    Key Features

    • Power (watts): Specify the electrical power consumption of the network asset.
    • Weight (lbs): Enter the physical weight of the network asset in pounds.
    • Virtual: Indicates whether the network interface is physical or virtual. Selecting virtual hides the Connector Type field.
    • Connector Type: Choose the physical cable connector type used, such as BNC, SC, LC, ST, Wire Wrap, or RJ45. This selection defines the physical interface and cabling standards.
    • Max physical connection support: Define the maximum number of physical connections supported by the model.
    • Port bandwidth: Select the bandwidth for the network interface ports from predefined options.
    • Directionality: Specify connection direction using options like Tx (Transmit), Rx (Receive), Tx/Rx Bus (bi-directional), or Broadcast.
    • Interface Type: Select the type of port on the network interface, including Ethernet, Optical, or Serial, each with distinct characteristics and use cases.
    • Port position: Define the physical or logical position of the port on the equipment.

    Practical Use

    By accurately completing the Information tab fields, customers can ensure that network interface models reflect the correct physical and functional attributes. This precision supports better network design, troubleshooting, inventory management, and integration with other ServiceNow modules.

    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 fibers 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.

    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.
    Port position Position of a physical or logical port on an equipment.
