L2fwd using Trex #3

Open shashankbr11 opened 3 years ago

shashankbr11 commented 3 years ago

Hi,

I have been testing the L2fwd application of DPDK by sending packets from Trex v2.82 in a loopback manner. The issued faced here is that if L2fwd application is started on the DUT and then starting the Trex traffic generator will give 'Invalid MAC'. This must be due to the L2fwd taking access of the interfaces which Trex is trying to send packets to.

However if I reverse the order and start Trex first and then the L2fwd application at the DUT, then Trex continues to send packets. In this case the L2fwd statistics displayed at regular intervals doesn't show the actual no. of packets sent from Trex, but is showing a very less no.

How did you send traffic from Trex to the L2fwd and manage to get the statistics? Could you please suggest your method of configuration?

With regards, Shashank

Hi @shashankbr11 this looks like a question specific to l2fwd that comes with DPDK and not the GPU version (this one). I'd suggest you send a message to the DPDK users list.
