About the Demand Tab

Use the Demand tab to view aggregated demands that are generated based on the flow monitored by the NetFlow collector.

To access this tab, select Network > Topology and hover over the More list (next to the Tunnel tab) and select Demand.

Tasks You Can Perform

  • View the routing path for a demand—Select a demand in the network information table for the corresponding routing path to be highlighted in the topology map.


    Currently, you can preview paths on the topology map only for RSVP LSPs (not for segment-routed LSPs).

  • View demand traffic—To view demand traffic over a period of time in graphical form, select a demand and click View Demand Traffic. In the Demand Traffic page that appears, select the period for which you want to view the data. You can view data for the past 5 minutes, 10 minutes, 1 hour, 3 hours, the previous day, the previous week, or choose from a custom time range by specifying the start and end dates (in MM/DD/YY format) and times (in HH:MM AM/PM 12-hour format) in the Choose Time Range page that appears.

    You can click the refresh icon so that the page refreshes to display the most recent data. Alternatively, you can enable the Auto Refresh toggle button and select the interval (10 seconds, 30 seconds, 1 minute, or 5 minutes) after which the page must refresh automatically to display the latest data.

  • Download details of all the demands—To view detailed information of all the demands displayed in the network information table, click Download. You can choose to open the comma-separated values (CSV) file with Excel or other applications, or save the file to your local system.
  • From the More list, you can perform the following tasks:
    • View details of a demand—To view details of a demand, select the demand and click Show Detail. Alternatively, hover over a demand and click the details icon that appears. You can also right-click on a demand and select Show Detail.

      The Demand-Demand Name page appears, displaying the details, such as live properties, planned properties, and operational status of the demand.

    • Provision multiple tunnels—To add multiple tunnels pertaining to a demand, select a demand and click Provision Multiple Tunnels. Alternatively, right-click on a demand and select Provision Multiple Tunnels.

      The Provision Multiple Tunnels page appears, with some parameters pertaining to traffic flow (such as Node A and Node Z) pre-populated from the selected demand. You can modify the parameters as required, and provision the tunnels. See Add Multiple Tunnels.

    • Reload the network information table—To download updated demand data to your Web browser, click Reload. A REST API query is sent to the Paragon Automation server and then, the network information table is updated.

  • Delete one or more demands—Even when a flow is no longer observed, the demand is retained and displayed in the Demand tab until you delete it. To delete such demands manually, select one or more demands and click the delete (trash can) icon. The selected demands are deleted.

    Alternatively, you can add a Demand Aging task to automate the deletion. See Add a Demand Aging Task.
