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.

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

  1. Installing and configuring a Lightweight Collector (LWC) device

  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

Note:

This Quick Start guide assumes that you have ordered the JSI-LWC 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 the Lightweight Collector

The Lightweight Collector (LWC) is a 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.

You can install the LWC on your desktop, in a two-post or four-post rack. The accessory kit that ships in the box has the brackets you need to install the LWC in a two-post rack. In this guide, we show you how to install the LWC in a two-post rack. If you need to install the LWC in a four-post rack, you’ll need to order a four-post rack mount kit.

What's in the Box?

  • The LWC device

  • AC power cord for your geographic location

  • AC power cord retainer clip

  • Two rack mount brackets

  • Eight mounting screws to attach the mounting brackets to the LWC

  • Two SFP modules (2 x CTP-SFP-1GE-T)

  • RJ-45 cable with a DB-9 to RJ-45 serial port adapter

  • Four rubber feet (for desktop installation)

What Else Do I Need?

  • Someone to help you mount the LWC in the rack.
  • Four rack mount screws to secure the mounting brackets to the rack
  • A number 2 Phillips (+) screwdriver

Mount a Lightweight Collector on Two Posts in a Rack

You can mount a Lightweight Collector (LWC) on two posts of a 19-in. rack (either a two-post or a four-post rack).

Here's how to mount the LWC on two posts in a rack:

  1. Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building structure.
  2. Remove the device from the shipping carton.
  3. Read General Safety Guidelines and Warnings.
  4. Attach the ESD grounding strap to your bare wrist and to a site ESD point.
  5. Secure the mounting brackets to the sides of the LWC using eight screws and the screwdriver. You’ll notice there are three locations on the side panel where you can attach the mounting brackets: front, center, and rear. Attach the mounting brackets to the location that best suits where you want the LWC to sit in the rack.
  6. Lift the LWC and position it in the rack. Line up the bottom hole in each mounting bracket with a hole in each rack rail, making sure the LWC is level.
  7. While you’re holding the LWC in place, have a second person insert and tighten the rack mount screws to secure the mounting brackets to the rack rails. Make sure they tighten the screws in the two bottom holes first and then tighten the screws in the two top holes.
  8. Check that the mounting brackets on each side of the rack are level.

Power On

  1. Attach a grounding cable to earth ground and then attach it to the Lightweight Collector's (LWC's) grounding points.
  2. Turn off the power switch on the LWC rear panel.
  3. On the rear panel, insert the L-shaped ends of the power cord retainer clip into the holes in the bracket on the power socket. The power cord retainer clip extends out of the chassis by 3 inches.
  4. Insert the power cord coupler firmly into the power socket.
  5. Push the power cord into the slot in the adjustment nut of the power cord retainer clip. Turn the nut until it is tight against the base of the coupler and the slot in the nut is turned 90° from the top of the device.
  6. If the AC power source outlet has a power switch, turn it off.
  7. Plug in the AC power cord to the AC power source outlet.
  8. Turn on the power switch on the LWC's rear panel.
  9. If the AC power source outlet has a power switch, turn it on.
  10. Verify that the power LED on the LWC front panel is green.

Connect the Lightweight Collector to the Networks

The Lightweight Collector (LWC) uses an internal network port to access the Juniper devices on your network, and an external network port to access Juniper Cloud.

Here's how to connect the LWC to the internal and external network:

  1. Connect the internal network to the 1/10-Gigabit SFP+ port 0 on the LWC. The interface name is xe-0/0/12.
  2. Connect the external network to the 1/10-Gigabit SFP+ port 1 on the LWC. The interface name is xe-0/0/13.

Configure the Lightweight Collector

The LWC is preconfigured to support IPv4 and Dynamic Host Configuration Protocol (DHCP) on both the internal and external network ports. When you power on the LWC after completing the required cabling, a zero touch experience (ZTE) process to provision the device is initiated. Successful completion of the ZTE results in the device establishing IP connectivity on both the ports. It also results in the external port on the device establishing connectivity to Juniper Cloud via. discoverable reachability to the Internet. If the device fails to automatically establish IP connectivity and reachability to the Internet, you must configure the LWC device manually, by using the LWC captive portal.

Note:

You must connect to the captive portal from a local IP address. Connection to the captive portal from the browser will fail if the connection request originates from a non-local network.

