Modes:
mode=0 (Balance-rr) – This mode provides load balancing and fault tolerance.
mode=1 (active-backup) – This mode provides fault tolerance.
mode=2 (balance-xor) – This mode provides load balancing and fault tolerance.
mode=3 (broadcast) – This mode provides fault tolerance.
mode=4 (802.3ad) – This mode provides load balancing and fault tolerance.
mode=5 (balance-tlb) – Prerequisite: Ethtool support in the base drivers for retrieving the speed of each slave.
mode=6 (Balance-alb) – Prerequisite: Ethtool support in the base drivers for retrieving the speed of each slave.
Note: Always append extra configuration in case of a rollback.
1.Configuring Bonding
# cd /etc/sysconfig/network-scripts/
Create a bond file
# vi ifcfg-bond0 DEVICE=bond0 USERCTL=no BOOTPROTO=none ONBOOT=yes IPADDR=10.0.0.10 NETMASK=255.255.0.0 NETWORK=10.0.0.0 TYPE=Unknown IPV6INIT=no
Edit the Ethernet files.
# vi ifcfg-eth0 DEVICE=eth0 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes USERCTL=no # vi ifcfg-eth1 DEVICE=eth1 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes USERCTL=no # vi ifcfg-eth2 DEVICE=eth2 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes USERCTL=no
Due to the fact that /etc/modprobe.conf has been deprecated in RedHat / CentOS 6, the process of bonding network interfaces has changed a bit.
Now instead of defining your bond in your /etc/modprobe.conf, you define it in /etc/modprobe.d/bonding.conf
# vi /etc/modprobe.d/bonding.confWe’ll be using mode=6 (Balance-alb)
Append the following onto the end out your modprobe config file.
alias bond0 bonding options bond0 mode=6 miimon=100
Restart the network service
# service network restart
Enjoy :)
