Hello,

I was wondering whether there are tutorials and general steps to connect a bmv2 switch with SDN controllers, for example, I would like to do something similar to what OVS does when there is no match in a table and sends the packets to the controller for evaluation, how can I do that with bmv2 switches and with other switches that leverage P4, in general?

Currently, I am working with POX and ONOS controllers, and I aim to connect them with my bmv2 switch.

I’d appreciate any help/guidance.

best regards,  
Anthony

Hi @absuarez ,

Here some tutorials to control P4 switches via ONOS:

- [onos/apps/p4-tutorial/README.md at master · opennetworkinglab/onos · GitHub](https://github.com/opennetworkinglab/onos/blob/master/apps/p4-tutorial/README.md)
- [GitHub - opennetworkinglab/ngsdn-tutorial: Hands-on tutorial to learn the building blocks of the Next-Gen SDN architecture](https://github.com/opennetworkinglab/ngsdn-tutorial)
