Test connection speed between NetApp ONTAP 9.3+ and Windows Client

Today I wanna show you, how to perform a speed test between a Windows Client and your NetApp filer.

Logon to your NetApp filer using SSH.

Set priv to advanced:
netapp::> set -privilege advanced

Warning: These advanced commands are potentially dangerous; use them only when
         directed to do so by NetApp personnel.
Do you want to continue? {y|n}: y
netapp::> y


Start iperf server:
netapp::*> network test-link  start-server


Install and run iperf on Windows:
- Logon into the Windows client
- Download iperf3 and extract it
  https://iperf.fr/en/iperf-download.php#windows
- browse to iperf3.exe and run
  iperf -c serveripaddress


Example execution and output:
iperf3.exe -c 10.1.1.10

Stop iperf server on NetApp:
netapp::*> network test-link  stop-server
