Viewing a Graphical Image of the Optical Interface Components

The Chassis View provides a pictorial representation of the optical interface, optical channel data unit (ODU), optical channel transport unit (ODU) of an MX Series and PTX Series router, and the modules or components that are installed in it, such as the line cards, interfaces, and other hardware elements.

The purpose of this view is to try and provide a comprehensive monitoring view of the health and status of deployed devices across the network. In this view all the managed devices are shown with their appropriate status and health based on the services and device settings applied. This view helps the operator to know the health and status across the network, it provides with the operator to quickly see the macro level information, which allows the operator to further analyze the information provided and quickly navigate to individual devices and take any further corrective measure required. It provides a cohesive tool for the operator to quickly see the micro-level information and take any further remediation action required.

To view a graphical image of the optical interfaces, OTUs, and ODUs of MX Series and PTX Series routers, and its associated components:

  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 device for which you want to define the optical port 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. Click a particular component or interface to display the associated details in the lower portion of the page. The Rotate and Perspective buttons enable you to view the images in required orientation.
  6. Click the View Back (arrows in a square symbol) icon to cause the device image to rotate along the x-axis and display the rear view of the device. Alternatively, click the View Front icon to view the front plane of the device. The View Back and View Front icons are toggle options.
  7. Click the Perspective (cube symbol) icon to display the device image in three-dimensional format. It is a toggle button, which causes the device image to be shown in either three-dimensional or one-dimensional format.
  8. Select the level of magnification of the image by clicking the Zoom (magnifying glass) icon. The image is expanded and displayed.

    Alternatively, use the slider control beneath the Zoom icon to change the level of magnification.

  9. Click the home icon to return to the front view of the chassis.

    The selected interface is surrounded with a colored outline based on the operational status. An interface that is operationally up is denoted in green and an interface that is operationally down is represented in red. The components are depicted as small colored icons at the top-left corner of the front view of the equipment image.

You can mouse over the different parts of the graphical image of the device , such as the interfaces, line cards, and slots. When you mouse over the different modules, their corresponding details are displayed as tooltips. On clicking the device components, the corresponding description for the selected component is displayed by default in the Component Info pane and the Equipment tab.

  • Manufacturer—Name of the company that built and shipped the device.

  • Part number—Part number of the chassis component.

  • Serial number—Serial number of the chassis component. The serial number of the backplane is also the serial number of the router or switch chassis. Use this serial number when you need to contact Juniper Networks Customer Support about the router or switch chassis.

When you select any physical interface configured on the DPCs or PICs or MICs provisioned, the following fields are displayed for the corresponding component for each interface. The interface is surrounded by a colored box to show the Operational Status.

The Component Info pane and the Active Alarms monitor are displayed in the lower portion of the page.

The Active Alarms monitor shows any active alarm that has not yet been cleared. You can view the alarm name, the unique identifier assigned to the alarm, the person to which the alarm is assigned for corrective action, and the severity of the alarm. Click the Launch Alarm Mgmt icon (right upward-slanting arrow enclosed in a square) to navigate to the Fault mode and view the four standard alarm monitors available in Fault mode.

Active Alarms for the respective components are displayed when the component is clicked in the image of the chassis displayed. The components for which the alarms are displayed are Flexible Port Concentrator (FPC), Dense Port Concentrator (DPC), Physical Interface Card (PIC), Modular Interface Card (MIC), Routing Engine, Control Boards, fan trays, Switch Interface Board (SIB), and power supply module (PSM).

The following fields are displayed in the Active Alarms pane:

Configured textual description of the interface

A redundant Ethernet interface is a pseudointerface that includes at minimum one physical interface from each node of the cluster. A redundant Ethernet interface must contain, at minimum, a pair of Fast Ethernet interfaces or a pair of Gigabit Ethernet interfaces that are referred to as child interfaces of the redundant Ethernet interface (the redundant parent). If two or more child interfaces from each node are assigned to the redundant Ethernet interface, a redundant Ethernet interface link aggregation group must be formed.

A pseudowire subscriber logical interface terminates an MPLS pseudowire tunnel from an access node to the MX Series router that hosts subscriber management, and enables you to perform subscriber management services at the interface. Subscriber management supports the creation of subscriber interfaces over point-to-point MPLS pseudowires. The pseudowire subscriber interface capability enables service providers to extend an MPLS domain from the access-aggregation network to the service edge, where subscriber management is performed. Service providers can take advantage of MPLS capabilities such as failover, rerouting, and uniform MPLS label provisioning, while using a single pseudowire to service a large number of DHCP and PPPoE subscribers in the service network.


The pseudowire is a tunnel that is either an MPLS-based Layer 2 VPN or Layer 2 circuit. The pseudowire tunnel transports Ethernet encapsulated traffic from an access node (for example, a DSLAM or other aggregation device) to the MX Series router that hosts the subscriber management services. The termination of the pseudowire tunnel on the MX Series router is similar to a physical Ethernet termination, and is the point at which subscriber management functions are performed. A service provider can configure multiple pseudowires on a per-DSLAM basis and then provision support for a large number of subscribers on a specific pseudowire. Figure 1 shows an MPLS network that provides subscriber management support.

The following table describes the fields displayed in the Pseudo Interfaces pane.

Table 3: Pseudo Interfaces Columns
