How to run stratum on tofino software model ?

[Xiaochou Chen]

on ubuntun 16, I can successfully run the following command
./run_tofino_model.sh -p simple_l3
./run_switchd.sh -p simple_l3

It looks like I can run the P4 program on the tofino software model, but how can I run stratum on the tofino software model?

Can anyone tell me the steps to do this? Or where can I get the information I need?

Hi Xiaochou,

https://github.com/stratum/stratum/blob/main/stratum/hal/bin/barefoot/README.run.md#running-stratum-on-tofino-model

Does this help?

Best,

Max

Hi Xiaochou,

Tofino-model does not need a portmap. Something must have gone wrong in the startup process.

Consider trying with newer versions: https://hub.docker.com/r/stratumproject/stratum-bfrt/tags?page=1&ordering=last_updated

Also check out how tofino-model is used in fabric-tna:

Followed those steps and I made docker image:   stratumproject/tofino-model:9.3.1

Then, run command:

Afterwards, I ran it in another terminal window, but encountered a problem:

Can you give me an example of a port-map.json that can be used for tofino-model?
