Step 1: Begin

In this guide, we provide a simple, three-step path, to quickly get you up and running with the Juniper Support Insight (JSI) solution. We’ve simplified and shortened the installation and configuration steps.

Meet Juniper Support Insights

Juniper® Support Insights (JSI) is a cloud-based support solution that gives IT and network operations teams operational insights into their networks. JSI aims to transform the customer support experience by providing Juniper and its customers with insights that help improve the network performance and uptime. JSI collects data from Junos OS-based devices on customer networks, correlates it with Juniper-specific knowledge (such as service contract status, and End of Life and End of Support states), and then curates that into actionable insights.

Virtual Lightweight Collector

The Virtual Lightweight Collector (vLWC) is a VMWare-ready data collection tool that gathers operational data from Juniper devices on customer networks. JSI uses this data to provide IT and network operations teams with actionable operational insights into the onboarded Juniper devices on customer networks. The vLWC uses your existing VMWare infrastructure to provide a virtualized solution while offering the capabilities of the LWC.

At a high level, getting started with the JSI solution involves the following steps:

  1. Installing and configuring a Virtual Lightweight Collector (vLWC)

  2. Onboarding a set of Junos devices to JSI to initiate data collection

  3. Viewing notifications about device onboarding and data collection

  4. Viewing operational dashboards and reports


This Quick Start guide assumes that you have ordered the JSI-vLWC solution, which is available as part of Juniper Care support service, and that you have an active contract. If you have not ordered the solution, please contact your Juniper Account or Services teams. Accessing and using JSI is subject to the Juniper Purchase and License Agreement (JPLA). For general information on JSI, see Juniper Support Insights Datasheet.

Install and Configure the Virtual Lightweight Collector

In this guide, we show you how to install and configure the vLWC on a VMWare environment.

Before You Begin

To successfully install and deploy vLWC, you must meet the following requirements:

  • VMWare vCenter Server access (using VMWare vSphere Client, version 6.7.0 or later)

  • One of the following minimum hardware requirements:

    Configuration Type

    Total Devices Supported

    Number of vCPUs Memory Storage


    Up to 10,000 devices

    6 CPUs

    16 GB RAM

    400 GB disk space


    Up to 20,000 devices

    12 CPUs

    32 GB RAM

    400 GB disk space


    The vLWC can experience data collection issues if your system does not meet the minimum requirements. A lack of CPU and/or memory resources can cause the vLWC to go into a holding pattern and stop collecting data.

  • Three VM network interfaces:

    Connectivity Interface Name Description



    Internal network to access the Junos devices being monitored by JSI. This network should not have access to the Internet.



    External network with HTTP/HTTPS and DNS Internet connectivity to connect to Juniper Cloud directly or through an active proxy server.



    Connectivity to the management network host services:

    • Port 443/HTTPS for the Captive Portal web page

    • Port 22/SSH for the JSI shell


    While configuring the internal, external, and management interfaces, you must ensure that the subnet of the IP address assigned to the internal network port, external network port, and captive (management) portal are different from each other.

  • The vLWC software that is provided as a single downloadable OVA file. To download, visit the vLWC request page on Juniper Support Portal at, submit a form with the requested information, and receive a link over an email to download the vLWC software. Refer Download vLWC Software for more information.


    The OVA file will be created specifically for your installation. It contains your serial number as an encrypted vApp property that will be used during the initial boot process of the VM.

  • Support for VMXNET3 network adapters.

Here's how to install vLWC using the vCenter Server:

  1. Login to the vCenter Server using your username and password in the vSphere Client.
  2. Click Menu > Hosts and Clusters to open the Hosts and Clusters page.

    The Hosts and Clusters page lists all your data centers and vSphere clusters on the left pane.

  3. Right-click your data center and click Deploy OVF Template... from the Actions menu.

    The Deploy OVF Template page opens.

  4. Depending on where your OVA file is available, select the URL option and provide the URL to the OVA file, or select the Local file option and click Choose Files to browse the local drive and upload the vLWC OVA image. Click Next.

    The Select a name and folder page opens.

  5. Enter a unique name for the vLWC vApp. Select the data center where you want the vApp installed and click Next.
    The Select a compute resource page opens.
    The vLWC vApp name that you enter is for easy identification only, and has no effect on the vLWC. The default vLWC vApp name is the OVA file name.
  6. Select the compute resource (a specific host or a cluster) where you want the vApp installed, and click Next.

    The Review details page opens.

  7. Verify the details listed on this page to make sure everything looks correct with the product, version, vendor, downloaded vApp file size, and the storage capacity of the virtual disk. Once you have verified the details, click Next.

    The Select storage page opens.

  8. Select the datastore you want to use for storing the virtual disk of the vLWC. Select Thick Provision Eager Zeroed as the virtual disk format. Select the VM storage policy and click Next.

    The Select networks page opens.

  9. Select the VMWare network to attach to each network interface using the Destination Network drop-down for each of the source network. You can ignore the IP allocation settings as they are not used by the vLWC. Click Next.

    The Customize template page opens.

