Examples for Configuring Access Nodes

The OB-BAA distribution includes standard device adapters (SDA) for OLTs and DPUs along with a set of examples on how to configure those devices using a NETCONF client.

The examples described in this section of the document can be found in the resources/examples/dpu-config and resources/examples/olt-config directories of the OB-BAA source code distribution.

The BAA layers NAI uses standard's based YANG models for configuring the Access Nodes.

For configuration of OLTs and DPUs the following YANG modules are important:

• TR-355 - YANG Modules for FTTdp Management
• TR-383 - Common YANG Modules for Access Network
• TR-385 - ITU-T PON YANG Modules

DPU Configuration

The DPU configuration examples are located in resources/examples/dpu-config and consist on the following steps:

1. Create a DPU using the DPU SDA

2. Add interfaces

3. Configure N:1 services

4. Configure 1:1 services

5. Configure and apply G.fast profiles

The following figure summarizes the VLAN operations configured in step 3 and 4:

Legend:

• sub itf - TR-383 sub-interface

• fwd - TR-383 forwarder

  Info: the forwarder ports were omitted since they have a 1:1 relationship to the sub-interface

• ptm - Packet Transfer Mode Interface

• dsl - DSL interface

OLT Configuration

The OLT configuration examples are located in resources/examples/olt-config.

This section of the documents provides a examples of how to configure the OLT using either:

• 1:1 Services: Each ONU LAN sub-interface has a corresponding OLT WAN sub-interface

• N:1 Services: Multiple ONU LAN sub-interfaces use the same OLT WAN sub-interface

Configure OLT for 1:1 Services

The first OLT configuration example consists on the following steps:

1. Create an OLT using the OLT SDA

2. Add the OLT and ONU interfaces. This includes the vANI and OLT-vENET interfaces. Please refer to TR-385 for additional information.

3. Populate the TR-385 link table

4. Create TR-383 QoS Classifiers

5. Create TR-383 sub-interfaces on the ONT ports

6. Create GEM ports and T-CONTs

7. Configure a 1:1 services

The following figure summarizes the operations configured in step 5,6 and 7:

Legend:

• sub itf - TR-383 sub-interface

• fwd - TR-383 Forwarder. Note: the forwarder ports were omitted since they have a 1:1 relationship to the sub-interface

• eth - Ethernet Interface

Configure OLT for N:1 services

The second OLT configuration example consists on the following steps:

1. Create an OLT using the standard OLT adapter

2. Add the OLT and ONU interfaces. This includes the vANI and OLT-vENET interfaces. Please refer to TR-385 for additional information.

3. Populate the TR-385 link table.

4. Create TR-383 QoS Classifiers

5. Create TR-383 sub-interfaces on the ONT ports

6. Create GEM ports and T-CONTs

7. Configure a N:1 service

The following figure summarizes the operations configured in step 5,6 and 7:

Legend:

• sub itf - TR-383 sub-interface

• fwd - TR-383 Forwarder

  Info: the forwarder ports were omitted since they have a 1:1 relationship to the sub-interface

• eth - Ethernet interface

Performance collection configuration

An example for configuring an IPFIX exporting process on an access node is provided in resources/examples/requests/ipfix-configuration-example.xml. To run the example, it is assumed that a device named deviceA with an interface called eth0 is already created.
