Hi Juraj, The current issue is when running DTS with the newest release of Tex v2.89. It will report an error: =========================================================================================================================== pktgen: ssh root@172.18.0.40 pktgen: cd /opt/trex/v2.89;./t-rex-64 -i --cfg /opt/trex/v2.88/trex_cfg_bnxt.yaml Exception happened in [cd /opt/trex/v2.89;./t-rex-64 -i --cfg /opt/trex/v2.88/trex_cfg_bnxt.yaml] and output is [Starting Scapy server......... Scapy server is started The ports are bound/configured. Starting TRex v2.89 please wait ... ERROR in DPDK map Could not find requested interface 5f:00.0 Killing Scapy server...

So I will update the 480 ticket to track this issue.
