RFC2544 test running 3 ports into 1 port (spoke/hub) . There is frame loss always(33 percent at 60 percent load)

ports are all 100meg type . This is not an over subscribe ? Should he be only testing 1 to 1 at any given time . Using the partial mesh option .

Why would he be seeing frame loss consistently when running the test ? Should i be pausing in between frames longer than 15 seconds to allow buffers to clear on switch ?

Need some more information with respect to the configuration and setup. Is the aggregate load from the 3 ports into 1 ports 60% load (assuming yes)? Is traffic bi-directional? Is the spoke/hub full duplex or half duplex?

Ports were over subscribed . Best way to get this done turned out to be fully meshed test and not using RFC2544 .

Thank you
