R-CORD Configuration

Once all the components needed for the R-CORD profile are up and running on your POD, you will need to configure it. This is typically done using TOSCA. This configuration is environment specific, so you will need to create your own, but the following can serve as a reference:

tosca_definitions_version: tosca_simple_yaml_1_0
imports:
  - custom_types/oltdevice.yaml
  - custom_types/switch.yaml
  - custom_types/switchport.yaml
  - custom_types/portinterface.yaml
  - custom_types/voltservice.yaml
  - custom_types/vrouterserviceinstance.yaml
  - custom_types/vrouterstaticroute.yaml

Top-Down Subscriber Provisioning

Once the POD has been configured, you can create a subscriber. This section describes a "top-down" approach for doing that. (The following section describes an alternative, "bottom up" approach.)

To create a subscriber, you need to retrieve some information:

• ONU Serial Number
• Mac Address
• IP Address

Find ONU Serial Number

Once your POD is set up and the OLT has been pushed and activated in VOLTHA, XOS will discover the ONUs available in the system.

You can find them through:

• XOS GUI: on the left side click on vOLT > ONUDevices
• XOS Rest API: http://<pod-id>:<chameleon-port|30006>/xosapi/v1/volt/onudevices
• VOLTHA CLI: Command Line Interface

If you are connected to the VOLTHA CLI you can use the following command to list all the existing devices:

(voltha) devices
Devices:
+------------------+--------------+------+------------------+-------------+-------------+----------------+----------------+------------------+----------+-------------------------+----------------------+------------------------------+
|               id |         type | root |        parent_id | admin_state | oper_status | connect_status | parent_port_no |    host_and_port | vendor_id| proxy_address.device_id | proxy_address.onu_id | proxy_address.onu_session_id |
+------------------+--------------+------+------------------+-------------+-------------+----------------+----------------+------------------+----------+-------------------------+----------------------+------------------------------+

+------------------+--------------+------+------------------+-------------+-------------+----------------+----------------+------------------+----------+-------------------------+----------------------+------------------------------+

Locate the correct ONU, then:

(voltha) device 00015698e67dc060
(device 00015698e67dc060) show
Device 00015698e67dc060

+------------------------------+------------------+
|                  flows.items |        5 item(s) |
+------------------------------+------------------+

to find the correct serial number.

Push a Subscriber into CORD

Once you have this information, you can create the subscriber by customizing the following TOSCA and passing it into the POD:

tosca_definitions_version: tosca_simple_yaml_1_0
imports:
  - custom_types/rcordsubscriber.yaml
description: Create a test subscriber
topology_template:
  node_templates:
    # A subscriber
    my_house:
      type: tosca.nodes.RCORDSubscriber
      properties:
        name: My House
        c_tag: 111
        onu_device: BRCM1234 # Serial Number of the ONU Device to which this subscriber is connected
        mac_address: 00:AA:00:00:00:01 # subscriber mac address
        ip_address: 10.8.2.1 # subscriber IP

For instructions on how to push TOSCA into a CORD POD, please refer to this guide.
