RFC Back to Back with pause frames

Problem: 
Why does the RFC 2544 Back to Back test fail to run when the other tests complete?
Solution: 
Back to Back testing requires bursting traffic at the line rate as opposed to shaping the traffic tranmission. If flow control is enabled, in the network, the testset will receive pause frames which can cause the test to abort. Some test equipment may have advanced settings to ignore pause frames but some may be unable to conduct the test unless the flow control is disabled on the network.
