About the Tunnels Tab

On the Tunnels tab of the network table (Observability > Network > Topology > Tunnels), you can view the information on label-switched paths (LSPs), also known as tunnels, in your network.

Paragon Automation uses Path Computation Element Protocol (PCEP) sessions to discover the tunnels that run in your network.

Note: For Paragon Automation to discover tunnels in your network:
  1. A PCEP session must be established between Paragon Automation and the devices.

    To establish a PCEP session, you must specify a VIP address either at the time of installing Paragon Automation or post-installation of the cluster. For more information, see Configure a PCE Server.

    To establish PCEP on a PE router, see Configuring PCEP on a PE Router.

    To configure BGP-LS topology acquisition on Paragon Automation, See Configuring Topology Acquisition Using BGP-LS.

  2. You must have adopted or onboarded the device using Paragon Automation; otherwise, the tunnel-related information is not displayed on the Tunnels tab.

Tasks You Can Perform

  • Hide unrelated nodes of a tunnel—To hide unrelated nodes of a tunnel, select one or more tunnels and enable the Hide unrelated toggle button. The topology map limits the display to only the nodes that are related to the selected tunnel.

  • Provision a tunnel—Click Provisioning and select Tunnel to provision a tunnel. For more information, see Add a Tunnel.

    Note:

    Only Path Computation Element Protocol (PCEP) provision method is supported.

  • View historical data—Paragon Automation enables you can view the historical data. Historical data provides you valuable insights to past trends and patterns.

    Note:

    For Paragon Automation to collect historical data, you need to do the following:

    1. Enable traffic engineering while creating a device profile. For more information, see Add a Device Profile

      .
    2. Enable dynamic topology so that you can view real-time changes in your network. For more information, see Dynamic Topology Workflow.

    You can view the historical data for tunnel traffic. To view traffic and bandwidth for a tunnel in graphical form, select the tunnel and click Tunnel Traffic. In the Tunnel Traffic page that appears, select the period for which you want to view the data. You can view data for the previous 3 hours, the previous day, the previous week, or choose from a custom time range by specifying the start and end dates and the time.

    You can choose to auto refresh the data or manually refresh the data.

    Note:

    You can view the tunnel traffic if the device has Junos OS Release 22.X or later releases.

    If you are using ACX Series device, then you can view tunnel traffic only if you have installed Junos OS Evolved Release 23.4R2-S2.1.

  • Download—To download tunnels-related data to your local system, click Download. The data is downloaded to your local system as a comma-separated values (CSV) file.

  • From the More list, you can perform the following tasks:

    • View details of a tunnel—To view the details of a tunnel, you can do one of the following:

      • Select a tunnel on the table and click More > Show Details. The Tunnel - Tunnel-Name page appears. You can view the To and From traffic-related information.

      • Hover over a tunnel row in the table and click the Details icon. The Tunnel - Tunnel-Name page appears. You can view the To and From traffic-related information.

    • Reload—To view the latest changes in the network map, click Reload.

  • To perform common actions such as filtering using advanced filter criteria and resetting preferences, see Network Table Overview.
