  • What does LPU mean on the core switch

    What does LPU mean on the core switch

    The Line Processing Unit (LPU), also referred to as the interface board and labeled CR5DLPUF517E, is responsible for managing data traffic within the network device. The MPU interprets the device configuration and then transmits it to the LPU. It's mostly used in Networking and Telecommunications. Network devices are divided into three core planes: the data processing plane, the control and routing plane, and the system management plane. In LPU connection mode, management links and forwarding links are integrated.
