Configuring a Two-Degree IPLC Node for Express Traffic by Increasing the Line Capacity

For metro linear and metro ring topologies that require either north-south or east-west communications, you can connect two IPLC base modules together to form a two-degree IPLC node. This enables you to run express traffic in two directions. This topic describes how to setup and configure an IPLC two-degree node.

Using the express-in software capability of the IPLC, you can configure the IPLC to accept a wavelength from another IPLC residing in the same chassis. For example, when you have configured an IPLC node using two IPLC base modules. This topic describes how to express-in a wavelength from one IPLC to another IPLC within the same chassis.

Before you begin, complete the following tasks:

  • Install and connect the two IPLC base modules through the PT IN and PT OUT ports. These two IPLC modules form the two-line IPLC node.

    Best Practice:

    We recommend that you place the IPLC modules into the same FPC or PIC slot pair on the PTX3000 chassis.

To configure the IPLC for two-line terminations to express-in a wavelength from another IPLC:

  1. From the Junos Space user interface, click the Build icon on the Connectivity Services Director banner.

    The workspaces that are applicable to Build mode are displayed on the Tasks pane.

  2. From the View selector, select Device View.

    The functionalities that you can configure in this view are displayed.

  3. From the Device View pane, click the plus sign (+) next to the My Network tree to expand the tree and select the PTX300 router for which you want to define the optical IPLC settings.

    The network tree is expanded and the selected device is highlighted.

  4. From the Tasks pane, select Device Management > View Physical Inventory.

    An image of the device is displayed on the right pane.

  5. In the image of the device, select an optical IPLC—for example, an optical IPLC installed in a PTX3000 router.

    The Component Info dialog box is displayed. At the lower part of the dialog box, the Equipment, Status/Config, Performance, and Line Connectivity tabs are displayed.

  6. Click the Status/Config tab at the bottom of the dialog box.

    The IPLC Line dialog box is displayed on the right pane with the configuration settings that pertain to the IPLC.

  7. Specify the FPC or PIC slot in which the IPLC base module resides by selecting the slot in the Chassis View.

    For example, if the IPLC base module resides in slot 1, select the IPLC 1 component in the image of the chassis.

  8. Create a logical association between the two IPLC modules and specify that you want the IPLC to express-in a wavelength.

    For example, if the other IPLC resides in slot 2, select IPLC 2 from the Express IPLC list in the Settings/Status section.

  9. Configure the wavelength supported by the OTN transponder and make sure it is supported by the IPLC base module.

    For example, to configure the wavelength as 1532.29, select the Show All Wavelengths check box, and select express from the drop-down menu in the configuration column of the table for the corresponding wavelength.

  10. Click Update to save the specified configuration settings.
