3 For high availability, edit the /etc/modprobe.conf file and set the option for link monitoring.
The default value for
miimon is 0 , which disables link monitoring. Change the value to
100 milliseconds initially, and adjust it as needed to improve performance. Type:
options bonding miimon=100 mode=1

In the /etc/sysconfig/network-scripts/ directory, create or edit the ifcfg-bond0 configuration file.
For example, using sample network parameters, the file would appear as follows:
DEVICE=bond0
IPADDR=192.168.0.1
NETMASK=255.255.255.0
NETWORK=192.168.0.0
BROADCAST=192.168.0.255
ONBOOT=yes
BOOTPROTO=none
USERCTL=no
The entries for NETMASK , NETWORK , and BROADCAST are optional.
DEVICE=bondn is the required name for the bond, where n specifies the bond number.
IPADDR is the private IP address.
To use bond0 as a virtual device, you must specify which devices will be bonded as slaves.
5 For each device that is a bond member, perform the following steps:
a In the directory /etc/sysconfig/network-scripts/ , edit the ifcfg-eth n file, containing the following
lines:
DEVICE=ethn
HWADDR=<MAC ADDRESS>
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
MASTER=bond0
SLAVE=yes
BOOTPROTO=none
b Ty p e service network restart and ignore any warnings.
6 On each node , type ifconfig to verify that the private interface is functioning.
The private IP address for the node should be assigned to the private interface bond0.
7 When the private IP addresses are set up on every node, ping each IP address from one node to ensure
that the private network is functioning.
8 Ty p e ssh <private IP> to connect to each node and verify that the private network and ssh are
functioning correctly.
