    About this task

    The Device to Device Connections uses the OTNetworkUtils script include for the OT device look-up logic. The look-up logic identifies the corresponding Source and Destination CIs based on IP addresses, sites, and managed networks.

    The Device to Device Connections list shows fields from both the OT Device Network Connection [sn_ot_device_network_connection] table and the CI relationships [cmdb_rel_ci] table.

    Procedure

    1. Navigate to All > Industrial Workspace.
    2. Select the List (List icon) icon.
    3. Under the OT Network module, select the Device to Device Connections list.
    4. If needed, edit the following fields.
      Table 1. Device to Device Connections form
      Field Description
      Parent Configuration item (CI) record of the source device.
      Child CI record of the destination device.
      Source IP Address IP address assigned to the source device.
      Source Device CI CI record of the source device.
      Source MAC Address MAC address of the source device.
      Destination IP Address IP address assigned to the destination device.
      Destination Device CI CI record of the destination device.

      To edit the Last Communication Time stamp, perform the following actions.
      1. Navigate to All > Instance Scan > Table Cleanup.
      2. In the sn_ot_device_network_connection record, edit the Age in seconds field as needed. The default is 7,776,000.

    5. Select Save.

    Result

    To view a device-to-device connection for an OT device, you can access the Device to Device Connections related list in the OT device record. For more information about related items and related lists for OT devices, see Edit or view OT devices after import or discovery.
