Can Juniper generate traffic out of an interface?

Hello, I'm trying to get away from the use of traffic generators like Ixia or Spirent for the sake of removing dependecies.

Scenario:

SUT Port A ----> Port A MX480 Port B MX480 ----> Port B SUT

Note SUT is the same system in the same forwarding domain (vlan 1600)

Question: is there a way to generate L2 frames with vlan tags out of the Juniper interfaces into the SUT?
