Netflow 9 and Cisco 3850

I am trying to configure netflow 9 on a cisco 3850, the issue that I keep running into is when I apply the monitor on the layer two VLAN interface, I get an error message that reads "Flexable Nfetflow not supported on layer 2 interfaces".

The monitor also does not work on switchport interfaces. Currently I have it configured and working on another 3850, applied to a "routed" interface.

Is there a work around to have it setup on a layer 2 switch?

Also note, the switch only supports Netflow 9 and IPFIX

Any assistance is appreciated.
