Normally I use 'start <portlist|all>'
pktgen> start 0 # Start port 0 sending
pktgen> start 0,3 # Start port 0 and 3 sending
pktgen> start 0-3 # start port 0, 1, 2 and 3 send packets.
pktgen> start all # start sending on all ports
pktgen> stp # stop sending on all ports
pktgen> str # start sending on all ports
On the main screen is the single packet send configuration for the ports. You need to make sure you set your dst mac to the correct DUT MAC address. If you are fowarding L3 packets then you need to make sure the IP dst/src addresses are correct.
set mac <portlist> etheraddr - Set MAC addresses 00:11:22:33:44:55
You can use 0011:2233:4455 format as well
set ip src|dst <portlist> ipaddr - Set IP addresses
set ip dst 0 192.168.0.10
set ip src 0 192.168.0.1/24
Let me know if that helps.

Just to give you the background .I need to test the packet throughput performance of one of my device using DPDK .
The DUT is connected to my Linux host machine with one of the port and I want to run the Pktgen on my host machine to send the packets to the DUT where DPDK (Testpmd app) is running in fwd rx_only mode.I have setup one of the network port as igb_uio port and using it .
I'm able to compile and run the pktgen with start all but I don't know how to configure the pktgen to send packets to DUT.
I want to know the steps and exact commands required to send packets to my DUT .
