IFENSLAVE(8) System Manager's Manual IFENSLAVE(8)


ifenslaveAttach and detach slave network devices to a bonding device.


ifenslave [-acdfhuvV] [--all-interfaces] [--change-active] [--detach] [--force] [--help] [--usage] [--verbose] [--version] master slave ...


ifenslave is a tool to attach and detach slave network devices to a bonding device. A bonding device will act like a normal Ethernet network device to the kernel, but will send out the packets via the slave devices using a simple round-robin scheduler. This allows for simple load-balancing, identical to "channel bonding" or "trunking" techniques used in switches.

The kernel must have support for bonding devices for ifenslave to be useful.


Show information about all interfaces.
Change active slave.
Removes slave interfaces from the bonding device.
Force actions to be taken if one of the specified interfaces appears not to belong to an Ethernet device.
Display a help message and exit.
Show usage information and exit.
Print warning and debug messages.
Show version information and exit.

If no options are given, the default action will be to enslave interfaces.


The following example shows how to setup a bonding device and enslave two real Ethernet devices to it:

# modprobe bonding
# ifconfig bond0 netmask
# ifenslave bond0 eth0 eth1
