DDU network settings

Select Network Settings in the Device Discovery and Deployment Utility (DDU) to change the network ranges it scans, its SNMP configuration and its proxy settings. The settings are on three tabs: Network Ranges, SNMP Configuration and Proxy Settings.

Network Ranges tab

The initial scan range is taken from the host addresses entered on the Configure Printer Host Address screen of the HP Secure Print Setup Guide (if any). See Define printer host addresses. The scan range data is stored in the InitialScanRange.txt text file in the DDU’s discovery-deployment-utility\App_Data\Configuration folder.

The Network Ranges tabs allows manual entry of the IP ranges of the devices that you want to scan. IP inclusions and exclusions are supported.

Manual Entry of a Single IP Address

  1. In the Start text field, enter a single IP Address.
  2. Select Add to add the IP address or Exclude to exclude the IP address.

Manual Entry of an IP Address Range

  1. In the Start text field, enter a starting IP Address.
  2. In the End text field, enter an ending IP Address.
  3. Select Add to add the IP address range or Exclude to exclude the IP address range.

Delete IP or IP Address Range

To delete an IP address or an IP address range, select the IP or IP range you want to delete and then select the Remove button. Select Save to save the changes.

SNMP Configuration Tab

Select the SNMP Configuration tab to set the port number, create or delete communities and create, edit or delete SNMPv3 configurations. New communities and configurations are added to the top of their respective lists and can be rearranged using drag and drop.

SNMP Communities

In SNMPv1/v2, security is implemented through the use of communities. HP Insights includes a default v1 SNMP configuration called public, which uses the default SNMP Community string “public”.

To add a new SNMP Community:

  1. In the text field under SNMP Communities, enter the community name that matches the SNMP Community string configured in your devices.
  2. Select Add.
  3. Update SNMP Port Number if required. Default port is 161. The firewall must be configured to allow access through this port.
  4. Select Save.

SNMPv3 Configurations

To add an SNMP v3 Configuration

  1. Under the SNMPv3 Configurations, enter a name to identify the SNMPv3 configuration
  2. Select Add. This opens a SNMPv3 Configuration dialog box.
  3. Enter the SNMP v3 details of the devices.

  • Title – Enter a name to identify the SNMPv3 configuration.
  • Username – Specify the username of the device.
  • Context Name – If configured for a device, enter the context name. This string is case-sensitive.
  • Authentication Protocol – Select the authentication protocol and enter the password associated with the Authentication protocol. Choose from the following options:
    • None
    • MD5
    • SHA1

Note: MD5 is not compatible with FIPS (Federal Information Processing Standards). If you have FIPS enabled and use MD5 as your authentication protocol for a device, you will get the error "Scan ended with error: This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms".

  • Privacy Protocol – Select the privacy protocol and enter the password associated with the privacy protocol. Options to choose from are:
    • None
    • DES
    • AES_128

Note: Both protocols require passwords if the protocol(s) is set to something other than None.

Note: Make sure that all fields exactly match the SNMP v3 settings configured in your network print devices otherwise, the devices may not be discovered.

Note: The Context Name field is required if it is configured for the devices.

  1. Select OK to save changes.
  2. Select Save.

Proxy Settings Tab

To configure the DDU to use proxy server , select the Proxy Settings tab.

No Proxy Use this option if you don't want to use a proxy server. This is the default setting.

Use System Proxy Use this option if you want to use the proxy settings from the local machine's configuration.

Custom Settings Use this option to manually set proxy settings for your site.

To manually set proxy settings, follow these steps.

  1. In the Hostname/Address field, enter a valid proxy server address.
  2. In the Port field, enter the port used by the proxy server.
  3. If required, select Use Authentication and then enter the Username and Password to authenticate on the proxy server.
  4. Select the Test Connection button to check if you can connect to the proxy server.
  5. Select Save. You'll get a prompt to restart the DDU to update the proxy settings.
  6. Restart the DDU by closing and reopening the DDU user interface.

File Options

  • File > Save and File > Cancel behave as the Save and Cancel buttons. Both Save and Cancel operate on any changes made to both the Network Ranges and SNMP Configuration tabs.
  • File > Import: Allows users to import a text or JSON file containing IP and SNMP data.
  • File > Export: Exports IP and SNMP data to a JSON file that the user specifies.

Load

Load > Use Default Network Ranges: When you select Use Default Network Ranges, the DDU will scan the local subnet only based on the IP address and subnet mask of the server on which the DDU is running
