    Key Features

    • Input Requirements: You must provide at least one of the following: Site, Rack, or Equipment. Optional fields include Availability, Model, Type, Role, and Function, which help categorize network entities.
    • Output Details: The function returns three key outputs:
      • Available Interfaces - sysid list of available network interfaces.
      • Connected Interfaces - sysid list of interfaces connected to other assets.
      • Physical Connections - sysid list of physical connections.
    • Flow Designer Integration: This function can be integrated as an action within the Telecommunications Network Inventory workflows, enhancing data operations.

    Key Outcomes

    By utilizing the Get Interface Summary function, ServiceNow customers can effectively manage network interface data, streamline inventory processes, and reduce errors in network asset tracking. The ability to categorize and retrieve detailed interface information simplifies network management tasks, ensuring better asset oversight.

    The Get Interface Summary function enables you to retrieve all the network interface records that are associated with the input. You can use this function to automatically get the details of the available interface, connected interface, and the physical connection of the equipment in the Telecommunications Network Inventory application when you use Flow Designer.

    Overview

    The Get Interface Summary function enables you to retrieve the network interface records that are associated with the input such as Site, Rack, or Equipment. You must enter the site, equipment, or rack value to return the output.

    If multiple inputs don't match, the action reports an error. For example, let's say that you can see the equipment and site details but because the equipment doesn’t belong to the site, the system reports an error with the conflict information.

    You can use this function as a Flow Designer 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 Flow Designer 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 Get Interface Summary function and their descriptions.

    Table 1. Input fields of Get Interface Summary function
    Field Name Description Data Type Mandatory?
    Site Network site that is associated with the network interface. Reference.Network Site No
    Rack Rack that is associated with the network interface. Reference.Telco equipment holder No
    Equipment Equipment that is associated with the network interface. Reference.Telco equipment No
    Availability
    Status of the network asset. You can select one from the following options:
    • Available
    • Used
    • Reserved
    • Shared
    		 Choice No
    Model Physical connection model that is associated with the network interface. Reference.Physical Connection Model No
    Type Optional user-defined type code that you use to categorize the types of the various network entities or assets. Reference.TRF Value No
    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 No
    Function Optional user-defined function code that you use to categorize the functions of the various network entities or assets. Reference.TRF Value No
    If multiple records are found action Option to return the type of output when multiple records are found. You can select Return only the first record from the list to return the first interface network record. Choice No

    Output

    The following table lists the information about the function output.

    Table 2. Output of function
    Name Description Data Type
    Available Interfaces Returns the sys_id list of the available network interfaces. Array.String
    Connected Interfaces Returns the sys_id list of the network interfaces that are connected to the other network assets. Array.String
    Physical Connections Returns the sys_id list of the physical connections. Array.String

    Example

    If the input is passed as Equipment-1 as shown in the following example where Port-1, Port-2, and Port-3 are connected to Equipment-1, Port-4 and Port-5 are connected to Equipment-2, physical connection-1 between Port-2 and Port-4, and physical connection-2 between Port-3 and Port-5. Then the output is as follows:
    • Available Interface - Port-1
    • Connected Interfaces - Port-2 and Port-3
    • physical Connections - PC-1 and PC-2
    Infographic displaying the connections from the Get Interface Summary action. For the text description, refer to the example description that follows.

    If you select If multiple records are found action as Return only the first record, it returns Port-1, Port-2, and PC-1, respectively.
