Technical Tip: SD-WAN: Performance SLA protocols

[JCPL]

Description	This article explains the different monitoring protocols that can be configured in performance SLAs when using active monitoring.
Scope	FortiGate.
Solution	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.
