Running Device Discovery Profiles

You run a device discovery profile to automatically discover, synchronize device inventory and interface details, and manage devices running Junos OS to Junos Space Network Management Platform. Device discovery is a four-step process in which you specify target devices, credentials to connect to each device (that is, reuse existing credentials or specify new ones), and, optionally, the probe method (ICMP Ping, SNMP, both ICMP Ping and SNMP, or none), and the SSH fingerprint for each device. You can run multiple device discovery profiles by using this workflow. If you run multiple device discovery profiles, all devices targets specified in the device discovery profiles are discovered.

Before you start discovering devices, ensure that the following conditions are met:

  • The device is configured with a management IP address that is reachable from the Junos Space server, or the NAT server if you are using a NAT server on your Junos Space setup.

  • A user with the privileges of a Junos Space administrator is created and enabled on the device.

  • The device is configured to respond to ping requests if you intend to use ping as the probe method to discover devices.

  • SNMP is enabled on the device with appropriate read-only v1 or v2c or v3 credentials if you intend to use SNMP as the probe method to discover devices.


To discover and manage a cluster of SRX Series devices, each cluster node must be discovered independently using the management IP address of the respective node.

To run discovery profiles:

  1. On the Junos Space Network Management Platform user interface, select Devices >Device Discovery > Device Discovery Profiles.

    The Discover Discovery Profiles page is displayed.

  2. Select the check boxes corresponding to the discovery profiles you want to run and click the Run Now icon on the toolbar.

    The Discovery Status report appears. This report shows the progress of discovery in real time. Click a bar in the chart to view information about the devices currently managed or discovered, or for which discovery failed.

    A job is created for every device discovery profile you run. From the Job Details page, you can check whether a device was discovered and added to Junos Space Network Management Platform. If a device is discovered, you can view the device on the Device Management page.

    To go to the Job Details page, double-click the ID of the device discovery job on the Job Management page. The Description column on this page specifies whether the device was discovered and added to Junos Space Network Management Platform. If the device was not discovered and added to Junos Space Network Management Platform, the column lists the reason for failure. You can also sort all the columns in ascending or descending order to identify the devices that are discovered and devices that are not discovered.

    To export the device discovery details for all device discovery profiles that are run, from the Job Details page, see Exporting the Device Discovery Details As a CSV File.

Verify the following changes in the Web UI to ensure that the clusters are discovered successfully:

  • In the Manage Devices Inventory page:

    Each peer device displays the other cluster member.

    The devices are displayed as primary and secondary in the cluster.

  • In the Physical Inventory page:

    The chassis information is displayed for each peer device in the cluster.
