Now this package “org.stratumproject.fabric.montara\_sde\_9\_7\_0” is compiled with maven, because I use a higher version of onos, only support bazel tool compilation, now I use bazel tool to build my own definition of APP, similar to this application “org.stratumproject.fabric.montara\_sde\_9\_7\_0”, However, the delivery was unsuccessful, and the error is the problem in the picture above.

Hi,

Cold you specify the command that you run for strating Stratum on the switch? I suppose that you have started the stratum, barefoot applications on ONOS.  
The driver in the json , used for de discovery od the device should be `"driver": "stratum-tofino"`.

Hi,

1.The command that run for strating Stratum on the switch is

cd bf-sde-9.3.1  
source set\_sde.bash  
. ./set\_sde.bash  
./install/bin/bf\_kdrv\_mod\_load $SDE\_INSTALL /  
$SDE\_INSTALL/bin/dma\_setup.sh  
start-stratum.sh --enable\_onlp=false

2.In the onos cli,I only find the device driver “stratum”，no such driver “stratum-tofino” ,so the driver in the json write is “stratum”. when I write the json, I’m also confused about this driver"stratum-tofino" .

Hi,

1. you are using SDE 9.3.1 while your pipeline seems compiled for the SDE 9.0.0.
2. I don’t know the content of the script `start.stratum.sh` but in my case i run stratum version 22.03:  
`sudo stratum_bfrt -bf_sde_install /home/tofino/SDE-9.7.0/bf-sde-9.7.0/install -bf_switchd_cfg /usr/share/stratum/tofino_skip_p4.conf -bf_switchd_background=false -enable_onlp=false -chassis_config_file ./chassis_config.pb.txt -experimental_enable_p4runtime_translation -incompatible_enable_bfrt_legacy_bytestring_responses`  
Morover, by default the grpc control port exposed by stratum should be 9559. Did you check the version compatibility among stratum version and the sde that you are running? [Releases · stratum/stratum · GitHub](https://github.com/stratum/stratum/releases)

Hi,  
When I use SDE 9.3.1, it is also the same error. Should it not be a problem in this regard, but may it be a problem in other aspects?

Hi,

Could be tha you may have errors at several levels:

- software versioning stratum with SDE

- Maybe you didn’t developed properly you ONOS application, you may try to install fabric-tna([GitHub - stratum/fabric-tna: The SD-Fabric data plane](https://github.com/stratum/fabric-tna)) or this app that i developed tha simply allow to use Reactive Forwarding ([GitHub - Dscano/Basic-tna: This application allows ONOS to control the basic P4 pipeline, deployed for Tofino switch, via the ONOS application reactive forwarding and/or installation of custom flow rules via ONOS REST API .](https://github.com/Dscano/Basic-tna)) on a tofino switch with stratum.

In theory if you are not able to enstablish a connection to the grpc server on your swetch you should see any connection and errors appears periodically in the ONOS/stratum logs. While if you have some issue with pushing the pipeline you should see errors in the logs from onos/stratum.

Hi,

Can I use the code package you sent to compile it into an .oar file using “Maven” or “bazle” to connect to the switch?

Hi,

yes, you can. Those programs are developed according to the ONOS “develop workflow”.

The image below is all ONOS drivers after my startup package “GitHub-Dscano/Basic-tna”, and I wonder why there is no “stratum-tofino” driver in the driver.

@lq1 please try to send compact messages, the stratum driver is ok.  
Why did you activate so many apps?, more in detail you activate also all the apps related to control optical devices and also the `pipelines.fabric`.  
Please apply a step by step approach for your troubleshooting.

hi,  
The previous reply just showed you all the driver information of ONOS, the following picture is the driver information I started myself, I want to know the “driver” in the “tofino-netcfg.json” configuration file you wrote: “stratum-tofino”, I can’t find it in the ONOS driver.

Hi @lq1,

I checked and `stratum-tofino` is correct, is just a matter of driver naming. The `stratum-driver` is enabled by the activation of barefoot driver app . As you can see is an “extension” of barefoot driver.
