IP Connectivity Issues on Intel Tofino 2

[PantelisMalekas]

Hi all,

I have an Intel Tofino 2 switch and I want to set up a Stratum process/container on a SONiC OS, so I may test out some P4 pipelines in a realistic environment. However, I have a bit of difficulty setting an IP on the Tofino switch. Here's the complete rundown:

The first time I set up the switch I got the BMC console correctly. After running `wedge_power.sh reset; sol.sh` I got to the ONIE OS. After stopping the auto-discovery process, I connected an ethernet cable from a Mikrotik Switch and I received an IP. After installing SONiC from an HTTP server on the same network, I logged in and it had also received an IP from Mikrotik (a different one from ONIE, but both of them worked).

Now, suddenly the IP from SONiC suddenly stopped being operational, and so I couldn't connect remotely using SSH etc. After going to the DC and entering Tofino using a console port (like the first time), I saw that SONiC still had the assigned IP, even though it wasn't responding to/from anything. I decided to exit, go back to BMC and run `wedge_power.sh reset; sol.sh` again. I got the following result: The SONiC OS lost its IP permanently. It couldn't get one using Mikrotik or manually anymore. Same thing also occurred when I logged into the ONIE OS. The BMC console OS however managed to get a proper IP from Mikrotik.

Now, I decided to re-install SONiC with a different version (the previous version was incompatible with the desired Stratum setup anyway) and I did so using a USB stick. However the new SONiC OS can't receive an IP either.

Do we have any idea what could be the issue? I have thought of resetting Tofino 2 so I could begin the process all over but I wasn't able to find anything regarding this action. Right now I can connect to the BMC-received IP remotely and then run `sol.sh` to enter SONiC. But, I have zero internet connectivity, so I am not very certain that the Stratum set up can continue.

I understand that this a long post, but I wanted to be as detailed as possible. Any assistance would be greatly appreciated.

Best regards,
Pantelis
