Hi All,

When we using http://pktgen.readthedocs.org/en/latest/index.html pktgen-dpdk as a packet generator,

Does the DUT must be run with dpdk ?

Maybe it must runs using sample code, testpmd、l2fwd、l3fwd, etc..?

Thanks a lot !

Best regards,

Leo

Hi Carlos A,

Thanks for reply.

Actually, my points is the DUT side.

The DUT side MUST be running dpdk sample code (ex: testpmd) when using pktgen-dpdk as a packet generator to generate packets, is that right ?

Since we deploy the environment like below:

Pktgen-dpdk <--- network cable ---> DUT

If the DUT had ran without dpdk sample, the pktgen-dpdk does NOT receive the packets.

In other words, the pktgen-dpdk can receive the packets when the DUT has been run with dpdk sample.

Thanks a lot.

Best regards,

Leo

Hello Leo_Yeh,

Thanks for your reply.

The DUT is independent that the DPDK is running, as long as the DUT has the routes setup to send the traffic back to the pktgen-dpdk.

In case that you have more questions related to this, we suggest you to address them to the emails listed at the http://dpdk.org/ml DPDK ML, where they will be further answered.
