friends, what a good day, a question: Is it possible to configure a backup port in the fortigate? that is, in the FG I have x ports that are being used and 2 available. I would like to know if it is possible to configure a backup port in case a port of my LAN A goes down and the backup LAN B port takes over.
Link aggregation (IEEE 802.3ad) enables you to bind two or more physical interfaces together to form an aggregated (combined) link. This new link has the bandwidth of all the links combined. If a link in the group fails, traffic is transferred automatically to the remaining interfaces. The only noticeable effect is reduced bandwidth.
In a redundant interface, traffic only goes over one interface at any time. This differs from an aggregated interface where traffic goes over all interfaces for increased bandwidth. This difference means redundant interfaces can have more robust configurations with fewer possible points of failure. This is important in a fully-meshed HA configuration.
