    Viewing Performance Monitoring Details of Optical ILAs for Detecting and Diagnosing Faults

    To analyze and resolve any faults associated with optical inline amplifiers (ILAs), it is essential to view the diagnostic data, warnings, and alarms for transport performance monitoring. The different types of parameters related to performance monitoring that are retrieved from the optical ILAs enable you to ensure service availability and verify or monitor individual services and the service network performance.

    The performance monitoring capability in Connectivity Services Director displays information about the health of your network and changing conditions of your optical ILAs. Use this diagnosis and detection mechanism to identify problems with the equipment, pinpoint security attacks, or to analyze trends and categories of errors. This feature includes fault-monitoring details in the dashboard, in monitoring pages, and on a dedicated page that displays alarms, events, and system log messages that are generated. Performance monitoring parameters can be viewed in both chart and statistical formats. These charts and statistical details provide essential and cohesive information about system conditions, any discrepancies and malfunctioning, and protocols or components that need to be examined and debugged for better efficiency and working capacity. You can assess the performance of your network, not only at a point in time, but also over a period of time. This feature enables you to determine trending and network-health parameters; for example, whether service-level agreements (SLAs) have been violated.

    To view the performance monitoring details of optical ILAs:

    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 ILA 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. Select an optical ILA in the image of the device.

      The ILA Optics dialog box is displayed at the lower part of the page, which contains the Equipment, Status/Config, and Performance tabs.

    6. Click the Performance tab at the bottom of the pane.

      This pane contains the Perf Mon and TCA Config tabs. The Perf Mon tab of the ILA Optics PMs dialog box is displayed s shown in Figure 1.

      The following fields are displayed in the Perf Mon tab of the ILA Optics PMs dialog box. The date and time at which the dialog box was last refreshed is shown.

      Note: Pump Turn-Down During a Loss of Signal— If LOS (Loss of Signal) is detected based on lack of receipt of the OSC signal at the input port of an amplifier, then the amplifier must turn down its pumps (to achieve no more than 0dBm total output power), until it detects receipt of a valid OSC signal at its input port. Likewise, if an upstream amplifier receives an OSC message from the downstream node that the OSC signal was not received downstream (LOS was declared downstream), it must also turn down its own pumps (to achieve no more than 0dBm total output power) until it receives an OSC message that the fault has cleared. Therefore, in addition to the automatic power reduction (APR) algorithm, the ILA software must keep the amplifier pumps disabled until a fiber connection is confirmed between the ILA output port and the input to the downstream optical node. This fiber connection is confirmed using the “handshaking” messages exchanged over Optical Supervisor Chanel (OSC). This behavior occurs during amplifier turn-up and during ongoing operation.

      Local LOS—The software reads the LOS status for incoming signal from SFP. This LOS status can be used to shut off the amplifier pump. When local LOS is cleared, pumps need to be turned on again.

      Remote LOS—Incoming LOS status is conveyed to OSC_FPGA. OSC_FPGA in turn sends this status to nextnode through some overhead bits. The next node OSC_FPGA would read the overhead bits and puts it in its “Remote LOS” register. OSC_FPGA also forwards the remote LOS status further down the chain through overhead bits in the same way. The software can read the “Remote LOS” value and take appropriate action of turning the amplifier pump on or off.
