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
