Soft Loop on interface

[Mosiur Rahman]

Hi All,

I am a beginner in networking.

Is there a way to perform a soft loop on ethernet interface on router for testing RFC2544 with a tester?

Not sure what is the objective here. - i did Long Long ago as i remember, not sure the outcome.

To create a loopback plug, cross pin 1 (TX+) and pin 3 (RX+) together, and cross pin 2 (TX-) and pin 6 (RX-) together
