The loopback can be applied separately for each one of the interfaces (Eth1 to Eth4) and
can be set with or without MAC Address swapping.
Set the loopback mode for the desired Ethernet port and set the loopback-timeout in

External Line Loopback
The Ethernet traffic from the customer’s end-equipment or Ethernet analyzer is looped

interface between end-equipment and the local system.
When testing a link from one side (local), apply an external line loopback should be
applied on the local unit.
