    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: Indicate whether the network interface is physical or virtual. Selecting virtual removes the Connector Type field as it is not applicable.
    • Connector Type: Choose the physical cable connector type for the network interface from options including BNC, SC, LC, ST, Wire Wrap, and RJ45. This selection helps define the physical connection method for cable interfaces.
    • Max physical connection support: Define the maximum number of physical connections supported by this model, which aids in capacity planning.
    • Port bandwidth: Select the bandwidth capacity of the network interface ports to reflect network speed capabilities.
    • Directionality: Specify connection direction types such as Transmit (Tx), Receive (Rx), Tx/Rx Bus, or Broadcast, clarifying data flow roles in the network.
    • Interface Type: Identify the port type on the network interface, including Ethernet, Optical, or Serial, describing connection technology and speed standards.
    • Port position: Document the physical or logical location of the port on the equipment for accurate mapping and troubleshooting.

    Practical Use

    This form enables precise modeling of network interfaces to support network asset management, capacity planning, and configuration tracking within ServiceNow. By capturing detailed physical and logical interface characteristics, users can ensure accurate network documentation and informed decision-making regarding network design and maintenance.

    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 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.

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