[0189] Dut 2 The VLAN of the second stream = VLAN starting port 101 + the second Dut-1 = 102

[0190] Dut 2 The source Udp of the first stream = Udp source starting port 1024 + the first stream - 1 + the total number of Dut ports 3 * (2-1) = 1027

[0191] Dut 2 Destination Udp of the first stream = Udp destination starting port 2024 + 1st stream - 1 + Dut total number of ports 3 * (2-1) = 2027

[0193] Dut 2 Udp destination port of the second stream = Udp destination starting port 2024 + second stream - 1 + total number of Dut ports 3 * (2-1) = 2028

[0194] In this embodiment, the functions of copying, increasing, decreasing, etc. between ports and flows are provided; the functions of copying, increasing, decreasing, etc. are also applied to all DUTs.

You can use the increment function to configure the Udp_Src_Port of DUT 1Port 2 as 1025 and the Udp_Src_Port of DUT 1Port 3 as 1026.

[0196] When the customer modifies the configuration of DUT1, it can be copied to other DUTs with one click. The copying rules are as follows:
