我可以只运行一个端口在 Pktgen 中连续发送数据包吗？

Question

I want to accomplish to send packet continuously in port "0",and I have done some configuraition:

./app/x86_64-native-linuxapp-gcc/pktgen -l 0-2 -n 4 --proc-type auto --socket-mem 1024 -b 00:08.0 -- -P -m "[1].0" 

and in the interactive CLI I set something:

Pktgen>set 0 src ip "192.168.12.2/24"
Pktgen>set 0 dst ip "192.168.12.3"
Pktgen>set 0 proto udp
Pktgen>set 0 count 0
Pktgen>set 0 rate 50
Pktgen>set 0 size 64
Pktgen>start 0

But according to the page main display, the port 0 just transmit few packets and stop to send packet anymore,even I stop 0 and start 0 again, there is no any response.

Pktgen must config two dpdk ports? when I config two dpdk ports and run scripts/rfc2544_tput_test.lua , it works well,I want to know why...

Yes, you can. It work seamlessly. Only requirement, the other side should be able to detect link state change.
