Technical Tip: SD-WAN: Performance SLA protocols

FortiGate can choose the best path based on protocol-specific data, enhancing load balancing and failover for key applications.

In the GUI, users can access only three monitoring protocols: Ping, HTTP, and DNS. However, additional monitoring protocols are configurable through the CLI:

CLI:

config system sdwan

    config health-check

        edit <name of Performance SLA>

            set protocol <protocol>

                …

        next

    end

end

Within the available protocols, in addition to those shown in the GUI, it is possible to configure the following:

• tcp-echo: Use TCP echo to test the link with the server.
• udp-echo: Use UDP echo to test the link with the server.
• https: Use HTTPS-GET to test the link with the server, this option is only available after v7.4.1 and above.
• Twamp: Use TWAMP to test the link with the server.
• tcp-connect: Use a full TCP connection to test the link with the server.
• ftp: Use FTP to test the link with the server.
