Mellanox 100GE Qsfp pci card

Hello,

We are installing a Mellanox 100GE Qsfp pci card to our server, but it does not see VYOS. The version we are using is 1.5-rolling-202412100007. Since I do not know how to build, I am opening a topic. Is there a ready-made iso build? Our server is HP DL380p Gen8.

What model of cards are they? And what does lspci -v | grep Mellanox and lspci -nnk | fgrep -A5 Network show?

Sometimes you need to use Mellanox tools to set the card to the right mode, like not Infiniband.

Also is the VyOS installed on bare-metal or some VM/Hypervisor in between?

What is the result if you liveboot a Debian 12.x ISO?

ConnectX cards work out of the box in VyOS, no special drivers/image needed.

The VPI versions default to InfinitiBand and need to be switched to Ethernet mode using the MFT tools package (easiest to do with a Debian Live OS).

As mentioned above, check if the card shows up in lspci (should independent of IB mode). If not then it is more likely an issue with PCIe or passthrough.
