These steps must be performed on each server, using the appropriate IP and MAC addresses..

In this example, we show the content of the 3 configuration files in the /etc/sysconfig/network-scripts

directory required to create the bonded interface. The ifcfg-eth# files may already exist, but the

ifcfgbond0 file probably does not exist.

1. Change directory:

cd /etc/sysconfig/network-scripts

2. Create ifcfg-bond0 and add the IP address and other network addresses according to your

environment as well as the other fields listed here, for example:

DEVICE=bond0

IPADDR=16.89.84.247

NETMASK=255.255.255.128

NETWORK=16.89.84.128

BROADCAST=16.89.84.255

ONBOOT=yes

BOOTPROTO=none

USERCTL=no

BONDING_OPTS='miimon=100 mode=1'

NOTE: There is no space between the key-value pair variables. For example, there must be

no space between DEVICE (key) and bond0 (value) pair.

3. Edit the ifcfg-ethN file to contain the following content. Remove existing entries, if any,

except for “DEVICE” and “HWADDR”. Make sure that the HWADDR field matches the

specific MAC address for the card, do not use the value listed here. Following is an example

for ifcfg-eth2:

DEVICE=eth2

USERCTL=no

ONBOOT=yes

MASTER=bond0

SLAVE=yes

BOOTPROTO=none

HWADDR=00:14:C2:C0:44:C5

4. Edit the ifcfg-ethN file to contain the following content. Remove existing entries, if any,

except for “DEVICE” and “HWADDR”. Make sure that the HWADDR field matches the

specific MAC address for the card, do not use the value listed here. Following is an example

for ifcfg-eth3:

DEVICE=eth3

USERCTL=no

ONBOOT=yes

MASTER=bond0

SLAVE=yes

BOOTPROTO=none

HWADDR=00:14:C2:C0:44:C4

5. Edit /etc/modprobe.conf to add the following lines (the second and third lines shown here

must be in one line):

alias bond0 bonding

install bond0 /sbin/modprobe tg3; /sbin/modprobe e1000;

/sbin/modprobe –-ignore-install bonding –o bond0

NOTE: You may see an error while shutting down bond0, since it previously didn’t exist.

For example:

/etc/sysconfig/network-scripts/ifdown-eth: line 101:

/sys/class/net/bond0/bonding/slaves: No such file or
