iPerf3 on Fortigates

(2021-06-16)

Limited iPerf3 on Fortigates

# diag traffictest client-intf port1        <----- Define FortiGate port.
# diag traffictest server-intf port1        <----- Define FortiGate port.
# diag traffictest port 5209                <----- Define iPerf3 port running on the iPerf3 server.
# diag traffictest run -c 45.154.168.155    <----- Upload test to server 45.154.168.155
# diag traffictest run -R -c 45.154.168.155 <----- Download test from server 45.154.168.155
# diag traffictest run -c 45.154.168.155 -P 4 <--- Upload to server with 4 parallel data streams

The server doesn't really work, so it is best if you do this as a client on the fortigate.
