Follow up re: capabilities of Basic NIC devices

[Fraida Fund]

Hi, I wanted to follow up on L2Bridge without MAC learning?

It seems based on the discussion at OpenVSwitch link under Complex Recipes doesn’t go anywhere that perhaps this situation has changed.

Could you please share some information on what has changed?

Hi Fraida,

Yes, FABRIC now supports Slices using OVS Bridges using NIC_Basic. An example notebook can be found here: https://github.com/fabric-testbed/jupyter-examples/blob/main/fabric_examples/complex_recipes/openvswitch/openvswitch.ipynb

We do have following constraint though for this to work.

Host Considerations:

Because of constraints imposed by NVIDIA/Mellanox, when utilizing NIC_Basic for an OVS bridge experiment, it is advisable to deploy the VM responsible for running the bridge on a separate host from the VMs linked to the bridge.

Additionally, it’s worth noting that this condition does not apply to NIC_ConnectX_5 and NIC_ConnectX_6 configurations.

Thanks,

Komal
