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 bond-
     ing 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-bal-
     ancing, identical to "channel bonding" or "trunking" techniques used in
     switches.
     The kernel must have support for bonding devices for ifenslave to be use-
     ful.
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 inter-
     faces.
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
