Ok, I will check the test_pmd documentation and try to do this test: I'm just starting on DPDK :). > Please also send me the 'lspci | grep Ethernet? output. I included one line in my original email above (plus extract of lspci -vn), here is the full output of the command: 01:00.0 Ethernet controller: Intel Corporation 82598EB 10-Gigabit AF Dual Port Network Connection (rev 01) 01:00.1 Ethernet controller: Intel Corporation 82598EB 10-Gigabit AF Dual Port Network Connection (rev 01) 05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

On the first machine t1 : root at t1:~/pktgen-dpdk# ./app/app/x86_64-native-linuxapp-gcc/pktgen \ -c e -n 1 --proc-type auto -- -m '[2:3].1' -P -f t1-t3.pkt -N And on the other machine t3: root at t3:~/pktgen-dpdk# ./app/app/x86_64-native-linuxapp-gcc/pktgen \ -c e -n 1 --proc-type auto -- -m '[2:3].1' -P -f t3-t1.pkt -N The two "-f" pkt files are attached to this email, I do "start 1" manually at the pktgen prompt.