Before you configure the Lightweight Collector (LWC), refer to the Internal and External Network Requirements.

Internal and External Network Requirements

The LWC device requires:

  • An internal network port (interface xe-0/0/12) that connects the LWC to the Juniper devices on the network.
  • An external network port (interface xe-0/0/13) that connects the LWC to the Juniper Virtual Private Cloud.

Before connecting the LWC to the internal network, ensure that you have:

  • A DHCP or static IP address.
  • IP connectivity to the Domain Name Server (DNS), all the direct devices on the network, and bastion hosts used (if applicable) to access the devices.
  • Enabled NETCONF in the Junos OS configuration of all target Juniper devices. The LWC uses SSH credentials to connect to the devices on the network and, if used, bastion hosts.

    See also Establish an SSH Connection for a NETCONF Session.

  • Enabled SFTP for the Remote Connectivity Suite over port 22 only for file collection.

    See also Configure Incoming SFTP Connections.

Before connecting the LWC to the external network, ensure that you have the following ready:

  • A DHCP or static IP address.
  • A DNS server in case you have selected a static address. In case of any subsequent change to the DNS, you must inform Juniper about it and get it updated. Otherwise, the LWC might lose connectivity to the external endpoints.

    The LWC supports real static, private static, or DHCP addresses. It prefers Network Address Translation (NAT).

  • Accessibility to the DNS and IP addresses specified in Table 1 through the IP addresses assigned to xe-0/0/13 on the LWC.
Table 1: Outbound Connectivity Requirements
Description DNS Name IP Address Port
Juniper cloud AWSProxy-prod.jssprod.junipercloud.net 52.223.32.79, 35.71.174.221, 35.164.173.102, 52.26.8.178, 54.149.201.209 443

The subnet of the IP address assigned to the internal network port must be different from the subnet of the IP address assigned to the external network port. See Table 2.

Table 2: Static Interface Table Mapping
Network Type LWC Interface LWC Port Identification IP Address Subnet
Network access (internal) xe-0/0/12 0 Internal Static 1 Subnet 1
Juniper cloud access (external) xe-0/0/13 1

External Static 1

Subnet 2

Configure the LWC Manually

Here's how to configure the LWC device manually, by using the LWC captive portal:

  1. Disconnect your computer from the Internet.
  2. Connect the computer to the port ge-0/0/0 on the LWC (labeled as 1 in the image below) using an Ethernet cable (RJ-45). The LWC assigns an IP address to the Ethernet interface of your computer through DHCP.
  3. Open a browser on your computer and enter the following URL to the address bar: https://cportal.lwc.jssdev.junipercloud.net/.

    The JSI Data Collector login page appears.

    Note:

    On Captive Portal versions earlier than 1.0.43, if you are unable to configure an IP address via. DHCP, you must manually assign an IP address to the connecting device and accept an unsecured connection. For more information, see https://supportportal.juniper.net/KB70138.
  4. Enter the LWC serial number in the Serial Number field and then 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 LWC is not connected (version 1.0.43 and later releases).

    The following image displays the JSI Data Collector page when the LWC is not connected (releases earlier than version 1.0.43).

    Note:

    If the default DHCP configuration on the LWC is successful, the captive portal shows the LWC'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 LWC 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 LWC 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.

  5. 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.

      Note:

      If you choose to use an active proxy, ensure that it forwards all the traffic from the LWC to the AWS cloud proxy (see Outbound Connectivity Requirements table in Configure the Network Ports and Active Proxy 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.
      Note:

      If you choose to use an active proxy, ensure that the LWC's external interface IP configuration can reach the active proxy's URL or IP address.
      Note:

      In version 1.0.43 and later releases, the Active Proxy 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.
    Note:

    • The subnet of the IP address assigned to the internal network port must be different from the subnet of the IP address assigned to the external network port. This applies to both DHCP and static configurations.
  6. 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 LWC 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 LWC is connected successfully (version 1.0.43 and later releases).

    The following image displays the JSI Data Collector page when the LWC is connected successfully (releases earlier than version 1.0.43).

    If the LWC 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.

    The Juniper support engineer might ask you to reboot the LWC for troubleshooting. To reboot the LWC, click REBOOT.

    If you want to shut down the LWC, click SHUTDOWN.
