Hi,
I have a problem with using ovs-dpdk on Bluefield-2. after using this Nvidia document(Mellanox Interconnect Community), these errors occured:

ovs-vsctl show

error: “Error attaching device ‘0000:03:00.0,representor=[0,65535]’ to DPDK”
Port ovs_dpdk_br0
Interface ovs_dpdk_br0
type: internal
ovs_version: “2.15.1”

systemctl status openvswitch-switch.service

ovs|00057|dpdk|ERR|Invalid port_id=1024

Any idea how should I solve these errors?

Hi @rtaheri,

Please check if “dpdk_initialized : true” under:
“ovs-vsctl --no-wait list Open_vSwitch .”
If it’s “false” it means you didn’t compile or point to DPDK tree, check the OVS compile log where it checks for DPDK folder.

Best Regards,
Chen

Thanks for your response

I checked dpdk_initialized and it’s true.

Is there any reason that makes this error?
