      Description

      Using voltha 2.0 core with containerized adapters, after provisioning, enabling and installing traffic flows (cTag=33, sTag=44), the flows are visible correctly in the voltha logical_device.

      But in the OLT and ONU devices, the flows have the same direction:

      • on the OLT device, both flows are from the PON port to the NNI port
      • on the ONU device, both flows are from the UNI port to the PON port

      This was also the case in the demo made on 9/5/2019 : https://www.youtube.com/watch?v=GzlA8DbjteQ

      Flows on logical_device:

      Please find attached the voltha CLI commands showing the ports and flows on each device (logical_device, olt, onu), and the logs from the ofagent, core and adapters.
