Looping back test traffic is possible as follows:
Layer 1: All incoming traffic is looped back unchanged.
Layer 2: All incoming unicast traffic is looped back with the MAC source and destination addresses swapped.
Layer 3: All incoming unicast traffic is looped back with MAC and IP source and destination addresses swapped.
Mode: Manual or Asymmetric
Manual: User must input the destination MAC/IP address of the far-end device along with the type of command.
IP Destination: Enter the IP address of the far-end test set that is to be looped up/down.
Prior to starting the test, manually send the loop up command by pressing the Loop Up button
A "Loop-up successful" message will appear
