Create Logical Connection with template subflow
Summarize
Summary of Create Logical Connection with template subflow
The Create Logical Connection with template subflow in the Telecommunications Network Inventory application enables you to create a logical connection record from an inventory template. This process occurs when instantiating inventory using an inventory template, allowing you to efficiently establish logical connections on network interface cards. The subflow also creates and associates the necessary connection elements, including network interfaces, equipment, physical connections, logical connections, and managed functions.

Roles and Availability
Users with the admin role can add this subflow to a flow and configure its details within Workflow Studio. It is designed for inventory-related data operations and is available in the Telecommunications Network Inventory application.
Input Fields
The subflow requires several inputs to accurately create the logical connection and its elements:
- Interface A and Interface Z: Starting and ending network interfaces for the logical connection.
- Change Task: The change task used to instantiate the logical connection.
- Bandwidth A and Bandwidth Z: Bandwidth values at the start and end of the logical connection.
- Connection Type: Defines the type of connection and updates the product model associated with the physical connection.
- Logical Connection Template: The inventory template linked to the logical connection.
- Connection Elements: Array of elements such as network interfaces or equipment added to the logical connection.
- Position, A End Interface Name, Z End Interface Name: Positional and naming details of the logical connection.
Output
The subflow returns key records that include:
- Logical Connection: A GlideRecord reference to the created logical connection.
- CI Relationships with Interface A and Interface Z: References to the configuration item relationships for the starting and ending network interfaces.

The Create Logical Connection with template subflow enables you to create a logical connection record from an inventory template in the Telecommunications Network Inventory application. The logical connection record is created based on the input that you receive when you instantiate an inventory using an inventory template.
You can use the Create Logical Connection with template subflow to create a logical connection from an inventory template on your network interface cards.
This subflow also creates the connection elements and associates them to the logical connection.
If you enter a network interface, equipment, physical connection, logical connection, or managed function as a connection element, the Logical Connection Creation subflow creates the corresponding connection element.
