The steps for setting the Linux bonding mode are as follows. Note that these are
example commands. The actual commands may be different depending on the
system configuration.

% modprobe bonding mode=1 miimon=100 updelay=50000
primary=eth16

% ifconfig bond0 25.145.1.199 netmask 255.255.255.0
broadcast 25.145.1.255 up
3.
% ifenslave bond0 eth15 eth16
Type the following command to bring down the bond:
% ifconfig bond0 down
NOTE:
These commands and steps have been tested under RHEL5. Other Linux
