## 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 "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 devices
     to it:

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