Release Information

Statement introduced in Junos OS Releases 15.1F6 and 17.1R1.


Create a logical association between the specified IPLC base module and IPLC expansion module. The IPLC base module can accept and multiplex (add) and demultiplex (drop) up to 32 individual wavelengths into a single fiber pair. If you require the IPLC to support more than 32 channels, you can configure it to support an additional 32 channels by installing and connecting the IPLC expansion module to the IPLC base module, thus increasing the IPLC channel capacity to 64 channels.

Use this statement in combination with attaching the IPLC base and expansion modules together through the front panel as follows:

  • Install the IPLC base module and IPLC expansion module in the chassis.

    Best Practice

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

  • Connect the two IPLC modules together as follows:

    • Connect the XPN IN port of the IPLC base module to the XPN OUT of the IPLC expansion module.

    • Connect the XPN OUT port of the IPLC base module to the XPN IN of the IPLC expansion module.

    For complete details on making these connections on the PTX3000 Packet Transport Router, see the PTX3000 Hardware Guide.
