Create Logical Interface function
Summarize
Summary of Create Logical Interface function
The Create Logical Interface function in the Telecommunications Network Inventory application allows you to create logical interfaces. These interfaces serve as termination points for logical connections or as child interfaces under physical or logical interfaces. It supports multiple child logical interfaces per parent and enables configurable bandwidth. The function also sets the virtual flag for the logical network interface and is available as a Workflow Studio action for inventory-related data operations.

Key Features
- Parent Interface Relationship: Links the new logical interface to a parent physical or logical interface.
- Configurable Bandwidth: Bandwidth is not fixed and can be set as needed.
- Virtual Flag Setting: Marks the interface as virtual.
- Flexible Naming: Automatically generates interface names if none are provided.
- Role and Function Categorization: Supports optional user-defined codes for type, role, and function classification.
- Equipment Association: Associates logical interfaces with telecommunications equipment, defaulting to the parent interface’s equipment if not specified.
- Model and Relationship: Allows specifying network interface models and CI relationship types, defaulting to “Contains : Contained By.”
- Aggregation Control: Option to restrict a parent interface to only one child interface.
- Workflow Integration: Can be added as an action in workflows for automated inventory management.
Roles and Availability
Users with the admin role can add and configure this action within flows in Workflow Studio. It is designed for use within the Telecommunications Network Inventory application to facilitate network inventory operations.
Inputs and Outputs
Inputs: Include parent interface reference, optional name, type, role, function codes, associated equipment, bandwidth, network interface model, CI relationship type, and aggregation rules.
Output: Returns a record representing the created logical interface, enabling further processing or integration within workflows.
Practical Benefits for ServiceNow Customers
- Efficiently create and manage logical network interfaces within your telecommunications inventory.
- Customize interface attributes such as bandwidth, roles, and relationships to match organizational standards.
- Integrate logical interface creation seamlessly into automated workflows, improving inventory accuracy and operational efficiency.
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 |
