In ubuntu 18.04 or later, we have an application called netplan to manage our network. The configuration file is located in
/etc/netplan directory. In this tutorial, We will be using netplan to setup LACP bonding interfaces on UBuntu.
- Ubuntu 18.04 or Later
Before start we make sure that we will have no permission issue on the installation and configuration process.
To demonstrate how we can make LACP bonding interfaces, we will use this use case:
__________________ |______ | --------------------| eth0 | | 192.168.1.0/24 |______| ubuntu | --------------------| eth1 | server | |______| | |__________________|
Let’s assume we have a server with 2 interfaces named
eth1, connected to switch that is already configured with LACP bonding. The ip address assigned to the server is
192.168.1.10/24 with gateway
To make an LACP bonding, we have to install ifenslave first:
apt install ifenslave
bonding module on server by running this command:
To make the module activate on boot, open this file:
add this line:
To configure the network in our server, first open the configuration file:
In my server the file name is
50-cloud-init.yaml, maybe it is different in your case. Just open the yaml file located on
This is how the configuration is implemented to suits the use case we mention above:
network: ethernets: eth0: dhcp4: false eth1: dhcp4: false bonds: bond0: interfaces: [eth0, eth1] addresses: [192.168.1.10/24] gateway4: 192.168.1.1 parameters: mode: 802.3ad version: 2
We see on the on part
interfaces: [eth0, eth1], we will bonding
eth1 as one interface named
bond0. Note that we can add more interface as we need by put in the interface name to the array.
As we see that we use
mode: 802.3ad, it is a sign that we use LACP for bonding the interface.
After editing the file, use this command to activate the new configuration:
Thats it! Congratulation you just setup LACP bonding interfaces on Ubuntu 18.04!
