Configuring Optical IPLC Line Connectivity for Interoperation with Optical ILAs

Each optical inline amplifier (ILA) is connected to other optical ILAs or optical integrated photonic line cards (IPLCs) using optical ports or optical supervisory channels (OSCs). There are two optical ports for each optical ILA, designated as OSC A and OSC B. For IP connectivity over OSC, the optical IPLC is used as a gateway. There is no direct IP connectivity between the optical ILA and external servers.

An optical IPLC is a standalone appliance in PTX3000 routers, running Linux. It has host path connectivity to the PTX3000 Routing Engine and other FPCs in the chassis (over internal routing instance). It does not have any router interfaces or switch fabric connectivity; therefore, there is no data path connectivity to other FPC interfaces. The optical IPLC software responds to SNMP commands from the network management server (NMS). SNMP commands are received by the transport daemon (transportd) running on the Routing Engine and are relayed to the optical IPLC CPU running the transport process. For providing IP connectivity, all optical IPLC and optical ILA in the chain are considered to be over a LAN.

Because all communication to an optical ILA is through an optical IPLC, one of the optical IPLCs in the chain is designated as the anchor IPLC. All optical ILA commands are directed to the anchor IPLC (which denotes the FPC slot number of the optical IPLC on a specific router) with a parameter indicating the optical ILA identity (OSC management IP address or the serial number). The anchor IPLC maintains a table of IP addresses for all optical ILA OSC-management ports (along with the optical ILA identifier) in the chain. This table is created through the optical IPLC CLI. The IPLC software forwards the commands to the required optical ILA. Each optical ILA in the chain also contains the anchor optical IPLC configuration. This optical ILA is used to send periodic updates and traps.

To configure connectivity between an optical IPLC and an optical ILA on a PTX3000 router:

  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. The Equipment, Status/Config, Performance, and Line Connectivity tabs are displayed at the bottom of the dialog box.

  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. Click the Line Connectivity tab at the bottom of the dialog box.

    The IPLC Line Connectivity dialog box is displayed on the right pane with the configuration settings that can be used to establish a link between the optical IPLC and an optical ILA. You can establish the connectivity between a particular IPLC and optical ILAs that exist on the same PTX3000 router chassis using the fields in the dialog box.

  8. In the TE Id field, enter the traffic engineering (TE) unique identifier that you want to use for the connectivity between the optical IPLC and optical ILA.

    By default, this field is prepopulated with the IETF-TE-Topology value as the identifier for the topology Information about the IPLC module installed in the FPC or PIC slot. You can modify this value as needed.

  9. In the Provider Id field, specify the unique identifier of the provider or the originating module, which is the IPLC in this case.

    By default, this field is prepopulated with 1. You can modify this value as needed.

  10. In the Client Id field, specify the unique identifier of the client or the receiving module, which is the optical ILA in this case.

    By default, this field is prepopulated with 1. You can modify this value as needed.

  11. In the A End IPLC field, click Select beside the field to select the endpoint or destination IPLC with which the connection must be established.

    The Choose IPLC dialog box is displayed. The dialog box contains two panes. The top pane lists all the routers that are present in the network, and the bottom pane lists all the optical IPLCs that reside on the router chassis that you select in the top pane. You can sort and filter the displayed routers by entering a match criterion, such as the router name, in the search field, and click the Search icon in both the top and bottom panes. Table 1 describes the fields displayed in the top pane of the Choose IPLC dialog box. Table 2 describes the fields displayed in the bottom pane of the Choose IPLC dialog box.

      You are returned to the IPLC Line Connectivity dialog box. The router name and the IPLC name are displayed in the two text fields, respectively, beside the Z End IPLC field.

    In the Z End IPLC field, the PTX3000 router name on which the IPLC for which you are configuring line connectivity resides is displayed in the first field. The IPLC name, which is the same as the one for which you are configuring settings, is displayed in the second field. The Select button is displayed beside these text fields.

  12. In the ILA Connections section, do the following:

    1. Click the ILA (A -> Z) tab.

    5. Select an optical ILA from the table, and click Remove to delete any ILA that you do not want to participate in the IPLC connectivity chain.

      You are not prompted to confirm the deletion. You can readd the optical ILAs as necessary to the connectivity chain.

    6. Click the Interface Matrix tab.

      The wavelengths configured for the A and Z end interfaces are displayed. The following fields are displayed in a table:

      • Wavelength—All the available wavelengths supported by the PTX3000 router

      • A End Interfaces—Optical interface name with the FPC, PIC, and port number of the A end or source interface

      • Z End Interfaces—Optical interface name with the FPC, PIC, and port number of the Z end or the destination end of the connection. The Z end interface is an optical interface to which the IPLC is connected (for switch mode) or the IPLC expansion module to which the IPLC base module is connected (for express-in mode).

      All port wavelength frequencies are controlled by the wavelength selective switch (WSS of the IPLC) and configured on a wavelength-by-wavelength basis. The mapping for the wavelengths, frequencies, and ports is fixed. Each port is assigned a specific frequency and wavelength depending on whether the port is on the IPLC base module or expansion module.

  13. Click Add/Update at the top of the IPLC Line Connectivity dialog box to save the connection settings between the optical IPLC and optical ILAs that you specified.

  14. Click Graphical View at the top of the IPLC Line Connectivity dialog box to view the connection between the source IPLC and the destination IPLC through the specified optical ILAs in the chain in a pictorial form.

    The Line Connectivity Details dialog box is displayed, with the source and destination PTX3000 router chassis displayed. Green connector lines are shown to indicate the link between the source and destination routers. IPLC and optical ILA IP addresses are displayed above the green connector lines. Click OK when you have completed viewing the graphical representation of the connectivity.

  15. (Optional) Click Delete at the top of the dialog box to delete the connectivity you created for the IPLC.

    A job is created and run to delete IPLC line connectivity. The Delete IPLC Line Connectivity dialog box is displayed after the job is completed, with the job name, start and end times of the job, job status, and summary. Click Close to close the job dialog box.

    You can click Refresh to update the contents of the dialog box.


Alternatively, click Cancel if you want to discard the configured IPLC line connectivity settings. You can click the Refresh (rotating arrow icon) button at the top of the dialog box to enable the latest settings be retrieved from the device and displayed.
