Run the below command to restart the network service. Run the below command to to load the bonding module. Options bond0 mode=balance-alb miimon=100 File name can be anything with вЂњ.confвЂќ extension. Next, create nf file to add the below line in /etc/modprobe.d/ directory to load the bonding module in to kernel. Now modify the network configuration file by adding the Master and Slave directives.ДЇor eth1 # vim /etc/sysconfig/network-scripts/ifcfg-eth1ДЇor eth2 # vim /etc/sysconfig/network-scripts/ifcfg-eth2 # vim /etc/sysconfig/network-scripts/ifcfg-bond0 Create a Bond Configuration FileДЇirst of all you need to create bond configuration file in /etc/sysconfig/network-scripts/ directory.

Channel bonding will work with the help of bonding driver in kernel. If one physical NIC is down or unplugged, it will automatically move resource to other NIC card. Channel bonding enables two or more network interfaces to act as one, simultaneously increasing the bandwidth and providing redundancy. Red Hat described bonding in documents as, Linux allows administrators to bind multiple network interfaces together into a single channel using the bonding kernel module and a special network interface called a channel bonding interface. The idea is pretty simple get higher data rates and as well as link failover. Use following command to view bond interface settings like bonding mode & slave interface.Bonding is nothing but Linux kernel feature that allows to aggregate multiple link interfaces (such as eth0, eth1) into a single virtual link such as bond0. Use вЂ ifconfigвЂ & вЂ ip addвЂ command to check bond interface along with its slave interfaces. ~]# systemctl restart rvice Step:4 Test & Verify bond interface.

SLAVE=yes Step:3 Restart the Network ServiceД«elow command will restart the network service and will bring above changes into the effect. Step:2 Edit the NIC interface filesДЇor ifcfg-enp0s3 ~]# vi /etc/sysconfig/network-scripts/ifcfg-enp0s3ДЇor ifcfg-enp0s8 ~]# cat /etc/sysconfig/network-scripts/ifcfg-enp0s8 In my example i am using вЂ mode=5вЂІ which is used to provide fault tolerance and load balancing.

Specify the IP address, Netmask & bonding modes as per your requirement. Create a bond interface file ( ifcfg-bond0) under the folder вЂњ network-scripts]# vi ifcfg-bond0
