Today, we introduce some common basic operations of Cisco devices, such as creating VLANs, binding network cables, doing trunks, using three-layer switching, and so on.This is today's topology diagram: Two three-layer switching, two PCs, respectively, add vlan10 and 20, two three layers to do network redundancy, and finally achieve two PC communication, very simple, but the use of an experiment:650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M00/74/4E/wKiom1YYvWzg69qyAACaxI7J60E493.jpg "s

In the use of computers, often due to network configuration errors caused by the inability to surf the internet, affecting work, learning and entertainment, this situation in fact, as long as the Ethernet can be re-enabled. For the Novice computer, it is necessary to master the skills of network configuration. Here is a brief introduction of how to deal with this problem quickly under the WINDOWS8 system. Processing method: 1, right click on the des

Web3 Javascriptðappapi In order for your application to work on the etheric square, you can use the objects provided by the Web3.js library WEB3. At the bottom, it communicates with the local node through RPC calls. The web3.js works with any of the etheric square nodes that expose RPC layers. WEB3 contains ETH objects-Web3.eth (dedicated to the Ethernet block chain interaction) and Shh objects-web3.shh (for whisper interaction). Over time, we'll int

What are the advantages of a small pluggable (SFP) port for a Gigabit Ethernet switch? How do I connect the four SFP ports of a d-link DGS 1248 t smart switch? I think the main advantage of the SFP port is the flexibility to connect to the network. The SFP port is a hot-swappable input/output device that can be plugged into a Gigabit Ethernet port or slot to connect the port to the network. SFP ports can

With the development of the exchange industry in China, we have also promoted the update and upgrade of the exchange technology. Here we have analyzed the problem that Ethernet switches are slowing down for no reason. When the network scale is relatively large, the ethernet switch that handles network data forwarding, content filtering, and management control tasks will be overloaded. In addition, like a pe

SummaryThis paper analyzes the existing Ethernet link layer topology discovery algorithms, proposes improved algorithms, and provides the basic implementation methods of the algorithms. The new algorithm relaxed the conditions in the original algorithm, making the algorithm more widely used and adaptable. The new algorithm can discover devices that cannot be found by the original algorithm in the network. KeywordsLink Layer topology SNMP 1 Intr

Basic protocols running on Ethernet 1. Introduction A network listening tool was compiled some time ago. To analyze captured data packets, you must be familiar with various network protocols. I am suffering from the fact that there are few articles on the Internet that focus on this aspect, and most of the books are not carefully explained. A small number of books devoted to network protocols are too large to meet our requirements. Therefore, we will

In the past, on-site cabling was very simple. The sensor can be either power-supply or passive. The power supply type requires 2, 3, or 4 cables, and the passive type requires only 2 cables. At the same time, the sensors are both analog-type and support 12, 24, 36, 48VDC, or 110, 220VAC voltages. The field controller provides power for each sensor, and each sensor is connected to its related controller. Because the controllers are both analog-type, factory wiring is constantly increasing. When a

Because the single interface between Ethernet devices only provides one network segment, the transmission interface must be set as the receiving interface for OSPF, which prevents OSPF from sending a hello packet to the transmission interface. The two devices can reach each other through the hello packets sent to the receiving interface. To configure the OSPF ticket Ethernet interface, run the following co

Fluke Networks (Fluke Network) has launched an ethernet cable tester "DTX-1800", in addition to the widely used "5e" line, it can also be used to detect "6" and "7" lines with better transmission characteristics. You can check whether the cables used as the measurement object meet the corresponding specifications. The testing frequency is up to 900 MHz. Reduce the testing time of the "6" line to 12 seconds, less than 4300 of the latter, compared to ab

Yesterday accidentally deleted the Xamarin development environment of virtual device network equipment. The name is: vEthernet (internal Ethernet Port Windows Phone Emulator). The code that causes the original to run correctly cannot be edited, prompting for 12 errors, and it is not possible to navigate to a specific error. The relevant method cannot be found in the data. Later, when looking at the error, there was a cryptographic algorithm called FIP
