Understanding How to Configure the Integrated Photonic Line Card

 

This topic describes the basic configuration process for the IPLC modules and includes the following sections:

Understanding the Front Panel Connections

The IPLC base module and expansion module are slide-in cards that each occupy a single slot within the PTX3000 chassis. Unlike line cards, the IPLC does not connect into the high-speed data backplane of the chassis, but rather provides the following optical functions that you connect through the front panel:

  • Line IN and Line OUT ports—An input and an output port to connect to the optical line system, such as the optical ILA, or to another IPLC module.

  • PT IN and PT OUT ports—An input and an output port to connect to another IPLC base module. You can use these ports to connect two IPLC base modules together to form a two-degree node.

  • XPN IN and XPN OUT ports—An input and an output port to connect to an IPLC expansion module.

  • ADD and DROP ports—A total of 32 pairs of ports (32 ADD ports and 32 DROP ports) for 32 DWDM channels on the IPLC base module. The optional expansion module doubles the number of ADD and DROP ports to 64 ports, labeled 32 through 63 on the front panel.

    The IPLC modules are designed to connect the ADD and DROP ports on the front panel to compatible DWDM PICs in the same chassis, or to PICs or MICs in a remote chassis. PTX Series IPLC Compatibility provides a complete list of the PICs and MICs that are compatible with the IPLC ports.

Recommended Slot Placement

To minimize slot requirements and maximize shelf capacity, each IPLC module requires only a single FPC or PIC slot. These slot requirements are especially important if you are configuring a two-degree node or increasing the channel capacity to 64 channels.

Best Practice

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

Understanding How to Configure Wavelengths on the IPLC Ports

The WSS on the IPLC base module controls all port wavelengths, which you configure on a wavelength-by-wavelength basis. IPLC port mapping is fixed to a specific wavelength and frequency; each port accepts a single, preset wavelength depending on whether the port is located on the IPLC base module or expansion module. For a complete list of IPLC port mapping, see wavelength (IPLC).

Understanding How to Configure the Wavelength Operational Mode

The IPLC supports three possible modes of operation for IPLC wavelengths on the add and drop ports as follows:

  • blocked—(Default) If there is no explicit configuration for the IPLC wavelength, the wavelength is in blocked mode.

  • switch—Switches the specified IPLC wavelength to an optical interface on the same or different chassis, including a remote chassis.

    To switch a wavelength to an optical interface on the same chassis, enter the following in the CLI:

    To switch a wavelength to an optical interface on a remote chassis, enter the following in the CLI:

    For complete details on switching a wavelength to an optical interface, see Configuring the Integrated Photonic Line Card to Switch Wavelengths to Local or Remote Optical Interfaces.

  • wss-express-in—Bypass the specified wavelength.

    For example, to bypass wavelength 1550.12 on the IPLC in slot 1:

    Note

    Bypassing wavelengths is supported only on IPLC two-degree nodes running express traffic. For more information, see Configuring a Two-Degree Node for Express Traffic.
