• start ONOS

• activate the SNMP southbound app :

  Code Block
  onos> app activate org.onosproject.snmp

• activate the SNMP drivers for your device (i.e. lumentum drivers) :

  Code Block
  onos> app activate org.onosproject.drivers.lumentum

  Pay attention: if your drivers already depend upon the snmp app only the second step is needed.

• give ONOS the information regarding the device and which driver to use for your device in a json file. You need to specify username, password, ip and port. If you wrote a specific driver that has also to be changed form the standard "rest" one.

  Code Block
  { "devices": { "snmpnetconf:<ip>:<port>": { "basicsnmp": { "driverip":<your_driver_name> } <ip>, } }, "appsport":{ <port>, "org.onosproject.snmp":{ "devicesusername":[{ <username>, "usernamepassword":<username>, <password> "password":<password>}, "ipbasic":<ip>, { "portdriver":<port> <driver-name> }] } } }

  You can also add other information, more than the driver, to the basic device configuration information: "type": "<device-type>", "manufacturer": "<device-manufacturer>","hwVersion": "<hw-version>","swVersion": "<sw-version>".

   

• upload the configuration you just wrote to the instance of ONOS you are running, in our case localhost:

  Code Block
  <your_machine>~$ curl -X POST -H "content-type:application/json" http://localhost:8181/onos/v1/network/configuration -d @<path_to_your_json_configuration_file> --user onos:rocks

  or 

  Code Block
  <your_machine>~$ onos-netcfg localhost <path_to_your_json_configuration_file>

• Check if the device is present in ONOS:

  Code Block
  onos> devices

  should return, among other devices also something like:

  Code Block
  onos> id=snmp:127.0.0.1:1, available=true, role=MASTER, type=SWITCH, mfr=unknown, hw=unknown, sw=unknown, serial=unknown, ipaddress=127.0.0.1, driver=lumentum, name=rest:127.0.0.1:1

  If the device is not present the could have been one or multiple errors and you have to check the logs.

  • for localhost logs

    Code Block
    <your_machine>~$ tl

    or for remote logs

    Code Block
    <your_machine>~$ ol

  • verify that the logs don't contain SNMP related exceptions. In case error are present in the logs it could mean that the device was not able to reply on the given IP and Port. Verify Ip and Port in the Json file you posted and retry. If any other exception is present, such as no device name, please read the log and react to it accordingly.

• If your driver specifies a PortDiscovery implementation, such as LumentumRoadmDeviceDescription.java the Snmp southbound provider also queries the description you provide and the ports that are available on that device and updates the information in the ONOS core. 

  So if your run in ONOS the command:

  Code Block
  onos> ports

  should return, among other devices also something like:

  Code Block

  onos> id=snmp:127.0.0.1:1, available=true, role=MASTER, type=SWITCH, mfr=unknown, hw=unknown, sw=unknown, serial=unknown, ipaddress=127.0.0.1, driver=lumentum, name=snmp:127.0.0.1:1 port=4, state=enabled, type=och, signalType=ODU4, isTunable=yes , name=1.1 port=5, state=enabled, type=och, signalType=ODU4, isTunable=yes , name=1.2 port=20, state=enabled, type=oduclt, signalType=CLT_100GBE , name=5 port=24, state=enabled, type=oduclt, signalType=CLT_100GBE , name=6 port=28, state=enabled, type=oduclt, signalType=CLT_100GBE , name=7 port=32, state=enabled, type=oduclt, signalType=CLT_100GBE , name=8 port=48, state=enabled, type=och, signalType=ODU4, isTunable=yes , name=12.1 port=49, state=enabled, type=och, signalType=ODU4, isTunable=yes , name=12.2

• Once the device is present in ONOS you can interact with it via the driver/provider subsystem.
