SD-WAN bandwidth monitoring service

The bandwidth measuring tool is used to detect true upload and download speeds. Bandwidth tests can be run on demand or automated using a script, and can be useful when configuring SD-WAN SLA and rules to balance SD-WAN traffic.

The speed test tool requires a valid SD-WAN Bandwidth Monitoring Service license.

The speed test tool is compatible with iperf3.6 with SSL support. It can test the upload bandwidth to the FortiGate Cloud speed test service. It can initiate the server connection and send download requests to the server. The tool can be run up to 10 times a day .

FortiGate downloads the speed test server list. The list expires after 24 hours. One of the speed test servers is selected, based on user input. The speed test runs, testing upload and download speeds. The test results are shown in the command terminal.

To download the speed test server list:

# execute speed-test-server download
Download completed.

To check the speed test server list:

# execute speed-test-server list
