There are, essentially, two methods for configuring bonding:

initialization scripts: initscripts or sysconfig. Recent versions of
these packages have support for bonding, while older versions do not.

3.4 Configuring Bonding Manually via Sysfs
------------------------------------------
5. Querying Bonding Configuration
Starting with version 3.0, Channel Bonding may be configured
via the sysfs interface. This interface allows dynamic configuration
of all bonds in the system without unloading the module. It also
allows for adding and removing bonds at runtime. Ifenslave is no
longer required, though it is still supported.
Use of the sysfs interface allows you to use multiple bonds
with different configurations without having to reload the module.
It also allows you to use multiple, differently configured bonds when
bonding is compiled into the kernel.
You must have the sysfs filesystem mounted to configure
bonding this way. The examples in this document assume that you
are using the standard mount point for sysfs, e.g. /sys. If your
sysfs filesystem is mounted elsewhere, you will need to adjust the
example paths accordingly.
Creating and Destroying Bonds
-----------------------------
To add a new bond foo:
# echo +foo > /sys/class/net/bonding_masters
To remove an existing bond bar:
# echo -bar > /sys/class/net/bonding_masters
To show all existing bonds:
# cat /sys/class/net/bonding_masters
NOTE: due to 4K size limitation of sysfs files, this list may be
truncated if you have more than a few hundred bonds. This is unlikely
to occur under normal operating conditions.
Adding and Removing Slaves
--------------------------
Interfaces may be enslaved to a bond using the file
/sys/class/net/<bond>/bonding/slaves. The semantics for this file
are the same as for the bonding_masters file.
To enslave interface eth0 to bond bond0:
# ifconfig bond0 up
# echo +eth0 > /sys/class/net/bond0/bonding/slaves
To free slave eth0 from bond bond0:
# echo -eth0 > /sys/class/net/bond0/bonding/slaves
NOTE: The bond must be up before slaves can be added. All
slaves are freed when the interface is brought down.
When an interface is enslaved to a bond, symlinks between the
two are created in the sysfs filesystem. In this case, you would get
/sys/class/net/bond0/slave_eth0 pointing to /sys/class/net/eth0, and
/sys/class/net/eth0/master pointing to /sys/class/net/bond0.
This means that you can tell quickly whether or not an
interface is enslaved by looking for the master symlink. Thus:
# echo -eth0 > /sys/class/net/eth0/master/bonding/slaves
will free eth0 from whatever bond it is enslaved to, regardless of
the name of the bond interface.
Changing a Bond's Configuration
-------------------------------
Each bond may be configured individually by manipulating the
files located in /sys/class/net/<bond name>/bonding
The names of these files correspond directly with the command-
line parameters described elsewhere in in this file, and, with the
exception of arp_ip_target, they accept the same values. To see the
current setting, simply cat the appropriate file.
A few examples will be given here; for specific usage
guidelines for each parameter, see the appropriate section in this
document.
To configure bond0 for balance-alb mode:
# ifconfig bond0 down
# echo 6 > /sys/class/net/bond0/bonding/mode
- or -
# echo balance-alb > /sys/class/net/bond0/bonding/mode
NOTE: The bond interface must be down before the mode can be
changed.
To enable MII monitoring on bond0 with a 1 second interval:
# echo 1000 > /sys/class/net/bond0/bonding/miimon
NOTE: If ARP monitoring is enabled, it will disabled when MII
monitoring is enabled, and vice-versa.
To add ARP targets:
# echo +192.168.0.100 > /sys/class/net/bond0/bonding/arp_ip_target
# echo +192.168.0.101 > /sys/class/net/bond0/bonding/arp_ip_target
NOTE: up to 10 target addresses may be specified.
To remove an ARP target:
# echo -192.168.0.100 > /sys/class/net/bond0/bonding/arp_ip_target
Example Configuration
---------------------
We begin with the same example that is shown in section 3.3,
executed with sysfs, and without using ifenslave.
To make a simple bond of two e100 devices (presumed to be eth0
and eth1), and have it persist across reboots, edit the appropriate
file (/etc/init.d/boot.local or /etc/rc.d/rc.local), and add the
following:
modprobe bonding
modprobe e100
echo balance-alb > /sys/class/net/bond0/bonding/mode
ifconfig bond0 192.168.1.1 netmask 255.255.255.0 up
echo 100 > /sys/class/net/bond0/bonding/miimon
echo +eth0 > /sys/class/net/bond0/bonding/slaves
echo +eth1 > /sys/class/net/bond0/bonding/slaves
To add a second bond, with two e1000 interfaces in
active-backup mode, using ARP monitoring, add the following lines to
your init script:
modprobe e1000
echo +bond1 > /sys/class/net/bonding_masters
echo active-backup > /sys/class/net/bond1/bonding/mode
ifconfig bond1 192.168.2.1 netmask 255.255.255.0 up
echo +192.168.2.100 /sys/class/net/bond1/bonding/arp_ip_target
echo 2000 > /sys/class/net/bond1/bonding/arp_interval

---help---
APM is a BIOS specification for saving power using several different
techniques. This is mostly useful for battery powered systems with
APM compliant BIOSes. If you say Y here, the system time will be
reset after a RESUME operation, the /proc/apm device will provide
battery status information, and user-space programs will receive
notification of APM "events" (e.g. battery status change).
In order to use APM, you will need supporting software. For location
and more information, read <file:Documentation/pm.txt> and the
Battery Powered Linux mini-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.
This driver does not spin down disk drives (see the hdparm(8)
manpage ("man 8 hdparm") for that), and it doesn't turn off
VESA-compliant "green" monitors.
Generally, if you don't have a battery in your machine, there isn't
much point in using this driver and you should say N. If you get
random kernel OOPSes or reboots that don't seem to be related to
anything, try disabling/enabling this option (or disabling/enabling
APM in your BIOS).
