Hi Zhao, Kindly check below the dpdk and Mellanox Cx6 DX configurations
[dpdk-22.11]$ cat VERSION 22.11.0 [dpdk-22.11]$ ethtool -i enp4s0f0np0 driver: mlx5_core version: 5.8-1.1.2 firmware-version: 22.35.2000 (MT_0000000436) I have tried with liberal mode, but nothing happened. One more thing is that we are not able to query conntrack stats via testpmd: testpmd> flow query 0 1 conntrack Cannot query action type 52 (CONNTRACK) Regards, Haider ________________________________ From: Bing Zhao <[email protected]> Sent: Wednesday, February 22, 2023 4:18 PM To: Haider Ali <[email protected]>; users <[email protected]> Cc: Ori Kam <[email protected]>; Slava Ovsiienko <[email protected]>; Asaf Penso <[email protected]> Subject: RE: conntrack not working in mlx5 Hi Ali, Which DPDK version are you using? Could you try to use liberal mode firstly? Then the Seq/ACK/Win check will be ignored and only the state change will be tracked.
