The digitalization and network of embedded devices have become an inevitable trend. Currently, mainstream emb

One: The NPF driver isn ' t running This error is caused by not opening the NPF service. NPF, the network packet filter (Netgroup Packet FILTER,NPF), is the core part of WinPcap, which is the component of WinPcap to complete the difficult work. It handles packets transmitted over the network and provides a capture, send (injection) and analytical performance (analysis capabilities) to the user level. It not only provides basic features (such as grasping packages), but also has more advanced f

New Cisco Routers and switches come with a dedicated Ethernet port which unique purpose are to provide management access to the device via SSH or Telnet.This interface was isolated in its own VRF called "MGMT-VRF". Placing the management Ethernet interface in its own VRF have the following effects on the management Ethernet interface: Many features must b

I Current Status and Development of Industrial Ethernet Technology The so-called industrial Ethernet is technically compatible with commercial Ethernet (that is, the 802.3 standard), but in product design, it can meet the needs of industrial sites in terms of material selection, product strength, applicability and real-time performance.With the development and po

1. Work Summary Recently, the IEEE is working on a new project the project is to develop a standard for the operation of Gigabit Ethernet (10GbE) transmission based on the current copper structured cabling system, which is collaborating with leading experts from integrated wiring, electrical, test equipment and system design, Panduit belong to one of the leading ranks, we have foreseen that with the future increase in transmission rate, cable and conn
