How to set up LACP bonding with Netplan
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
