Example: Configuring the Optical Supervisory Channel for the Integrated Photonic Line System and Optical Inline Amplifier

 

This example shows you how to configure optical supervisory channel (OSC) communication across the PTX3000 integrated photonic line system when you are using the Juniper Networks optical ILA in the amplifier chain.

Requirements

This example uses the following hardware and software components:

  • Two PTX3000 Packet Transport Routers with the Integrated Photonic Line System installed and running Junos OS Release 17.1 or later.

  • Three optical inline amplifiers.

Before you configure the optical supervisory channel, be sure you have:

  • Installed and configured the integrated photonic line system in the PTX3000 router and that you are able to pass optical traffic end to end over the three optical ILAs.

Overview

This example shows you how to configure optical supervisory channel (OSC) communications on the PTX3000 integrated photonic line system when using the optical ILA in the amplifier chain.

Topology

Figure 1 shows the topology for this example. At Site A, there is a PTX3000 router with an IPLC module installed in FPC slot 3. The IPLC module at Site A is the anchor for the OSC. Three optical inline amplifiers configured as: ILA 0, ILA 1, and ILA 2 connect Site A to Site B, where another PTX3000 is running an IPLC module. The IPLC module at Site B is specifically configured as a non-anchor IPLC.

This topology also includes an example of configuring threshold crossing alerts (TCA)s on the optical ILAs through the Junos OS CLI on the PTX3000 at Site A.

For this example, it is irrelevant what optical signals you are passing over the line system. However, the line system must be up and operational.

Configuration

To configure OSC communication for the PTX3000 integrated photonic line system and optical ILAs in the amplifier chain, perform these tasks:

CLI Quick Configuration

To quickly configure this example, copy the following commands, paste them into a text file, remove any line breaks, change any details necessary to match your network configuration, and then copy and paste the commands into the CLI at the [edit] hierarchy level.

Step-by-Step Procedure

The following example requires that you navigate various levels in the configuration hierarchy. For information about navigating the CLI, see “Using the CLI Editor in Configuration Mode” in the CLI User Guide.

To configure the PTX3000 integrated photonic line system at Site A and the optical ILAs in the amplifier chain:

  1. Configure the anchor IPLC.
  2. Configure optical ILA 0.
  3. Configure optical ILA 1.
  4. Configure optical ILA 2.
  5. Verify the configuration is correct.
  6. If the configuration is correct, save it.

  2. Verify the configuration is correct.
  3. If the configuration is correct, save it.

Verification

Confirm the configuration is working properly.

Verifying the Topology of the Amplifier Chain

Purpose

Display the IPLC and optical ILA basic information for the complete amplifier chain including the •

Display the IP addresses, names, reachability, and connection status for the anchor IPLC

  • Anchor IPLC and OSC IP address

  • Optical ILA name, OSC IP address/IP mask, status: Up/Down, and where the optical ILA is connected to from IPLC’s perspective

Action

On the PTX 3000 at Site A, from operational mode, run the show chassis fpc optical-properties amplifier-topology command to display the OSC topology for the amplifier chain.

user@host> show chassis fpc optical-properties amplifier-topology fpc-slot 3

On the PTX 3000 at Site B, from operational mode, run the show chassis fpc optical-properties amplifier-topology command to display the OSC topology for the amplifier chain.

user@host> show chassis fpc optical-properties amplifier-topology fpc-slot 3

Meaning

The output shows the correct topology based on Figure 1. In addition, all optical ILAs show are reachable indicating OSC communications are functioning properly.
