IFENSLAVE(8) 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 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

--all-interfaces
Show information about all interfaces.
--change-active
Change active slave.
--detach
Removes slave interfaces from the bonding device.
--force
Force actions to be taken if one of the specified interfaces appears not to belong to an Ethernet device.
--help
Display a help message and exit.
--usage
Show usage information and exit.
--verbose
Print warning and debug messages.
--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
