Cisco 3850 Soft Loop For testing

Novice Question:

I have a new circuit turned up. I need to test it before handing off to the customer.

we do this testing remotely all the time with the 3400 switches,
i add "ethernet loopback facility vlan 1234(circuit we are testing) mac-address swap timeout none supported"
to our uplink interface, the vlan i built out to our EXFO test head, set up test head and run the test.

ok so now we have a circuit that is running through a 3850 and said process above does not work.

is this possible on the 3850 without going onsite with a loopback connector