  10. Specify the network settings for each vLWC interface over a series of 20 vApp properties. For each interface, select the correct address type. For static address, specify the necessary settings for that interface. You can use the same DNS server for all interfaces.
    Interface Supported IP Address


    IPv4 or IPv6 address


    IPv4 address only


    IPv4 address only

    Once you have configured your network, click Next. The Ready to complete page opens.

  11. Verify the configured settings for the vApp deployment and click Finish to start the deployment of the vLWC.
  12. Wait for VMWare to deploy the vApp. You should see progress bars in the recent tasks section indicating the progress of the vApp deployment. This process can take approximately 30 minutes or more depending on the speed of your cluster, datastores, and your connection to the vSphere.
    • If you encounter the error message “Failed to deploy OVF package. ThrowableProxy.cause The operation is not supported on the object. The operation failed due to The operation is not supported on the object.”, ensure that DRS is enabled for the cluster in which you are deploying the vApp.

    • If you encounter any other error when you click Finish, it is possible that you took too long to complete the steps above and the deployment process timed out. You can reattempt the deployment process if this happens and if you encounter an error for the second time, open a Juniper TAC case for assistance.

  13. To start vLWC, you can right-click the newly created vApp and click Power On from the Actions menu.

    The vLWC is now installed and running in your environment. To confirm, you can view the summary page of the ggc-lnx VM located under the vLWC vApp entry. It should show an Ubuntu Linux (64-bit) VM running with VMWare Tools also running along with the IP addresses assigned to the VM in the IP addresses list.

Once the vLWC vApp is installed, you can add or modify various vLWC settings through the Captive Portal web page (see Configure Network Settings through Captive Portal) or the JSI Shell (see Configure Network Settings through JSI Shell).

Configure Network Settings through Captive Portal

Here's how to view network status and configure network settings using the vLWC Captive Portal web page:

  1. Open a browser on your computer and enter the URL https://cap_interface_address in the address bar, where cap_interface_address can be the configured static IP address, or the IP address assigned by the DHCP server to the management (cap) interface.

    The JSI Data Collector login page appears.

  2. Enter the vLWC serial number in the Serial Number field and click Submit to log in.

    On successful login, the JSI Data Collector page appears.

    The following image displays the JSI Data Collector page when the vLWC is not connected.


    If the default DHCP configuration on the vLWC is successful, the Captive Portal web page shows the vLWC's connection status as connected, and populates the fields in all the configurations sections appropriately.

    Click the Refresh icon under the External Network or Internal Network sections to refresh the current connection states for that section.

    The JSI Data Collector page displays configuration sections for the following:

    • External Network—Lets you configure external network port that connects the vLWC to the Juniper's Cloud. Supports DHCP and static addressing. The External Network configuration is used to perform device provisioning.

    • Internal Networks—Lets you configure the internal network port that connects the vLWC to the Juniper devices on your network. Supports DHCP and static addressing.

    • Active Proxy—Lets you configure the active proxy IP address as well as the port number if your network infrastructure controls access to the Internet though an active proxy. You need not configure this element if you are not using an active proxy.

  3. Click the Edit button under the element that needs to be updated.

    You need to modify the fields in:

    • The Internal Network and External Network sections if their connection states indicate that they are disconnected.

    • The Active Proxy section if you are using an active proxy. This section is collapsed by default if an active proxy is disabled or not configured. To configure, click Enable/disable to expand the Active Proxy section.

      If you choose to use an active proxy, ensure that it forwards all the traffic from the vLWC to the AWS cloud proxy (see Outbound Connectivity Requirements table in Internal and External Network Requirements for the AWS cloud proxy URL and ports). Juniper cloud services blocks all the inbound traffic coming through any path other than the AWS cloud proxy.

    • You must use a different subnet for the IP address assigned to the internal network, external network, and the management (cap) interface. This applies to both DHCP and static configurations.

  4. After modifying the fields, click Update to apply the changes and return to the homepage (the JSI Data Collector page).

    If you want to discard your changes, click Cancel.

    If the vLWC connects to the gateway and DNS successfully, the respective configuration element (internal or external network section) on the JSI Data Collector homepage shows the connection status as Gateway Connected and DNS Connected with green tick marks against them.

    The JSI Data Collector homepage displays the Connection Status as:

    • Juniper Cloud Connected if the external connectivity to the Juniper Cloud is established and the active proxy (if applicable) settings are correctly configured.

    • Cloud Provisioned if the device is connected to Juniper Cloud and has completed the Zero Touch Experience (ZTE) process. After the Cloud connection status becomes Juniper Cloud Connected, it takes about 10 minutes for the provision status to become Cloud Provisioned.

    The following image displays the JSI Data Collector page when the vLWC is connected successfully.

    If the vLWC does not connect to the cloud, click Download Light RSI to download the light RSI file, create a Tech Case in the Juniper Support Portal, and attach the downloaded RSI file to the case.

    In some cases, the Juniper support engineer might ask you to attach the Extensive RSI file to the case. To download it, click the Download Extensive RSI.

Configure Network Settings through JSI Shell

The JSI Shell is an SSH menu system for the vLWC. In addition to viewing the network status, you can use the JSI Shell to view and modify the network settings for the internal network, external network, optional active proxy and the management (cap) interface. See Configure Network Settings through JSI Shell for more information.
