VLAN in the initial design of the network can bring great benefits to the future expansion of the network. In ordinary small enterprises, the use of routers to divide VLAN is a cost-saving method, but in large and medium-sized enterprises, the use of routers to divide the VLAN will seriously affect the performance of the enterprise network, and the communication between VLANs must be routed to achieve, therefore, The three-layer switch with routing

network security protection not perfect, the network security can not rely on single device, single technology to realize has become the consensus of the industry. In the "soft and hard combination", "internal and external" and other industry recently widely promoted by the security strategy, the switch as the backbone of the network equipment, naturally also shoulder the task of building network security defense. 　　 The

In recent years, with the hundred trillion, gigabit, even the gradual popularization of gigabit LAN, broadband LAN, and even wide range of bandwidth network applications, driving the development of the exchange technology. Enterprise applications, the rapid development of the Internet, E-commerce, e-government, electronic trade, electronic futures, such as the use of network transactions, in the acceleration of logistics, capital flow turnover, but also accelerated the rapid increase in informat

The exchange network technology is still quite common, so I have studied the types of the exchange network technology and the precautions in the application. Here I will share with you, I hope it will be useful to you. In 1993, LAN switching equipment emerged. In 1994, the exchange network technology boom began in China. In fact, the exchange network technology is a simplified, low-cost, high-performance and high-port intensive exchange product, reflecting the complex exchange network technology

We know that the core part of a network is the key to the entire networking, and many enterprises have chosen layer-3 switches as the core of the entire network, A layer-3 switch is a common vswitch with a route function added. Do not underestimate the added routing function of a layer-3 Switch. When a layer-3 switch is added with the routing function, VLAN divis

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 configuration mode of the switch can be broadly divided into two categories: one is the configuration mode represented by the Cisco switch, and the other is the configuration mode represented by Huawei and the H3C switch. In fact, the two configuration modes are not fundamentally different, but the configuration of the command name and configuration of the wa
