4.3 Test Setup

Figure 4-1 shows the block diagram of the test setup. The setup consists of a Jacinto 7 processor EVM, TIDA-020071, DP83TC812EVM-MC, DP83TG721EVM-MC, an Ethernet Switch, a standard PC, and cable assemblies.

TIDA-020071 IP network bandwidth test setupFigure 4-1 IP network bandwidth test setup

iPerf3, an open-source tool used to measure network performance and bandwidth, and is already integrated in TI's SDK. Use iPerf3 with the following commands after an IP address is assigned to the Ethernet port. iPerf3 can be used to test each interface individually or when creating multiple server instances on different ports, multiple client connections can be established to test multiple interfaces simultaneously.

Run the following command on the PC (server):

iperf3 -s

Additionally, run the following command on the Jacinto 7 (client):

iperf3 -c 192.168.1.1 (the IP address of the server)
