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 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
