connection error

[P4-WCZ]

The scenario I want to achieve is: execute p4runtime-shell in the ubuntu virtual machine to achieve normal communication with the P4 commercial switch (the switch has been installed with the runtime-server service normally, port 50051). You mentioned at the end that it can support P4 commercial Switch. But I cannot establish a connection normally. The above is the error of the package when executing the script Can you help me take a look。

I cannot provide technical help with the Tofino switch as I no longer work at Barefoot / Intel, and I no longer have access to the software. I recommend reaching out to customer support if you are having issues using P4Runtime with Tofino. You may want to try and troubleshoot yourself as well, by looking at available logs on the switch.

I had similar problems. Here is what worked for me (SDE 9.4.0 with P4RT support):

1. Compile your p4 program on the switch using the provided compiler. Generate the p4info.
2. Modify the run_switchd.sh - Add the --p4rt-server 0.0.0.0:50051 parameter to the actual bf_switchd call
3. Start the switch with ./run_switchd.sh --skip-p4 -p <yourProgram> (Important to start it with your actual binary AND --skip-p4 - Otherwise the switch seg-faults - don't ask me why 🤷‍♂️)
4. Optional: Copy context.json, tofino.bin, <program>.p4info.pb.txt to your runtime-shell host
5. Use the generator script in the repo to create the necessary<yourBin>.bin
6. Call python3 -m p4runtime_sh --grpc-addr <IP>:50051 --device-id 0 --election-id 0,1 --config <program>.p4info.pb.txt,<yourBin>.bin

Hope that helps :)

Hello,     Wow, I was surprised to receive your email. My guess is that my SDE version(8.9.1) is too low and the Runtime function is not adapted. I may need to contact the device manufacturer to update the SDE. Finally, thank you very much for sending me an email and telling me the operation steps in detail, thank you. = =

Thanks， wang

Hello,

I'm facing a similar problem (with SDE 9.7.0). Could you figure out how to resolve the problem @P4-WCZ? I followed your instructions @Mtze, and here is the status and the error I'm getting.

After "Add the --p4rt-server 0.0.0.0:50051 parameter to the actual bf_switchd call Start the switch with ./run_switchd.sh --skip-p4 -p \<yourProgram>" the P4Runtime is listening:

Now, when I try to run p4runtime-shell (python3 -m p4runtime_sh --grpc-addr localhost:50051 --device-id 0 --election-id 0,1 --config p4info.pb.txt,out.bin), I get:

Then the switch seg-faults with the following error:

Can you help me to resolve the issue. Thanks.

I am facing the same issue. @mehdiazf were you able to resolve this?
