An interface speedtest can be performed on WAN interfaces in the GUI. The results of the test can be added to the interface's Estimated bandwidth. The estimated upstream and downstream bandwidths can be used in SD-WAN service rules to determine the best link to use when either Maximize Bandwidth or Best Quality strategies are selected.
An SD‑WAN Network Monitor license is required to use the speedtest. The License widget and the System > FortiGuard page show license status.
- Go to Network > Interfaces.
- Edit a WAN interface. The interfaces can be grouped by role using the grouping dropdown on the right side of the toolbar.
- Click Execute speed test in the right pane.
- When the test completes, click Apply results to estimated bandwidth.
The speedtest results are used to populate the Estimated bandwidth fields.
- Click OK.
The FortiGate must be connected to FortiGuard, and able to reach either the AWS or Google speedtest servers.
