## 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 sim‐
       ple 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
