Example: Integrated Photonic Line Card in a Metro Linear Packet Optical Configuration
This example shows how to configure Junos OS to support the integrated photonic line card (IPLC) base modules in a Metro linear packet optical configuration.
Requirements
This example uses the following hardware and software components:
Four IPLC base modules
Compatible 10-Gigabit or 100-Gigabit Ethernet OTN PICs. For a list of compatible optical interfaces that are compatible with the IPLC ports, see PTX Series IPLC Compatibility.
Three PTX3000 Packet Transport Routers running Junos OS 15.1F6
For complete information on all PTX Series Packet Transport Routers hardware components, see PTX Series Packet Transport Routers.
For complete information on all PTX Series Packet Transport Routers software features, see Junos OS for PTX Series Packet Transport Routers, Release 15.1.
Overview
This examples describes how to configure Junos OS to support
IPLC base modules in a metro linear packet optical deployment. The Add and Drop ports of the IPLC modules
are physically connected to interfaces housed in the same PTX3000
chassis.
Topology
Figure 1 shows the configuration of the IPLC modules and interfaces for this example.
This procedure describes how to configure Junos OS for the IPLC modules. This is not a complete configuration and does not include full instructions for configuring the router or the associated line cards. Before you start this procedure, complete the following hardware and software tasks on the PTX3000 router:
Install the IPLC modules, associated line cards, and PICs into the PTX3000 chassis so that the hardware configuration matches what is shown in Figure 1. If you need to make changes to the positions of the cards in the chassis, adjust the FPC numbers referenced in Figure 1 and configure them accordingly.
Best Practice We recommend that you place the two IPLC modules at Node B into the same FPC/PIC slot pair on the PTX3000 chassis. In this example the IPLCs at Node B are located in FPC slots 2 and 3.
Configure the associated wavelengths on the interfaces of the PTX3000 by using the following procedure:
Specify the interface to configure.
[edit]user@host# edit interfaces interface-name]For example:
[edit]user@host# edit interfaces et-6/0/0]Specify the wavelength value supported on the interface.
[edit interfaces et-6/0/0]user@host# set wavelength
Note Be sure to specify wavelength values on each interface as shown in Figure 1. If you must adjust the wavelength values, make sure that you enter a value supported on the IPLC. For information on the wavelengths supported by the IPLC, see Understanding the Integrated Photonic Line Card Architecture.
Make all connections to and from the PICs in the PTX3000 chassis to the
AddandDropports on front panel of each IPLC node as shown in Figure 1.Connect your fiber pairs to the
Line INandLine OUTports on the front panel of each IPLC node as shown in Figure 1.For simplicity, Figure 1 does not show the optical ILAs between the three IPLC nodes.
On Node B, connect the two IPLC modules together using the
PT INandPT OUTports on the front panel of the IPLC as shown in Figure 1.
Anytime you need to disconnect or connect the
fiber span from the Line IN and Line
OUT ports on the IPLC module, we recommend you disable
the optical supervisory channel and the erbium-doped fiber amplifiers
on the IPLC.
Always refer to the PTX3000 Packet Transport Router Hardware Guide when connecting or disconnecting cables on the IPLC modules. See PTX3000 Packet Transport Router Hardware Guide.
This example results in the following configuration:
