How many ethernet ports of DUT are required for RFC2544 testing ?

How many ports of a switch are required for RFC2544 testing ? I started Back to Back testing with 2 ports. As I am new to testing so I have doubt. Do I need to use all the ports of a switch for better results ? Can an experience tester guide me in this regard ?

RFC 2544 was actually written before switches were developed; at least its predecessor RFC 1944 was. At that time it was only considering a smaller number of ports. So really even a single port-pair is appropriate. However, it is generally better that you place the load across all ports of a device to test it under the maximum load. In the end, it's up to what your goal is for the test as the RFC is not that specific about it.

Agreed with Larry, RFC 2544 defines the ideal testbed to have a tester with both transmitting and receiving ports. Hence a single port pair should be acceptable.
