+In this mode, NFVbench will send packets from each port to the other port
+(the destination MAC address is set to the other port MAC address).
This can be useful for example to verify that the connectivity to the switch is working properly.
+Such a test can be quickly run using the CLI ``--l2-loopback`` :ref:`option <adv-l2l-cli>`.
+
+For a typical test, packets will be VLAN tagged with the same ID on both ports.
+However, multiple L2 vlan tagged service chains are also allowed,
+which permits testing various configurations and the behavior of the bench itself.
