[dpdk-users] pktgen can't send packet forever

[Xu, Chenjie]

Hi Mishal,
I have done that. My steps are below:
         ./app/x86_64-native-linuxapp-gcc/pktgen -l 10,11,12 --vdev=virtio_user0,path=/ovs/2a22f95cc275-net1 --no-pci --socket-mem=1024 --master-lcore 10 -- -m 11:12.0 -P
       set 0 dst mac $MAC
       set 0 size 128
       start 0

After “start 0”, pktgen will send packets several seconds and then it just stops to send packet.

Best Regards,
Xu, Chenjie

Hi,

I'm not very sure if I've understood your issue right, but for pktgen to send packets we need to do "start <portlist>" to start sending the packets and "stop <portlist>" to stop sending packets, have you done that?

Dear all,
I'm using pktgen 17.11.3 and pktgen can only send packets a few seconds though pktgen is configured to send packet forever as below:
Tx Count/% Rate   :       Forever /100%

Does anyone know how to fix this issue? By the way, I'm following the below guide to use pktgen:
