Overview
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.
Examples
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
