Link aggregation

The previously mentioned solutions mitigate the risk related to having a FortiGate unit as a single point of failure. However, we need to implement a configuration to prevent a single port (on the appliance or on the network switch) from becoming critical, in case of a failure. We will use link aggregation (typically referred to as NIC teaming, teaming, EtherChannel or Link Aggregation Group) to combine multiple network connections and provide redundancy in case one of the links fails. We can use 802.3ad link aggregation to combine two or more interfaces into a single logical aggregated link. We will also see how to use an automation protocol for operations related to link aggregation, the Link Aggregation Control Protocol (LACP). LACP manages tasks related to the distribution of traffic among the physical interfaces we have aggregated. Without LACP, we should manually set additional parameters for link aggregation. 802.3ad aggregation is managed by navigating to the System...
