The ''ifenslave'' program is used to set up bonding for network devices. This must be used in conjunction with support for bonding in the Linux kernel.

Program syntax is ''ifenslave [options] master slave [slave..]''.

Options include:

  * **-a** - show information about all devices
  * **-c** - change active state
  * **-d** - remove slave interface from the bonding device
  * **-f** - force action, even if one of the interfaces doesn't look like an Ethernet device
  * **-v** - verbose output

An example of creating a bonding device, using two interfaces, where ''eth0'' is the master and ''eth1'' is the slave:

<code>
ifenslave eth0 eth1
</code>

The new device name is ''bond0'', and can be set as normal using ''ifconfig'', ''ip'', ''ifup'', etc.

Check the bonding interface:

<code>
cat /proc/net/bonding/bond0
</code>
