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 bond-
     ing 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.

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 no 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 de-
     vices to it:

     # modprobe bonding
     # ifconfig bond0 192.168.0.1 netmask 255.255.0.0
     # ifenslave bond0 eth0 eth1
