    Key Features

    • Power (watts): Specify the electrical power consumption of the network asset.
    • Weight (lbs): Enter the physical weight of the network asset.
    • Virtual: Indicate if the network interface is virtual or physical. Selecting virtual hides the Connector Type field.
    • Connector Type: Choose from various physical cable connector types such as BNC, SC, LC, ST, Wire Wrap, or RJ45, each representing common standards for network connections.
    • Max physical connection support: Define the maximum number of physical connections the model supports.
    • Port bandwidth: Select the bandwidth capacity of the network interface ports.
    • Directionality: Specify the data flow direction of the network connection (Transmit, Receive, Transmit/Receive Bus, or Broadcast).
    • Interface Type: Identify the port type — Ethernet, Optical, or Serial — to describe the physical and data transmission characteristics.

    Practical Use for ServiceNow Customers

    By filling out the Information tab accurately, customers can ensure their network interface models reflect real-world specifications, improving asset management and network planning. The fields guide users to capture critical technical details such as power usage, physical connectors, bandwidth, and data directionality, enabling precise configuration and integration within their broader IT infrastructure.

    This detailed data supports effective tracking, compatibility assessment, and operational readiness of network assets managed via ServiceNow.

    The information section in the model form enables you to create, review, and modify the details of a model.

    Table 1. Network Interface Model form - Information tab
    Field Description
    Power (watts) Electrical power of the network asset in watts.
    Weight (lbs) Weight of the network asset in pounds (lbs).
    Virtual
    Option to verify whether the network interface is physical or virtual.
    Note:
    If you select Virtual, then the Connector Type field doesn’t appear.
    Connector Type
    Type of physical cable connector that is used for the connection of the cable to the network interface. Select one of the following options:
    • BNC (Bayonet Neill-Concelman) - Type of miniature radio frequency connector used for coaxial cables.
    • SC (Square Connector)- Square, common type of Fiber optic connector used as push-pull latch, to align the optical fibres for efficient light transmission.
    • LC (Lucent Connector)- Another version of the SC connector designed for high-density applications.
    • ST (Straight Trip)- a type of fiber optic connector commonly used for connecting optical fibers in telecommunications and data communication applications.
    • Wire Wrap -A technique for creating electrical connections on circuit boards.
    • RJ45 - Also known as 8P8C (8 Position 8 Contact) connector, is widely used type of connector for wired Ethernet networks.
    Max physical connection support Maximum number of physical connections that is supported by this model.
    Port bandwidth

    Measured bandwidth for the ports on this network interface. Select the search icon ( Search icon.) and select a bandwidth.
    Directionality
    Type of the connections between the nodes of a network. Select one of the following options:
    • Tx- TX stands for Transmit. It refers to the direction in which data is being sent from a device.
    • Rx- RX signifies the endpoint that receives data. It's the input side for receiving information transmitted from another source, often labeled as TX (Transmit).
    • Tx/Rx
    • Bus- Bus directionality refers to the flow of data on a communication channel.
    • Broadcast- Broadcast directionality refers to the nature of signal transmission and reception in a broadcast system.
    Interface Type
    Type of port on the network interface. Select one of the following options:
    • Ethernet- Physical connection and speed capabilities of a device for connecting to a network. It involves cable type, speed, and standard.
    • Optical- specific design of a connector used in an optical transceiver. There are various types of optical interfaces, each with different shapes and data speed capabilities.
    • Serial- A serial interface transmits data one bit at a time, in contrast to a parallel interface that sends multiple bits simultaneously.
