Hi Chengappa:
How many ports do you use?
In the information you provided, I think you used only one port.
Many of the case in dts need two ports or more.
e.g. test suite pmd_bonded need 4 ports, you provide 1, it failed at set_up_all show "blocked set_up_all failed" issue.

Hi chengappa,
         Here are my points:
1, the link might have some issues, such as link down
         From the result "receive 0 , expect 64", I think , the link is down
         You can check your link first before running dts.
2, DPDK will change during different version , so DTS will change with it.
         Which DPDK and DTS 's version do you use?
         From the failed result "set up failed" and timeout , I think your testpmd started failed.
         Logs in output, you can check them to find the real reason, maybe testpmd's parameters changed.

Subject: [dts] low pass rate executing dts complete test suite

Hello DTS community,

As we were investigation on DTS for Niantic (Intel Corporation 82599ES 10-Gigabit) platform and we are seeing very less pass rate.

We were under the assumption if we take care of the initial pre-requisites for TESTER and TARGET DUT as described here - https://dpdk.org/doc/dts/gsg/sys_reqs.html the DTS framework help us achieve a good pass rate.

Could you please help me by letting know if there are any fine tuning for the TARGET DUT so that I can see a better numbers than the current pass rate of 12.4%

[root@tester dts]# cat output/statistics.txt
Passed     = 17
Failed     = 45
Blocked    = 68
Pass rate  = 12.4



Some of the specification on the TARGET DUT and current running configuration are as follows
