Monitoring the Service Summary Details of E-LAN Services for Optimal Debugging


You can view the Service Summary page of a particular service to display the consolidated and cumulative status of a service. The overall information pertaining to the service that you can obtain from the different widgets displayed on this page enables you to navigate to the appropriate device or service settings page and modify the configuration parameters appropriately. You can view the connection between the different endpoints and also examine the statistics on the packets and bytes traversering through the endpoints. Using the Service Summary page, you can also select the source device for which you want to view the transport metrics and the traffic statistics on the other pages displayed in Monitor mode for the specific service. This page enables you to obtain an effective graphical view in the form of tables of statistics and charts to view the health and performance of devices and services in your network, which enables you to analyze and troubleshoot the parameters that are causing traffic-handling errors.


The values and statuses of the parameters displayed in the graphs and tables of different widgets are refreshed, based on the polling interval configured on the Monitoring tab of the Preferences page (accessible by clicking the down arrow beside the System button on the Connectivity Services Director banner and selecting Preferences).

To view the Service Summary page for E-LAN services:

  1. Select Service View from the View Selector.

    The workspaces that are applicable to routing and tunneling services are displayed on the View pane.
  2. From the Junos Space user interface, click the Monitor icon on the Connectivity Services Director banner.

    The functionalities that you can configure in this mode are displayed on the task pane.
  3. From the Service View pane, on the left, click the plus sign (+) next to Network Services to expand the tree and display the different service types that you can configure.

    The Network Services tree is expanded and displayed on the View pane.

  4. Click the plus sign (+) beside Connectivity to view services based on protocols.

    The Connectivity tree is expanded and displayed on the View pane.

  5. Expand the E-LAN Services tree to select an E-LAN service.
  6. Click the ServiceSummary tab. The Service Summary page is displayed.

The Service Monitoring Summary page is displayed, if you do not select a particular service from the Service View pane and select the E-LAN Services term in the Service View pane. The Summary page displays a consolidated view of all of the service instances for a particular service type. The customer associated with the service, type of service, service definition upon which the service order is based, the traffic rate in bits per second, and the traffic trend are displayed. Select the corresponding service from the Network Services > Connectivity tree on the View pane to navigate to the Service Summary page.

The following widgets or widgets are displayed under this tab for E-LAN services. These statistical counters and metrics enable you to view an agglomerative, cohesive snapshot of the service configured on a device.

Service Status

This widget displays the cumulative, consolidated status of services, such as E-LAN. The following fields are displayed in a tabular form in this widget:

  • Name—Name of the service.

  • Type—Protocol configured for the service, such as E-Line, E-LAN, or IP.

  • Status—Whether the service is up or down. A green up-arrow in the indicates that the adjoining device in the network path to the destination device is operationally up. A red down-arrow indicates that the device is down.

  • PEs (Up/Down)—Number of provider edge devices that are in the up and down states

  • UNIs (Up/Down)—Number of user-to-network (ingress) interfaces that are in the up and down states

  • Local Switch—Whether the local switching mode to terminate multiple Layer 2 circuit pseudowires is configured

  • Y1731 Status—Whether the connectivity fault management (CFM) profile is configured for the service and whether performance monitoring (PM) statistics collection, such as one-way delay measurement and variation, two-way delay measurement and variation, or loss measurement are configured.

Click Refresh at the top of the monitor to update and display the contents of the table.


This monitor shows the status of connections between peer devices. In the tabular view, the row represents the source device and the columns denote the neighboring and destination devices. This monitor is applicable for E-LAN services.

One of the following values is displayed on the columns that denote the adjacent and destination devices or endpoints:

  • PR—Peer Device. Primary-Backup Pair. No Connection such as A/A or Z/Z.

  • PBK—Peer Backup. No Connection.

  • OL—No advertisement has been received for this virtual circuit from the neighbor. There is no outgoing label available for use by this virtual circuit.

  • NA—Not available.

Mouse over the cells in the table to display the description of the connection statuses, such as PR, PBK or NA.

For the device for which the connection status is displayed, a hyphen (-) is displayed under its own corresponding column to denote that it is not applicable. Click Refresh at the top of the monitor to update and display the contents of the table.

Traffic Summary

This widget displays the total number of egress packets (packets that are sent out) or traffic passing through all the UNI or customer-edge (CE) interfaces associated with the particular service. This monitor is valid for E-LAN services. The date and time at which the page was last updated is shown. A line graph is displayed with time on the horizontal axis and the number of output packets on the vertical axis.

From the Time Interval drop-down box, select 1 Hour, 8 Hours, 1 Day, 1 Week, 1 Month, 3 Months, 6 Months, 1 Year, or Custom to specify the duration for which the data polled from devices needs to be displayed. If you select the Custom option, the Time range popup dialog box is displayed. Specify the date from the calendar, and select the Time From (Start time in the 24-hour time format of collection of data), and Time To (End time in the 24-hour time format of collection of data). Click OK to save the settings. Else, click Cancel to discard the configuration.
