How can I create a bond interface in Ubuntu 18.04?
Solution 1:
I installed Ubuntu Server and surprising enough it asked me if I wanted to to setup bonding.
This is the yaml file that was setup:
Location: /etc/netplan/
File Name: 50-cloud-init.yaml
File Structure:
# This file is generated from information provided by
# the datasource. Changes to it will not persist across an instance.
# To disablecloud-init's network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
bonds:
bond0:
addresses: []
interfaces:
- enp5s4
- enp5s9
- enp64s0
parameters:
lacp-rate: fast
mode: 802.3ad
transmit-hash-policy: layer2
ethernets:
enp5s4:
addresses: []
dhcp4: false
dhcp6: false
enp5s9:
addresses: []
dhcp4: false
dhcp6: false
enp64s0:
addresses: []
dhcp4: false
dhcp6: false
version: 2
I will update this as I learn more about the newer style of networking configuration in Ubuntu.
UPDATE
To change this to be static address do the following:
sudo mv /etc/netplan/50-cloud-init.yaml /etc/netplan/50-cloud-init.old
!Note! Your default *.yaml file name may be different.
sudo touch /etc/netplan/my-network-file.yaml
!Note! You can name your config file whatever you want just make sure it ends with .yaml
sudo nano /etc/netplan/my-network-file.yaml
In this file (my-network-file.yaml) copy from above and append the following changes:
network:
bonds:
bond0:
addresses: [192.168.0.8/24]
gateway4: 192.168.0.1
nameservers:
addresses: [8.8.8.8,8.8.4.4]
interfaces:
- enp5s4
- enp5s9
- enp64s0
Make sure you change the ip addresses to reflect your network. After this, I just rebooted the machine and my new network config was loaded and working.
You can alternatively use:
sudo netplan apply
This should apply the new config without a need for a reboot.
Side Note You may want to observe spacing and not use tabs as this may cause issues with your config file.
If you're unsure of your network interfaces you can do one of the following
lshw -class network
or
ip link show
Hope this helps!
