Step 1 – Login using SSH

Step 2 – Install the ifenslave dependency

• sudo apt-get install ifenslave

Step 3: Load bonding kernel module

Before you can configure the network cards you need to ensure that the kernel module called bonding is present and loaded.

• sudo lsmod | grep bonding

If the module is not loaded. Use the following command to load it

• sudo modprobe bonding

To ensure that the bonding module is loaded during boot time change file the following file

• sudo nano /etc/modules

Add the following line:

• bonding

Step 4 – find the active network interface

• clear && echo $(ip -o -4 route get 8.8.8.8 | sed -nr ‘s/.*dev ([^\ ]+).*/\1/p’)

Step 5 – Configure the network interface

The output of step 4 is the network interface which is active at the moment. You should use that name for the bond. In our case this is eno1 and the second interface eno2

• # This is the network config written by ‘subiquity’
• network:
• bonds:
• bond0:
• addresses:
• – 89.47.232.155/27
• gateway4: XX.XX.XX.XX
• interfaces:
• – eno1
• – eno2
• nameservers:
• addresses:
• – 8.8.8.8
• search: []
• parameters:
• lacp-rate: fast
• mode: 802.3ad
• transmit-hash-policy: layer3+4
• mii-monitor-interval: 100
• ethernets:
• eno1: {}
• eno2: {}
• version: 2

Apply the changes

• sudo netplan apply

Step 6 – Reboot

• reboot
