# Create Logical Connection function

# Create Logical Connection function {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
The Create Logical Connection function enables you to create a logical connection record
in the Telecommunications Network Inventory application based on the input (interfaces) that
you receive when you instantiate an inventory.
You can use the Create Logical Connection function to create a logical connection on your network interface cards.

When you enter the Interface A, this function automatically retrieves the data for Site A, Equipment A, and Port A. Similarly, after passing input Interface Z, the function retrieves the data for the associated Site Z, Equipment
Z, and Port Z. This function also retrieves the data for Bandwidth AtoZ and Bandwidth ZtoA from the Bandwidth field.

This function also creates the connection elements and associates them to the logical connection.

If you configure a network interface, equipment, physical connection, logical connection, or managed function as a connection element, the Logical Connection Creation function creates the corresponding connection element and
associates it to a logical connection.

You can use this function as a Workflow Studio action in the Telecommunications Network Inventory workflow.

## Roles and availability {#create-logical-connection-action__section_kfd_fdk_x5b}

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 {#create-logical-connection-action__section_xbc_vyp_x5b}

The following table lists the input fields in the Create Logical Connection function and their descriptions.
{#create-logical-connection-action__table_w3g_2fm_1vb__entry__3}

| Field Name | Description | Data Type |
|-|-|-|
| Interface A | Starting network interface where this logical connection is configured. | Reference.Network Interface |
| Interface Z | Ending network interface where this logical connection is configured. | Reference.Network Interface |
| Bandwidth | Bandwidth of the logical connection. | Reference.Bandwidth |
| Connection Type | Type of connection. This field information updates the product model that is associated with the physical connection. | Reference.Logical Connection Model |
| Connection elements | Connection elements that are added for the logical connections. Click the add icon (![Add icon.]()) to add a connection element. | Array.String |
