+Assuming you have not changed the default ports in the chart,
+you can use this command to access the ONOS CLI:
+
+```shell
+ssh karaf@<pod-ip> -p 30115

+
+The default ONOS password is `karaf`.

+AttWorkflowServiceInstances are created once the ONUs reach are in `oper_status=ACTIVE`,

+```
+
+If no ports are shown an error has occurred in VOLTHA, if everything
+looks correct you can proceed to the next step.
+
+## Check the status in ONOS
+
+Connect to the [ONOS CLI](../../../charts/onos.md#accessing-the-onos-cli)
+and check devices:
+
+```shell
+
+onos> devices
+id=of:0000000000000002, available=true, local-status=connected 5h33m ago, role=MASTER, type=SWITCH, mfr=Accton Corp., hw=x86-64-accton-as6712-32x-r0, sw=ofdpa 3.0.5.5+accton1.7-1, serial=671232X1538038, chassis=2, driver=ofdpa3, channelId=10.90.0.120:46211, locType=none, managementAddress=10.90.0.120, name=AGG_SWITCH, protocol=OF_13
+id=of:000000000a5a007a, available=true, local-status=connected 4h19m ago, role=MASTER, type=SWITCH, mfr=VOLTHA Project, hw=, sw=, serial=10.90.0.122:9191, chassis=a5a007a, driver=voltha, channelId=10.233.102.179:59154, locType=none, managementAddress=10.233.102.179, name=SHAD OLT, protocol=OF_13
+```
+
+You should see the aggregation switch and the logical device representing the PON.
+If you can't see the logical device (`mfr=VOLTHA Project`) then an error occurred
+in the communication between the VOLTHA ofagent component and ONOS.
+
+Check if ONOS can see the active ports on the logical device:
+```shell
+onos> ports -e of:000000000a5a007a
+id=of:000000000a5a007a, available=true, local-status=connected 4h21m ago, role=MASTER, type=SWITCH, mfr=VOLTHA Project, hw=, sw=, serial=10.90.0.122:9191, chassis=a5a007a, driver=voltha, channelId=10.233.102.179:59154, locType=none, managementAddress=10.233.102.179, name=SHAD OLT, protocol=OF_13
+  port=16, state=enabled, type=fiber, speed=0 , adminState=enabled, portMac=08:00:00:00:00:10, portName=ALPHe3d1cfe3
+  port=32, state=enabled, type=fiber, speed=0 , adminState=enabled, portMac=08:00:00:00:00:20, portName=ALPHe3d1cf9d
+  port=65536, state=enabled, type=fiber, speed=0 , adminState=enabled, portMac=00:00:00:01:00:00, portName=nni-65536
+```
+
+If you don't see the ports there's again some issue in the communication between
+the VOLTHA ofagent component and ONOS.
+
+If everything looks correct you can move to the next step.
+
+## Check events in Kafka
+
+### Use Kibana
+
+If you have installed the [Logging component](../../../charts/logging-monitoring.md#logging-dashboard) of the platform you can then look in
+Kibana for these events.
+
+Connect to the dashboard an search for events in the `onu.events` topic:
+
+![Kibana ONU events](./screenshots/kibana_onu_events.png "Kibana ONU events")
+
+### Check in Kafka
+
+You can install kafkacat on the POD using this command:
+
+```shell
+helm install -n kfc cord/kafkacat
+```
+
+Then you'll need to access the container and list the messages on the `onu.events`
+topic:
+
+```shell
+kubectl exec -it kafkacat-7f45f65485-2lgp8 bash
+root@kafkacat-7f45f65485-2lgp8:/# kafkacat -b cord-platform-kafka -t onu.events
+```
+
+If evetyhing is correct you should see:
+
+```shell
+{"timestamp":"2018-12-19T22:34:00.755Z","status":"activated","serial_number":"ALPHe3d1cfe3","uni_port_id":16,"of_dpid":"of:000000000a5a007a"}
+```
+
+If you can see events in Kafka you can proceed with the next step.
+
+## Check the AttWorkflowDriver container
+
+This is the last step of the process, if you have events in kafka, you should
+check the logs of the `att-workflow-driver` container.
+
+You can do that using this command:
+```
+kubectl logs -f att-workflow-att-workflow-driver-7c8bc95894-xgxts
+```
