Create Logical Interface function
Summarize
Summary of Create Logical Interface function
The Create Logical Interface function in the Telecommunications Network Inventory application enables you to create logical interfaces. These interfaces can serve as termination points for logical connections or as child interfaces of physical or logical interfaces. This function supports multiple child logical interfaces under a single parent interface and allows flexible bandwidth configuration. It also automatically sets the virtual flag for the logical interface. You can incorporate this function as a Workflow Studio action within Telecommunications Network Inventory workflows to automate inventory-related operations.

Key Features
- Parent Interface Relationship: Allows linking the new logical interface to one or multiple parent network interfaces.
- Automatic Naming: If no name is provided, the function generates a model-based name with a unit position number.
- Categorization Fields: Supports optional user-defined codes for Type, Role, and Function to classify network entities.
- Equipment Association: Associates logical interfaces with telecom equipment, defaulting to the parent interface’s equipment if none is specified.
- Bandwidth Configuration: Enables setting the bandwidth for the logical connection.
- Model and Relationship Management: Links the logical interface to a network interface model and manages CI relationships, defaulting to "Contains : Contained By."
- Aggregation Option: Ensures parent interfaces can be restricted to only one child interface if required.
- Workflow Integration: Available as a Workflow Studio action for admins to include in flows and configure accordingly.
Input and Output
Input Fields: Include parent interface(s), logical interface name, type, role, function codes, associated telecom equipment, bandwidth, network interface model, CI relationship type, and an aggregation flag.
Output: Returns a glide record representing the newly created logical interface, enabling further workflow actions or data operations.
Roles and Availability
Only users with the admin role can add this function as an action in workflows and define its configuration details. It is specifically available within the Telecommunications Network Inventory application.
Practical Benefits
This function streamlines the creation and management of logical interfaces, ensuring accurate inventory relationships and enabling flexible configuration. It supports automation and consistency in network inventory workflows, helping ServiceNow customers efficiently manage telecommunications network resources.
The Create Logical Interface function enables you to create logical interfaces in the Telecommunications Network Inventory application.
You can use the Create Logical Interface function to create the logical interfaces that are created either as a termination point for logical connections or as a child of a physical or logical interface. A physical or logical Interface can have multiple child logical interfaces. The bandwidth of the logical Interface isn’t fixed and you can configure it as applicable. Also, this function sets the virtual flag of the logical network interface.
You can use this function as a Workflow Studio action in the Telecommunications Network Inventory workflow.
Roles and availability
Users with the admin role can add an action to a flow and define the configuration details of the flow. This function is available as a Workflow Studio action in the Telecommunications Network Inventory application so that you can perform inventory-related data operations.
Input fields
The following table lists the input fields in the Create Logical Interface function and their descriptions.
| Field Name | Description | Data Type |
|---|---|---|
| Parent Interface | Parent network interface record to create the relationship with a logical interface. Click the add icon ( ) to add an interface. |
Array.String |
| Name | Name of the new logical interface. Note: If you don’t enter the logical interface name, this flow action generates the model name with the number after the maximum number of unit positions. |
String |
| Type | Optional user-defined type code that you use to categorize the types of various network entities or assets. | Reference.TRF Value |
| Role | Optional user-defined role code that you use to categorize the roles or purposes of the various network entities or assets. | Reference.TRF Value |
| Function | Optional user-defined function code that you use to categorize the functions of the various network entities or assets. | Reference.TRF Value |
| Telco Equipment | Equipment that is associated with the logical interface. If you do not enter the name of the equipment, this function selects the associated equipment from the parent interface. | Reference.Telco equipment |
| Port Bandwidth | Bandwidth of this logical connection. | Reference.Bandwidth |
| Product Model | Network interface model that is associated with the logical interface. | Reference.Network Interface Model |
| CI Relationship | Type of CI relationship. By default, the Create Logical Interface flow action sets the CI relationship to Contains : Contained By. The parent interface can support multiple interface record references as an input. If you enter the same parent CI more than once, the system ensures that it associates to a unique set of parent-child relationship. | Reference.CI Relationship |
| Aggregation Interface | Option to ensure that each parent interface must only have one child interface. | True/False |
