ifenslave: Attach and detach slave network devices to a bonding device.

NAME

ifenslave - Attach and detach slave network devices to a bonding device.

SYNOPSIS

[-acdfhuvV ] [--all-interfaces ] [--change-active ] [--detach ] [--force ] [--help ] [--usage ] [--verbose ] [--version ] master slave ...

DESCRIPTION

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 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
