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
