5.2.1. Port Map
 Port Select …: By clicking this button, a Select Ports for Testing window will pop up, allowing you
to select the module cards and the ports you would like to use for the task.
 IP Setup …: For layer2 tasks, the IP Setup button presents gray, which serves no function under

 Source/Destination Port: These two fields display the source/ destination port for the task. Ports
are displayed in IDs in the format of (X, Y, Z) while X is the number of the chassis (which is displayed
on NuStreams-2000i/600i), Y is the slot number where this model card is installed, and Z is the
available port number located on the model card.

Port Map: This field shows how test streams will be transmitted from port to port.
 : To assign how test streams flow from source port to the destination port, click a port from Source
Port, click a port from Destination Port, and then click  button to add them to the Port Map.
 : To remove a port map setting from Port Map, click the setting you would like to remove, and then
click  button to remove it from Port Map.
 Pair >: APMPT-4 will match ports located on the same module card in a back-and-forth manner, and
add them to the Port Map.

Rotate >: APMPT-4 will match ports so the last port will connect to the first port, thus forming a loop.
If you have the same amount of ports on your chassis and DUT, Rotate
allows you to test all DUT‟s
ports simultaneously.
 Reset <: Reset all port map settings in the Port Map.
