Network bonding applies to various methods of aggregating multiple network connections in parallel in order to increase throughput and to provide redundancy in case one of the links should fail.
A Link Aggregation Group (LAG) combines a number of physical ports together to make a single high-bandwidth data path, so as to implement the traffic load sharing among the member ports in the group and to enhance the connection reliability.
Redundancy is the key factor in mission critical environments where downtime is not an option.
Using network bonding may require some switch configuration. There are seven modes of network bonding in Linux. For more information visit the following url.
This section explains how to use Adaptive transmit load balancing (balance-tlb) and define the network bridges over those virtual interfaces. The balance-tlb Linux bonding driver mode, does not require any special network-switch support.
Edit your interfaces configuration
sudo vi /etc/network/interfaces
Define slaves to the bonding interface
In this example, the eth0 and eth1 are combined as slaves to the bonding interface bond0, and eth2 and eth3 are combined as slaves to the bonding interface bond1.
auto eth0
allow-hotplug eth0
iface eth0 inet manual
bond-master bond0
auto eth1
allow-hotplug eth1
iface eth1 inet manual
bond-master bond0
auto eth2
allow-hotplug eth2
iface eth2 inet manual
bond-master bond1
auto eth3
allow-hotplug eth3
iface eth3 inet manual
bond-master bond1
auto bond0
allow-hotplug bond0
iface bond0 inet manual
bond-mode balance-tlb
bond-miimon 100
bond-downdelay 200
bond-updelay 200
bond-slaves eth0 eth1
auto bond1
allow-hotplug bond1
iface bond1 inet manual
bond-mode balance-tlb
bond-miimon 100
bond-downdelay 200
bond-updelay 200
bond-slaves eth2 eth3
Define Network Bridges Over Bonding Interface
The network bridges are defined in the same way described in the previous sections. Each bridge only requires to define the interface (in this case bond0 and bond1) as the value of the parameter bridge_ports:
auto xsnow0
iface xsnow0 inet static
bridge_ports bond1
address 192.168.7.1
netmask 255.255.255.0
network 192.168.7.0
broadcast 192.168.7.255
auto xpub0
iface xpub0 inet static
bridge_ports bond0
address 150.241.212.36
gateway 150.241.212.1
netmask 255.255.255.0
broadcast 150.241.212.255
network 150.241.212.0
dns-nameservers 150.241.212.11 150.241.212.26
