NIC Bonding/Teaming in RHEL6
NIC [network interface card] bonding is a term used to describe a way to increase available bandwidth. Bonding is nothing but Linux kernel feature[aka BONDING] that allows to aggregate multiple like interfaces (such as eth0, eth1, eth2 etc) into a single virtual link. This is done to get higher data rates and as well as link failover. NIC bonding may also be called as NIC Teaming. Here we will create a bond called bond0 , number of ether-net's used are two [ eth0 and eth1 ]. Step 1: Create a bond0 file==> # vim /etc/sysconfig/network-scripts/ifcfg-bond0 Append the file with below information and save the file==> DEVICE=bond0 IPADDR=192.168.57.150 NETMASK=255.255.255.0 USERCTL=no BOOTPROTO=none ONBOOT=yes Note: IP and Netmask needs to be replaced as per your network configuration. Step 2: Edit ifcfg-eth0 ==> # vim /etc/sysconfig/network-scripts/ifcfg-eth0 Append the details as follows ==> DEVICE=eth0 ONBOOT=yes ...
