[dpdk-users] Newbie: Help requested to get l2fwd example working

[David Aldrich]

Hi

I’ve tried sending packets with packETH, and I have tried using testpmd (instead of l2fwd) to receive them.  I still see no packets.

Any other suggestions please?

Best regards

David

Hi David,

You can try to replace it with “Linux pktgen”(no need of DPDK-driver for NIC) or “DPDK pktgen”(Need DPDK-driver) in your packet sending host. They both work fine for me.

Hi Zhilong

I have written a simple program in C, which sends udp packets.

Which sender are you using?

Hi David,

A similar problem happened to me before. However when I changed another packet sender, it works fine. What’s your packet sender that you sending UDP packets?

Best regards

Hi Zhilong



In the EAL log of your command “./build/l2fwd -c f -n2 -- -q 2 -p 3”, it showed “
Port 0 Link Down”. So are there some problems in your port connection? Or you
can send packets to Port 1to check statistics.

I am only sending packets to port 1, and these packets are not indicated in the statistics. I need to find out why.

BR

David
