where is the NM configuraiton? Google says maybe /etc/NetworkManager/NetworkManager.conf? There is no interface config in this file.

  • Maybe you've configured it by using netplan?

  • I don't think so. /etc/netplan$ ls 01-network-manager-all.yaml peter@wicks-server:/etc/netplan$ cat 01-network-manager-all.yaml # Let NetworkManager manage all devices on this system network: version: 2 renderer: NetworkManager

  • Edit your question and show me ls -al /etc/network/interfaces.d and ls -al /etc/netplan, and show me a screenshot of the nm-connection-editor window.

From the comments...

In terminal, check out nm-connection-editor or nmtui. You'll find bond0 there.

  • Ok, so I think nm-connection-editor is something I want... except that I can't figure out how to use it.
