Re: [dpdk-users] Problems running test-pipeline.

["Zhang, Roy Fan" <roy.fan.zhang@intel.com>]

Hello,

Thank you for using DPDK.

testpipeline mainly passes the received packets to different tables inside pipeline, and, if the pipeline works correctly, forwards the packets back to output ports. 

To use testpipeline, you may have to have Ethernet packets sending to the correct port(s) continuously. 
And the only way to check if the pipeline correctly is to monitor the port output seeing if the pipeline has forwarded the packets back. There is no interactive commands for testpipeline.

Please check if your port is physically connected. To avail the purpose of testpipeline, please connect your server running the program with the with device capable of generating and monitoring packet flows, like a packet generator. 
If the answer is yes, please bond different ports to dpdk and run the program again.

Regards,
Fan
