Bonding technology provides an additional benefit in that with multiple network interfaces effectively supporting the same communications channel, a fault within a single network interface in a bonded group does not stop communication. For example, you have a bonded setup with four network interfaces providing a single interface channel between two DRBD servers. If one network interface fails, communication can continue on the other three without interruption, although at a lower speed.<\/p>\n

I will give an example for bonding. I will use 4 ethernet interface for 2 different connection areas which are public and private connections. You can use these connections for cluster systems.<\/p>\n

You have to do below processes with root user. <\/p>\n

Disable Network Manager<\/strong><\/p>\n

\nservice NetworkManager stop
\nchkconfig NetworkManager off\n<\/p><\/blockquote>\n

Create bond0 and bond1 Interface<\/strong><\/p>\n

\nvi \/etc\/sysconfig\/network-scripts\/ifcfg-bond0<\/p>\n

\nDEVICE=”bond0″
\nBROADCAST=”192.168.10.255″
\nGATEWAY=”192.168.10.1″
\nIPADDR=”192.168.10.10″
\nNETMASK=”255.255.255.0″
\nONBOOT=”yes”
\nUSERCTL=no
\nBONDING_OPTS=”mode=0 miimon=100 downdelay=300 updelay=300″\n<\/p><\/blockquote>\n

vi \/etc\/sysconfig\/network-scripts\/ifcfg-bond1<\/p>\n

\nDEVICE=”bond1″
\nBROADCAST=”192.168.10.255″
\nGATEWAY=”192.168.10.1″
\nIPADDR=”192.168.10.12″
\nNETMASK=”255.255.255.0″
\nONBOOT=”yes”
\nUSERCTL=no
\nBONDING_OPTS=”mode=0 miimon=100 downdelay=300 updelay=300″\n<\/p><\/blockquote>\n<\/blockquote>\n

You can then configure additional parameters for the kernel module. Typical parameters are the mode option and the miimon option.<\/p>\n

The mode option specifies how the network interfaces are used. The default setting is 0, which means that each network interface is used in a round-robin fashion (this supports aggregation and fault tolerance). Using setting 1 sets the bonding mode to active-backup. This means that only one network interface is used as a time, but that the link automatically fails over to a new interface if the primary interface fails. This settings only supports fault-tolerance.<\/p>\n

The miimon option enables the MII link monitoring. A positive value greater than zero indicates the monitoring frequency in milliseconds for checking each slave network interface that is configured as part of the bonded interface. A typical value is 100.

\nConfigure eth0 and eth1 Interfaces for bond0 (Add or Change Below Texts)<\/strong><\/p>\n

\nvi \/etc\/sysconfig\/network-scripts\/ifcfg-eth0<\/p>\n

\nDEVICE=eth0
\nBOOTPROTO=none
\nMASTER=bond0
\nHWADDR=00:01:02:03:04:05
\nONBOOT=yes
\nSLAVE=yes
\nUSERCTL=no\n<\/p><\/blockquote>\n

vi \/etc\/sysconfig\/network-scripts\/ifcfg-eth1<\/p>\n

\nDEVICE=eth1
\nBOOTPROTO=none
\nMASTER=bond0
\nHWADDR=00:01:02:03:04:06
\nONBOOT=yes
\nSLAVE=yes
\nUSERCTL=no\n<\/p><\/blockquote>\n<\/blockquote>\n

Change eth2 and eth3 Interfaces for bond1<\/strong><\/p>\n

\nvi \/etc\/sysconfig\/network-scripts\/ifcfg-eth2<\/p>\n

\nDEVICE=eth2
\nBOOTPROTO=none
\nMASTER=bond1
\nHWADDR=00:01:02:03:04:50
\nONBOOT=yes
\nSLAVE=yes
\nUSERCTL=no\n<\/p><\/blockquote>\n

vi \/etc\/sysconfig\/network-scripts\/ifcfg-eth3<\/p>\n

\nDEVICE=eth3
\nBOOTPROTO=none
\nMASTER=bond1
\nHWADDR=00:01:02:03:04:60
\nONBOOT=yes
\nSLAVE=yes
\nUSERCTL=no\n<\/p><\/blockquote>\n<\/blockquote>\n

Configure Modprobe<\/strong><\/p>\n

\nvi \/etc\/modprobe.d\/bonding.conf<\/p>\n

\nalias eth0 e1000e
\nalias eth1 e1000e
\nalias eth2 e1000e
\nalias eth3 e1000e
\nalias bond0 bonding
\nalias bond1 bonding\n<\/p><\/blockquote>\n<\/blockquote>\n

Network Restart<\/strong><\/p>\n

\nmodprobe bonding
\nservice network restart<\/p>\n

Note :<\/strong> If you do not see below screen, you can reboot system.\n<\/p><\/blockquote>\n

\"\"<\/p>\n

Finally, You can use these configurations on Oracle Linux 6.x, Redhat Linux 6.x, Centos 6.x.<\/p>\n
