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

Introduction There are many technologies to achieve broadband access. FTTx + LAN is one of the most popular technologies at present.The so-called FTTx + LAN technology is to use a computer LAN to access end users on the basis of optical fiber to the

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

How does one filter user communication to ensure secure and effective data forwarding? How can we block illegal users and protect network security applications? How can we conduct security network management to promptly discover illegal users,

Network technology is developing rapidly, and Ethernet occupies a dominant position. In order to adapt to the challenges brought by the deepening of network applications, the scale and speed of the network are rapidly developing. The speed of the

1. How is the stacking of Catalyst 35500XL/2950XL implemented? A. dedicated stacked cables, 1 m long or 50 cm long (CAB-GS-1M or CAB-GS- 50CM) and dedicated Gigabit stacked card GigaStack GBIC (WS-X3550-XL) (the card already contains CAB-GS- 50CM

Introduction With the rapid development of information technology, especially the continuous improvement of computer and network technologies, people have higher and higher requirements for network transmission, in the competition, Ethernet stands

With the gradual development of network applications, telecom-grade switches, especially layer-3 switches, have become the focus of competition in today's market. However, how do users discover products that meet the characteristics of their own

As the core connection device of an enterprise network, a vswitch has the primary performance standard to ensure the speed of the enterprise network. To help readers better understand the overall performance of the vswitch, we use the industry's

Like the bridge adapter, the switch simply decides to forward information based on the MAC address in each package. This type of forwarding decision generally does not consider the deeper information hidden in the package. The difference with the

A vswitch is not designed as a security device, but is still designed to improve network performance. If you want to add a vswitch to the security mechanism, make sure that you configure the vswitch correctly, second, the switch manufacturer must

Many switches can prevent ARP attacks on the Gateway at the core layer, but they cannot effectively prevent attacks between VLANs and prevent attacks between VLANs. I think it is better to use the VACL in a VLAN to prevent attacks, security

With the rapid development of e-commerce and distance learning, more and more functional requirements for Intranet networks are required. The faster the speed, the higher the security performance. The two main causes of network bottlenecks are

Many people do not know much about the configurations of broadband wireless routers in the Community. Let's give a comprehensive explanation of this problem. In addition to broadband access through virtual dialing such as ADSL, most families

You may not know the installation and setting process of the router. In fact, the installation and setting are the same. It's just a different name. You must pay attention to some details during the installation and setup process. Otherwise, even if

My friend lost his manual and forgot the initial value of the Alpha router address. I tried a lot of common Alpha router addresses, but they were useless. I finally solved the problem with the help of a netizen. I 'd like to share with you

The use of the router IP auto-changer can help us automatically allocate IP addresses. In the following article, we will explain the configuration of the router IP auto-changer in five steps. This article also comes with a lot of vroip IP auto

The following is a code-only explanation of the dual-WAN port vro configuration document, which is helpful to professionals. In this way, China Telecom egress and China Netcom egress can be automatically allocated. You can try it! Code-only

It is very important to know some knowledge about vro parameter settings. Here we mainly explain the common solutions to the connection failure caused by vro parameter settings, in many cases, when we use multiple computers and broadband (Wireless)

With the development of China's routing industry, enterprise-level routers are also more widely used. Here we mainly introduce a highly cost-effective enterprise-level router, and Xin Xiang is a well-known brand of routing, enterprise Users are
