There is a button, and we click it to slide it, "On" will be displayed, and "off" will be displayed. This is the switch button. For example, many functions of the

In front of you to explain a multi-choice ElseIf statement, although this statement can make a variety of judgments, but when used, need to write a lot of if statements, to our program readability inconvenience, in order to avoid the IF statement too much and improve the readability of our program, you can use the switch multiple judgment statement, In this chapter we will introduce you to the "switch state

In a switched network, how do you decide where to start looking for problems? It is very difficult to delve into the "perspective" of a switched network. First of all, in the 2-tier exchange or bridge forwarding, but to the 3-tier exchange has more advanced features and forwarding rules, such as VLANs. To the 4-tier exchange, it is more complex, there are more advanced forwarding and load balancing technology, fault diagnosis and resolution of troubleshooting needs more knowledge of

How to quickly resolve switch faults and effectively improve network efficiency. Please refer to this article for details: 1. Solve the trouble of resetting VLAN When managing and maintaining a LAN, if the cascade port connecting to a common switch changes, the VLAN previously configured in the switch system may not work normally. In this case, do we have to re-

In recent years, with the popularization of Mbit/s, Gbit/s, and even Mbit/s, the wide application of Broadband LAN and even Bandwidth WAN has driven the continuous development of switch technology. In enterprise applications, the rapid development of Internet, the adoption of e-commerce, e-government, e-trade, e-futures and other online trading methods, while accelerating logistics and capital flow turnover, it also accelerates the rapid increase of i

The superior performance and price of vswitches are greatly reduced, promoting the rapid popularization of vswitches. Network administrators often encounter a variety of switch faults at work. How can they quickly and accurately find and eliminate faults? This article briefly introduces common fault types and troubleshooting steps. As vswitches are widely used in the company's network, from the low end to the middle end, from the middle end to the hig

The concept of management is very important to all walks of life. If an enterprise cannot effectively manage it, the cohesion of the Enterprise will be very weak and the development of the Enterprise will be severely hindered; if an army is not managed, it will become a sandbox with no fighting power. If a network cannot be effectively managed, the use of such network resources will become messy. Therefore, it is very important to manage the network. For the management of the grass-roots layer i

What are the differences between hub, switch, router, and modem ??? What types of networks are available (local area, wide area, and enterprise )?How should the above components be connected for each network type? ========================================================== ============== Hub ------- a hub is also called a hub. It works on the physical layer (bottom layer) and does not have a matching software system. It is a pure hardware device. A hub

Absrtact: Spanning tree algorithms and protocols are the basis for automatically generating network topologies. This paper expounds the content of spanning tree algorithm and protocol, and gives the realization process in Ethernet switch. It is proved by practice that the square tip has a good effect on the analytic optimal topological structure of the network. The Ethernet switch must have routing capabil

I believe many people know that layer-4 switches are commonly called Application switches in the industry. Here we will mainly introduce layer-4 switch technologies and functions. With the popularization of broadband and the deepening of various network applications, our local network is undertaking heavy business traffic. The amount of transmitted audio, video, data, and other information in the network system is full of bandwidth. We have to provide

With the advent of the Internet era, security issues have become an urgent issue. The existence of viruses, hackers, and various vulnerabilities makes security tasks extremely difficult in the Internet era. Vswitches play an important role in the enterprise network, usually the core of the entire network. In the network era where hackers are intruding into the cloud and the virus is raging, the core switch also takes responsibility for network securit
