With the increasing popularity of wireless networks, more and more institutions and enterprises are beginning to implement wireless LAN. Up to now, wireless LAN is generally composed of clients connected to the access point, and the Access Point must provide security, management, and other intelligence required to control the wireless part of the network. The problem is that managing multiple access points is an insurmountable situation for networks that may involve hundreds or thousands of acce
The use of wireless switches brings more convenience to enterprises. Its performance makes enterprise network management easier and more systematic. Let me study the three advantages of wireless switches. I hope this article will help you understand the features of the wireless switch. The problem is that managing multiple access points is an insurmountable situation for networks that may involve hundreds or thousands of access points. In this case, a
What kind of open computing switch can you buy? Whether you love it or hate it, the Open Computing Project (OCP) has made waves in the hardware world of the data center. When Facebook decided to develop and produce its own high-performance data center switch, it reminded network giants Cisco and Hewlett-Packard to let them know that the present is a changing era. Two years ago, Facebook announced the devel
Quickly set the loading process of the quick switch on the panel, including the process of loading and clicking events such as icons, and the main process of creating a shortcut switch (to add a lock screen switch for example). The Android version discussed in this article is 5.1. The loading process of the shortcut
Switch Summary:The similarities between the switch and the bridge are as follows:1. Bridges and switches are linked to LAN segments.2. Bridges and switches use the MAC Address table to identify the network segment to which the data frame is destined.3. Bridges and switches help reduce network traffic.Switch-to-bridge is a great advantage to eliminate network congestion:1. Dedicated inter-device communicatio
The core switch is still quite common, so I have studied the displaycpu command details in the switch. Here I will share it with you and hope it will be useful to you. In the LAN operating environment, the working status of core switch equipment is extremely important. It directly affects the efficient and stable operation of LAN networks. When a fault occurs in

What exactly is trunk? What are the advantages of using the trunk function to us in the application? And how to switch trunk configuration in a specific switch product, let's take a look at these areas of knowledge. In the performance parameters of the two-tier switch. often mentions an important metric: TRUNK, many of the two-tier
The last article on how to use LoadRunner monitor Linux performance indicators, but the CPU on a few indicators are not clear, the following detailed said. CPU Utilization good understanding, that is, CPU utilization, more than 75% is higher (also has the argument is 80% or higher). In addition to this indicator, but also in combination with the load average and context Switch rate, it is possible that the high CPU is due to the latter two high indic
the cache entries of the old a address space will affect the translation of the address space of the B process, so when the process switches, the TLB operation is required to clear the effects of the old process. We have one by one discussions below.2, absolutely no problem, but poor performance of the programWhen the system has a process switch, from process A to process B, which causes the address space to swit
Beginner: I learned about the basic features of a layer-3 Switch. Some time ago, my colleagues asked me questions about the basic features of the layer-3 Switch. At that time, I did not give a positive answer, I was also the first to have a problem with the basic features of a layer-3 Switch. In the following days, I checked the relevant information and was satis

Lan exchange technology can also be called layer-2 Switch Exchange Technology, the content mainly includes the working principle of Layer 2 switching, network loops, and how to use the Spanning-Tree Protocol to solve Network loops, VLANs, and VTP technologies, this article mainly introduces the working principle of L2 switches and the dangers of network loops. Other content will be introduced later. We all know that the traditional shared Ethernet use

With the further construction of China's information network, the further improvement of network quality, high-speed, high-performance Ethernet switch will become the mainstream of network product development. switch is an essential equipment for the network of large and medium sized enterprises, it plays a very important role in network construction, it can increase network capacity and improve network s
This digest is from http://www.pconline.com.cn/pcjob/ittest/network/0312/258919.htmlOther literature http://www.jztop.com/s/jiaohjjs/ Comparison of three-layer switch and router In order to meet the challenge of deepening the network application, the network has been developing rapidly in both scale and speed, the speed of LAN has been improved from the initial 10mbit/s to the 100mbit/s, and the Gigabit Ethernet technology has been widely used at pres
Generally, the failure of a vswitch is caused by the time used. As the Working Hours extend and network applications change, the chance of a problem increases greatly. A switch is an important device in a network. If a problem occurs, it will affect the entire network system. Therefore, we have analyzed the troubleshooting methods for common switch faults. Computers in the LAN are often connected to
After the switch system is restarted successfully and the VRP platform software has been updated, it is necessary to carefully and carefully maintain the updated software, next, let's give some comments and opinions on the switch system. As a core network terminal in a LAN, maintaining the switch system becomes very important. In order to make the LAN work more s
