Routers play an important role in computer networks and serve as a bridge between computer networks. It not only connects to different networks, but also selects data transmission paths and blocks illegal access. Router configuration is not very easy for beginners. We will introduce general configurations and simple debugging of routers for your reference When configuring routers. This article uses cisco2501 as an example. Cisco2501 has an Ethernet port (AUI), a Console port (

Supplement: The wiring standards of EIA/TIA define the line sequence 568a and 568b of the two twisted pair wires.(1) 568a standard:Green white -- 1, green -- 2, orange white -- 3, blue -- 4, blue white -- 5, orange -- 6, brown white -- 7, brown -- 8(2) 568b standard:Orange white -- 1, orange -- 2, green white -- 3, blue -- 4, blue white -- 5, green -- 6, brown white -- 7, brown -- 8("Orange White" refers to light orange, or cables with orange dots or bars on the white line. The same applies to

through NAT technology, but its control functions need to be improved a lot. These software is very professional and generally not free, so large enterprises use more. 5. ADSL or residential broadband Internet access solutionBy using broadband cats and using dial-up software in the OS, you can use the pppoe protocol to dial up the Internet. To enable multiple machines to access the Internet, you can build a gateway through a router with the pppoe dialing function to guide other machines to acce

Whether it is a LAN, a metropolitan area network or a WAN, it is generally composed of network connection devices and transmission media such as NIC, hub, switch, router, cable, RJ45 connector, etc. Following the growing scale of the network, the number of devices that constitute the network in a rapid expansion of equipment, the variety is also constantly refurbished, may be the day-to-day maintenance of this series of equipment, without regular main

In this article, I will introduce intelligent physical layer management as a whole, and clarify related issues that are relevant to this emerging technology and have not yet been fully elaborated. What is intelligent cabling system Intelligent wiring System is the latest development of structured cabling document and management system. Although network administrators are accustomed to paper-based wiring records and subsequent simple spreadsheets, these methods do not real-time view network con

This is a series of two international standard lines developed by Super Five twisted pair to achieve performance index and unified wiring specification. (Can imagine: in the production of RJ45 Crystal Head, i

USB PLUS This is because the E-sata interface itself does not power, so there is the above figure of the USB plus interface, is the E-sata and USB2.0 combination, to solve the e-sata does not provide power supply defects, this excuse is common on the high-end motherboard.

Routers have a pivotal position in computer network, and are the bridge of computer network. It can not only connect different networks, but also choose the path of data transmission, and can block illegal access. The configuration of routers is not very easy for beginners. Now the general configuration of the router and simple debugging introduced to everyone, for friends in the configuration router reference, this article take Cisco2501 as an example. The Cisco2501 has an Ethernet port (AUI)

Founded in 2013, it has very few employees, a technical-driven, and powerful executive team. I also started to contact StrongLoop in 13 years. At that time, I tried to select nodejs technologies and read many frameworks. LoopBack is the coolest one

If you do not specify Router-id manually , then the router will first see if they have a loopback interface (Loopback), if there is a

During this period, we studied the Sybase MDA monitoring table. During installation, the system always prompts that the loopback service connection is incorrect! Later I found that the loopback service was not provided in the dsedit tool. After creating the loopback interface, you must execute the statement in iSQL. First, set the CIS parameter to 1, indicati
