The DUT must learn 2X MAC addresses. Measure the time taken to learn The DUT must learn 2X MAC addresses. Measure the time taken to learn
2X MAC in DUT.The test is repeated for "N" times and the values are 2X MAC in DUT. The test is repeated for "N" times and the values are
collected. The convergence time is calculated by averaging the collected. The convergence time is calculated by averaging the
values obtained by "N" samples. "N" is an arbitrary number to get a values obtained by "N" samples. "N" is an arbitrary number to get a
sufficient sample.The time measured for each sample is denoted by sufficient sample.The time measured for each sample is denoted by
T1,T2...Tn.The measurement is carried out using external server which T1,T2...Tn. The measurement is carried out using external server
