Creating a Modeled Instance

You create a modeled instance when you want to quickly add multiple devices to Junos Space Network Management Platform using a common set of connectivity parameters. You add a modeled instance from the Devices workspace.

To create a modeled instance:

  1. On the Junos Space Network Management Platform user interface, select Devices > Model Devices.

    The Model Devices page is displayed.

  2. Click the Create Modeled Instance icon on the toolbar.

    The Create Modeled Instance page is displayed.

  3. From the Device Type drop-down list, select the type of device.
  4. In the Name field, enter a name for the modeled instance.

    The modeled instance name should start and end with letters or numbers and cannot exceed 255 characters. The hyphen (-) and underscore (_) are the only special characters allowed. Leading and trailing spaces are not allowed.

  5. In the Description field, enter a description of the modeled instance.
  6. In the Tag field, enter a tag for the modeled instance and the modeled devices created in this modeled instance.
  7. For Discovery Type, select Add Manually or Upload CSV to provide the details of the devices to be modeled.

    • If you want to provide the details of the devices manually, select the Add Manually option button.

      1. In the Number of Devices field, use the up and down arrows to specify the number of devices to be modeled using the modeled instance.

        The default value is 1.

      2. From the Platform drop-down list, select the platform for the devices.

    • If you want to provide the details of the devices through a CSV file, select the Upload CSV option button.

      1. (Optional) Click the View Sample CSV link to download a sample CSV file.

        You need to retain the format of the CSV file for the devices to be modeled successfully. You need to enter the name of the devices and the platform of the devices in the CSV file.

        Note:

        You need to retain the file format as .csv to successfully upload the details of the devices to Junos Space Network Management Platform.

      2. Click the Select a CSV To Upload link to upload a CSV file.

        The Select CSV File pop-up window is displayed.

      3. Click the Browse button to look for the file on your computer.

      4. Click Upload to upload the CSV file to Junos Space Network Management Platform.

  8. Select the the SNMP Settings check box and then, select either V1/V2C or V3 to specify the version of SNMP to gather information from devices.

    By default, V1/V2C is selected.

    If you select V1/V2C:

    1. Enter the SNMP community string in the Community field.

      By default, the public string is selected.

    If you select V3:

    1. In the User Name field, enter the username.

      The username can contain a maximum of 32 alphanumeric characters including spaces and symbols.

    2. From the Authentication type drop-down list, select the algorithm used for authentication. The options available are MD5, SHA1, or None.
    3. If you selected MD5 or SHA1, enter the password in the Authentication password field.

      If you select None, this field is disabled.

      The following fields are displayed only if you choose an authentication algorithm.

      1. (Optional) From the Privacy Type drop-down list, select the algorithm used for encryption. The options available are AES 128, AES 192, AES 256, DES, or None.

      2. (Optional) If you selected AES 128, AES 192, AES 256, or DES, enter the password in the Privacy password field.

        If you select None, this field is disabled.

  9. (Optional) Push the initial configuration to the devices after the devices are discovered on Junos Space Network Management Platform.

    1. Select the Template Association check box.

    2. From the Device Template drop-down list, select the appropriate device template that contains the configuration that you want to send to the devices.

    Note:

    The Device Template drop-down list does not list Quick templates with variables.

  10. (Optional) Upgrade or downgrade to a common Junos OS version on all devices added using the modeled instance.

    1. Select the Image Upgrade/Downgrade check box.

    2. From the Device Image drop-down list, select the device image that contains the Junos OS version to which you want to upgrade or downgrade the devices.

  11. Activate the devices immediately or later.
    Note:

    Junos Space Platform assigns the Waiting for Deployment state when devices are modeled using the Activate Now option and assigns the Modeled state when devices are modeled without the Activate Now option. You can activate devices using the Activate Now option only by using the device–initiated connection process.

    1. To activate the devices immediately, select the Activate Now check box. This check box is selected by default.

      Enter the following data related to the activation of these devices:

      1. In the Username field, enter the username used to manage to the device.

        The username can contain two through 64 alphanumeric characters. The special characters allowed are hyphen (-) and underscore (_). The username must start with a nonhyphen character.

      2. (Optional) Select the Key Based Authentication check box to use RSA keys for authentication.

        By default, this check box is not selected.

      3. In the Password field, enter the password used to manage the device.

        The maximum length is 20 characters, the minimum length is six characters, and all characters are allowed.

      4. In the Confirm Password field, reenter the password.

      5. (Optional) Select the Serial Number Validation check box to authenticate the device by using the serial number of the device.

        By default, this check box is not selected.

      6. (Optional) Select the Host Name Validation check box to authenticate the device by using the hostname.

        By default, this check box is not selected.

      7. (Optional) From the Connection Profile drop-down list, select a connection profile that specifies the connectivity parameters that you want to use for this modeled instance.

      8. (Optional) If you have not created a connection profile or want to create a new connection profile for this modeled instance, click the Create button next to the Connection Profile drop-down list.

        The Connection Profile pop-up window is displayed. For more information about creating a connection profile, see Creating a Connection Profile.

      9. Select whether you want to automatically push the device template configuration to the device from Junos Space Platform immediately or manually later. The Configuration Update options are Automatic and Manual.

        These options are disabled by default. They are active only if you have chosen the Template Association option earlier.

        • If you choose Automatic, the configuration is deployed to the device when the device is discovered to Junos Space Network Management Platform.

          This option is enabled by default.

        • If you choose Manual, you must load the complete configlet (i.e., you must download the configlet from Device Management ILP), which includes the device template configuration, through a USB device, SFTP server, or FTP server.

      To discover the device to Junos Space Network Management Platform, you must download the configlet (with only the connection parameters or the complete configlet with the connection parameters and the device template configuration), copy the configlet to a USB drive, connect the USB drive to the device, and reboot the device.

      The device connects to Junos Space Network Management Platform and is discovered to the Junos Space Network Management Platform database during the initial discovery process. For more information about activating devices using configlets, see Activating Devices by Using Configlets.

    1. To activate the devices later, clear the Activate Now check box.
    Note:

    If you clear the Activate Now check box and choose to activate the device later, use the Activate Modeled Device workflow from the Device Management page to activate the device.

  12. Click Next

    This page displays the devices that are to be modeled. By default, the devices are given the name you provided for the modeled instance appended with “_#,” where # is a number. The devices are numbered from 1 through the value you specified for the number of devices in this modeled instance.

    If you selected a static connection profile, enter the static IP address and gateway details on a per-device basis.

  13. (Optional) Modify the default hostname, platform, IP address, and gateway details on a per-device basis.
  14. Click Finish.

    The modeled instance is created. You are redirected to the Model Devices page.

    You can view the modeled devices that you created on the Device Management page.

Note:

To view the details of the modeled instance, select the modeled instance and select View Modeled Instance from the Actions menu.
