Hello Klemen,
I made a test in the lab and found out that this feature is not present on the switch even though it is described in its Administration Guide.
I am really sorry for the inconvenience this might cause you.
What I can suggest is that you call our support line, so we can open up a case for that and escalate it.
You can find the corresponding phone number to reach us here:

Kind regards,
