Link aggregation is a way of grouping two or more physical interfaces into one logical interface, to get more throughput and also to provide a "failover" option in case one of the physical interface fails. 


In case "eth0" fails we would still have "eth1" serving the host:



For the logical teaming interface, we use two interfaces on a host "eth0" and "eth1" and we "team" them up.

Creating a "team interface":

We create the logical "teaming" interface as below:


Associating Ethernet interfaces with the team interface:

We associate "eth0" and "eth1" with the team interface "team":


And the same for "eth1":


We can check the connection using the below:


Or using the below command, we can check the interfaces:
