IFENSLAVE(8) BSD System Manager's Manual IFENSLAVE(8)
NAME
ifenslave — Attach and detach slave network devices to a bonding device.
SYNOPSIS
ifenslave [-acdfhuvV] [--all-interfaces] [--change-active] [--detach] [--force] [--help] [--usage] [--verbose]
[--version] master slave ...
DESCRIPTION
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 "trunk‐
ing" techniques used in switches.
The kernel must have support for bonding devices for ifenslave to be useful.
OPTIONS
-a, --all-interfaces
Show information about all interfaces.
-c, --change-active
Change active slave.
-d, --detach
Removes slave interfaces from the bonding device.
-f, --force
Force actions to be taken if one of the specified interfaces appears not to belong to an Ethernet
device.
-h, --help
Display a help message and exit.
-u, --usage
Show usage information and exit.
-v, --verbose
Print warning and debug messages.
-V, --version
Show version information and exit.
If not options are given, the default action will be to enslave interfaces.
EXAMPLE
The following example shows how to setup a bonding device and enslave two real Ethernet devices to it:
# modprobe bonding
# ifconfig bond0 192.168.0.1 netmask 255.255.0.0
# ifenslave bond0 eth0 eth1
