Hi @guxiaofei,
-
are you loaded the fabric-tna pipeline in onos?
-
because at first singth “pipeconf”: “org.onosproject.fabric.tofino” seems a strange app to me. I mean, I’m not aware of a pipeline called like that. This should be the correct pipeline name org.stratumproject.fabric.montara_sde_9_7_0 and is referred to this project GitHub - stratum/fabric-tna: The SD-Fabric data plane
