Installation

sudo apt-get install ifenslave

Interface Configuration

Step 1: Ensure kernel support

Before Ubuntu can configure your network cards into a NIC bond, you need to ensure that the correct kernel module bonding is present, and loaded at boot time.
Edit your /etc/modules configuration:

sudo vi /etc/modules

Ensure that the bonding module is loaded:

# /etc/modules: kernel modules to load at boot time.## This file contains the names of kernel modules that should be loaded# at boot time, one per line. Lines beginning with "#" are ignored.looplprtcbonding

Step 2: Configure network interfaces

Ensure that your network is brought down:

sudo stop networking

Then load the bonding kernel module:

sudo modprobe bonding

Now you are ready to configure your NICs.
Edit your interfaces configuration:

 sudo vi /etc/network/interfaces

For example, to combine eth0 and eth1 as slaves to the bonding interface bond0 using a simple active-backup setup, with eth0 being the primary interface:

# This file describes the network interfaces available on your system# and how to activate them. For more information, see interfaces(5).# The loopback network interfaceauto loiface lo inet loopback# The primary network interface#auto eth0#iface eth0 inet dhcp# This is an autoconfigured IPv6 interface#iface eth0 inet6 auto# eth0 is manually configured, and slave to the "bond0" bonded NICauto eth0iface eth0 inet manual    bond-master bond0    bond-primary eth0# eth1 ditto, thus creating a 2-link bond.auto eth1iface eth1 inet manual    bond-master bond0# bond0 is the bonding NIC and can be used like any other normal NIC.# bond0 is configured using static network information.auto bond0iface bond0 inet dhcp   # address 192.168.1.10   # gateway 192.168.1.1   # netmask 255.255.255.0    bond-mode active-backup    bond-miimon 100    bond-slaves none

Next Start/Restart network service to take effect the changes:

/etc/init.d/networking start

Bring up bond0:

ifup bond0

Checking the bonding interface

Link information is available under /proc/net/bonding/. To check bond0 for example:
