Create an IP network subnet record

Define an IP network subnet so that you can categorize and manage all the child IP network subnets in your network by using the Telecommunications Network Inventory application. You can also review, create, or delete an IP subnetwork.

Before you begin

• Get access to the IP subnetwork by ensuring that you’ve installed all advanced plugins.
• Role required: sn_ni_core.inventory_admin, sn_ni_core.inventory_agent

About this task

When you create a IP network subnet record, it creates a corresponding configuration item (CI) record in the IP Network Subnet [cmdb_ci_ip_network_subnet] table.

Procedure

1. Navigate to Workspaces > Network Inventory Workspace.
2. Select the list icon (), and then go to Inventory > IP Network Subnets.
3. Select New
4. On the Details tab, in the IP Network Subnet section, fill in the fields.

   Table 1. IP Network Subnet form

   Field	Description
   Name	User-friendly name for this IP network subnet.

   To learn about the other fields, see Inventory number allocation fields.

5. Create the Telecommunications Network Inventory attributes for this IP network subnet form by selecting Set Inventory Attributes.
   When you select the Set Inventory Attributes button, it creates the TNI CI Attributes record in the CI table and in the Telecommunications Network Inventory CI Attributes tables and makes a relationship with the CI record.

   Note:

   • If you select Save without selecting Set Inventory Attributes, it creates a CI record but not a Telecommunications Network Inventory CI record. In the network inventory workspace, the Set Inventory Attributes is visible only for the Telecommunications Network Inventory roles.
   • In the TNI CI attributes form, by default, the name is fetched from the Name field and the Inventory Category is set as IP Address.
6. Add packs to this service by selecting Add Packs.

   To learn more about the packs, see Attribute packs.

7. Add the attachments, such as the graphics or documents, by selecting the attachment icon () in the right panel.
8. Select Save.
9. View the hierarchy or flow chart of the created IP pool by selecting the Dependency View button.
10. View the associated network inventories by selecting the brick icon ().

    The Infrastructure Relationships section shows all the associated network inventories that are grouped by the individual network instances.

What to do next

You can review and update the fields, create a related tab record, or delete a record. To learn more, see Update or delete a record of an inventory number allocation.
