Merging devices

Expand all | Collapse all

If one device is represented by multiple devices in the table for some reason, these devices can be merged into one device. Devices can be merged automatically when the device activity detection method is enabled in learning mode. You can also manually merge devices.

Devices are automatically merged if the application identifies a connection between the MAC address of one device and the IP address of a different device, or identifies a connection between devices according to the results of an active poll or data received from EPP applications. If conflicts arise between defined values in device information, the merged device will retain the values that were defined for the following devices:

• Devices with IP addresses, if a connection is detected between the MAC address of one device and the IP address of a different device.

  Prior to enabling learning mode (and while working in this mode), it is not recommended to change information about devices for which only a MAC address is defined if they could be automatically merged with devices that have defined IP addresses.

• Devices with IP addresses and Kaspersky Endpoint Agent installed, if a connection is detected between devices according to data from EPP applications.
• Devices with the most IP addresses.
• Devices with the most addresses, if the devices do not have an IP address.

When devices are merged, some information from the merged devices might not be saved in the new device (for example, the contents of dynamic fields and topology parameters). In addition, to merge devices, the total number of network interfaces in the new device must not be more than 512.

Only a user with the Administrator role can manually merge devices.

You can merge devices in the following ways:

• Merging devices when working with the devices table
  1. Connect to the Kaspersky Industrial CyberSecurity for Networks Server through the web interface using the Administrator account.
  2. Select the Assets section.
  3. On the Devices tab, select the devices that you want to merge.
  4. Click the Merge devices button.

     The details area with the tabs for configuring the new device settings appears in the right part of the window.

  5. Check the settings of the new device and edit them if necessary:
     • On the Settings tab in the details area, all fields containing conflicting values in the selected devices are marked by messages regarding the conflicting values. The conflicting values are merged into one value in text fields. If necessary, enable or disable automatic updates for the relevant information about the device.
     • On the Address information tab, in the details area, the MAC and IP addresses of the selected devices are distributed by individual network interfaces. If necessary, change the values of addresses, address spaces, and the names of network interfaces, and enable or disable automatic updates for the relevant information about the device.
     • On the Custom fields tab in the details area, the list contains all custom fields of the selected devices.
  6. Click the Merge button.

     A window with a confirmation prompt opens.

  7. In the prompt window, click OK.

  The devices table will show the new device with the Authorized status.

• Merging devices when working with the networking interactions map and the topology map

  When working with the network interactions map, and the topology map, you can merge multiple nodes on the maps into one new device for the devices table.

  You can select the relevant nodes individually or as part of collapsed groups that include the relevant devices. When a collapsed group is selected, all devices in the child groups of any nesting level are also included in the device selection.

  WAN nodes cannot be merged.

  To merge devices represented by nodes on the maps:

  1. Connect to the Kaspersky Industrial CyberSecurity for Networks Server through the web interface using the Administrator account.
  2. Select the Network map section.
  3. On the Network interactions map or Topology map tab, select several objects which represent nodes and/or collapsed groups.

     To select multiple nodes and/or groups, do one of the following:

     • Hold down the SHIFT key and use your mouse to select a rectangular area containing the relevant objects.
     • Hold down the CTRL key and use your mouse to select the relevant objects.
  4. Click the Merge devices button.

     The details area with the tabs for configuring the new device settings appears in the right part of the window.

  5. Check the settings of the new device and edit them if necessary:
     • On the Settings tab in the details area, all fields containing conflicting values in the selected devices are marked by messages regarding the conflicting values. The conflicting values are merged into one value in text fields. If necessary, enable or disable automatic updates for the relevant information about the device.
     • On the Address information tab, in the details area, the MAC and IP addresses of the selected devices are distributed by individual network interfaces. If necessary, change the values of addresses, address spaces, and the names of network interfaces, and enable or disable automatic updates for the relevant information about the device.
     • On the Custom fields tab in the details area, the list contains all custom fields of the selected devices.
  6. Click the Merge button.

     A window with a confirmation prompt opens.

  7. In the prompt window, click OK.

  The devices table will show the new device with the Authorized status. The network map will show one merged node instead of the previously selected multiple nodes.
