Hi all,
I’m new to DOCA SDK. I’m trying to run the example applications but I’m getting the following error, can anyone help?

Hi! Can you share your output of ovs-vsctl show? I am trying to repeat this in my lab and want to make sure I’ve got this setup the same way.

Thanks!

It might be possible that you’re on the DOCA 1.0 release and following the DOCA 1.1 (SDK 0.2) guide for running the sample application. Stateful flow table support was added in DOCA 1.1

See if these instructions work:

/opt/mellanox/doca/examples/url_filter/bin/doca_url_filter -a 0000:03:00.0,class=regex:eth,representor=[65535],sft_en=0 –p

Alternatively, upgrading or reimaging to the DOCA 1.1 release should resolve this one.

Hi jubetz,
I don’t know how to check the version number of DOCA. Could you tell me?
But I think I should install DOCA 1.1.
I installed it through nvidia_sdk.
https://developer.nvidia.com/networking/doca/getting-started
And the version downloaded on the host side looks like v1.1.

$ ls nvidia_sdk/
DOCA_1.1_Linux  DOCA_1.1_Linux_BLUEFIELD2_DPU_TARGETS  DOCA_1.1_Linux_host

Hi,

The SFT error you received is usually shown when supplying the DOCA application an SF (Scalable Function) without first setting them to “trusted”. You can find more information about it in the Scalable Function Documentation.

As for the DOCA version, it looks like you installed DOCA 1.1, meaning you have everything needed for testing the application. The configuration steps should be:

  1. Set the SFs to “trusted”
  2. Create 2 new SFs
  3. Configure OVS to use the newly created SFs so the bridges will match the application’s system diagram
  4. Complete all application prerequisites - (huge pages and mlx-regex)
  5. Execute the application

Good luck!

Hi eitkin, thank you very much. Now it works fine.
