What is Bond configuration?

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. The idea is pretty simple get higher data rates and as well as link failover. Channel bonding will work with the help of bonding driver in kernel.

How does network bonding work?

Network bonding is a process of combing or joining two or more network interfaces together into a single interface. Network bonding offers performance improvements and redundancy by increasing the network throughput and bandwidth. If one interface is down or unplugged the other one will work.

What is the difference between teaming and bonding?

Bonding:- Bonding refers to create a bond or aggregation of two or more links into one in order to provide failover and redundancy to the network. Teaming:- Is a new way implementation of bonding and provides a separate driver.

What is bonding interfaces in Linux?

Network Interface Bonding is a mechanism used in Linux servers which consists of binding more physical network interfaces in order to provide more bandwidth than a single interface can provide or provide link redundancy in case of a cable failure.

How do I check my bond status?

Verify the bonding status by using the command cat /proc/net/bonding/bond0 . Check the LACP parameters from the actor (server self-configuration) device and confirm that they are correct as per the local configuration. Verify link failure counts and MII status and determine if any links are flapping.

How to configure network bonding on RHEL 7?

Deactivate and reactivate bond0 with the ifdown and ifup commands: Step7. Check the status of bond0 and the slaves with the ip command. It should also show the assigned IP. Step8.

How does bonding work in Red Hat Linux?

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.

Where do I find bonding configuration in Linux?

Linux and other platforms stores network configuration by default in /etc/sysconfig/network-scripts/ directory. First, we need to create a bond0 config file as follows, change the values like IP Address as per your environment. Save and close the file. Edit both the configuration files as follows for eth0 and eth1 interfaces.

What does network bonding mean in CentOS 6?

Network Bonding is the aggregation of multiple lan cards(eth0 & eth1) into a single interface called bond interface. Network Bonding is a kernel feature and also known as NIC teaming. Bonding is generally required to provide high availability and load balancing services.
