Description This article describes how to create an aggregation interface 802.3ad (LACP) using two or more (if necessary) physical interfaces.
Scope FortiGate v7.X.
Solution

802.3ad is an IEEE specification that allows combining multiple physical ports into one logical port. It is also known as the Link Aggregation Control Protocol (LACP). The benefits can be but no limit to bandwidth increase, protection against anomalies, load balancing, improvement to fault tolerance.

 

To create an aggregate interface, go to Network -> Interfaces:

If the physical interfaces are members of a Hardware/Software/VLAN Switch, remove the desired ones from it:
