The core configurations description is: - 2C/1T: 2 Physical Cores, 1 Logical Core per physical core - 4C/1T: 4 Physical Cores, 1 Logical Core per physical core Prerequisites ============= This test does not requires connections between DUT and tester as it is focused in PCAP devices created by Test PMD. It is Test PMD application itself which send and receives traffic from and to PCAP files, no traffic generator is involved. Test Case: test_send_packets_with_one_device ============================================ It is necessary to generate the input pcap file for one interface test. The pcap file can be created using scapy. Create a file with 1000 frames with the following structure:: Ether(src='00:00:00:00:00:', dst='00:00:00:00:00:00')/IP(src='192.168.1.1', dst='192.168.1.2')/("X"*26)) goes from 0 to 255 and repeats. The linuxapp is started with the following parameters: :: -c 0xffffff -n 3 --vdev 'eth_pcap0;rx_pcap=in.pcap;tx_pcap=out.pcap' -- -i --port-topology=chained Start the application and the forwarding, by typing `start` in the command line of the application. After a few seconds `stop` the forwarding and `quit` the application. Check that the frames of in.pcap and out.pcap files are the same using scapy. Test Case: test_send_packets_with_two_devices ============================================= Create 2 pcap files with 1000 and 500 frames as explained in `test_send_packets_with_one_device` test case. The linuxapp is started with the following parameters: :: -c 0xffffff -n 3 --vdev 'eth_pcap0;rx_pcap=in1.pcap;tx_pcap=out1.pcap,"eth_pcap1;rx_pcap=in2.pcap;tx_pcap=out2.pcap' -- -i Start the application and the forwarding, by typing `start` in the command line of the application. After a few seconds `stop` the forwarding and `quit` the application. Check that the frames of the in1.pcap and out2.pcap, and in2.pcap and out1.pcap file are the same using scapy.
