The configuration of network management switch has always been fascinated by many people, not only for the general users, but also for many professional users, but also as an important and basic indicator of the level of network management. this is mainly in two reasons, one is the vast majority of enterprises configured switches are desktop non-network management switch, do not need any configuration, is purely "fool" type, and the same as the hub,
The ethernet switch technology has become more mature and stable. Because the Ethernet switches in the industry share many similarities with the switches we usually use, the design of the Industrial Ethernet switch also uses the principle of the commercial switch. With the rapid development of Ethernet technology and its wide application in the commercial field, more and more industrial control devices grad
A comprehensive explanation of the flexible configuration of gigabit core switches, many problems will be encountered during access to gigabit core switches, and how to solve these problems has become a necessary task for everyone, the following describes how to coordinate Ge core switches and other problems. After the success of the gigabit core switch GSM7324,
Many users do not know how to buy VLAN switches. The most fundamental factor is to choose a cost-effective product that suits their needs. As enterprises pay more attention to information security, more and more enterprises begin to consider deploying Virtual LAN in the enterprise, in order to put confidential departments of some enterprises, for example, the R D department's network is isolated through the Virtual LAN to ensure data security. I. How
, that is, QoS ). Currently, common QoS technologies include IntServRSVP and DiffServ. The former uses the Resource Reservation method, that is, for each different application, the "End-to-End" dedicated channel is reserved on the network, to ensure that key applications enjoy dedicated bandwidth resources. Resource Reservation is a virtual leased line solution that ensures the transmission quality of key applications, but cannot achieve bandwidth sharing, which can easily lead to a waste of lin
Ethernet includes three network interfaces: RJ-45, BNC and AUI, the transmission media used are: twisted pair wire, thin coaxial cable and coarse coaxial cable, after reading this article you certainly have a lot of GAINS, I hope this article will teach you more things. More work needs to be done for manufacturers to use Ethernet in large-scale data centers. According to users attending the Ethernet Technology Summit in San Jose this week, Ethernet can be greener and "more structured ". This ind
Enterprise switches are worth learning a lot. Here we mainly introduce common troubleshooting methods for enterprise switches. Enterprise switches have various faults, and different faults have different forms. In case of failure analysis, you must use various phenomena to flexibly use troubleshooting methods (such as exclusion, comparison, and replacement) to lo
GE switches are still commonly used. So I studied the performance test of GE switches and shared it with you here. I hope it will be useful to you. 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 GE switches
Layer-3 Switch for Cisco switches Although single-arm routing solves the communication problem between different VLANs, it also has its fatal defects: -The single arm itself is the Backbone link of the network, which is easy to form a network bottleneck. -The sub-interface relies on physical interfaces, and the application is not flexible -You need to view the route table for each vlan forwarding, wasting device resources. The problem above is caused
this series of switches include: S2026C/Z-SI, S3026C/G/S-SI and E026-SI. Huawei switch: S3050C series port image configuration process Mirror ing-port is used to define the mirror port, and monitor-port is used to define the monitoring port. [Switch configuration] 1. Configure port E0/2 as the monitoring port [SwitchA] monitor-portEthernet0/2 2. Configure port E0/1 as the mirror Port [SwitchA] mirroring-portEthernet0/1 both [Additional de
Internet of Lights and switchesTime limit:1 Sec Memory limit:128 MBSubmit:3 Solved:3[Submit] [Status] [Web Board]DescriptionYou is a fan of "Internet of Things" (IoT, IoT ), so you build a nice Internet of Lights and switches in your huge Mansion. Formally, there is n lights and m switches, each switch controls one or more lights, i.e. pressing that s Witch flips the status of those lights (On->off, Off->o
Many enterprises are currently using core switches. Here we mainly explain the main factors and problems that affect the development of enterprise-level Core switches. Currently, most enterprises in China generally access their networks through the backbone networks of China Telecom. They can only complete some basic information exchange functions, it cannot meet enterprises' complex network application req
Wireless switches are worth learning a lot. Here we mainly introduce how to effectively reduce the burden that wireless switches bring to enterprises. The advantages of wireless switches are mainly reflected in three aspects, higher security, lower TCO, and more efficient management. With the increasing popularity of wireless networks, more and more institutions
, it must be immune and provide powerful blocking measures to protect network users, all defense measures should be implemented based on hardware. However, all security measures are based on known attack methods and security vulnerabilities. If we cannot monitor the entire network, security will not be a complete feature ., Taking into account the high-speed forwarding of 10-ge switches and routes, the previous method of collecting traffic by CPU will
GE switches are still commonly used. So I have studied the parameters and functions of GE switches. I will share them with you here, hoping they will be useful to you. When evaluating and selecting equipment, we should pay attention to the following aspects: product type; gigabit port density and type supported by the product; product performance; after-sales service; management features and security and re
LAN switches are still commonly used. So I studied the problems encountered in the development of LAN switches. I would like to share them with you here, hoping to help you. Traditional LAN switches are preparing for major improvement. The focus of improvement is obviously on intelligence rather than aesthetics. The next-generation switch not only provides embedd
Fiber switches are quite common, So I studied the most suitable fiber switches for small and medium enterprises. With the increasing number of network data and the frequency of network applications, many enterprises have begun to realize that they need to build their own storage system networks to meet the increasing data storage performance requirements. Currently, the most popular data storage Network is
With the development of the exchange industry in China, the wide application of gigabit smart switches has been greatly promoted. At present, Gigabit smart switches have improved many shortcomings and provide users with a good user experience. Tcls4rjsfb of TCL Network Equipment Co., Ltd. is a gigabit smart switch with Simple Network Management and belongs to working group-level network equipment. Based on
The second wave of 802.11ac may force the upgrade of Enterprise Ethernet Switches The second wave of high bandwidth of 802.11ac may force enterprises to upgrade to a faster Ethernet switch in 2015. With the adoption of the second wave of 802.11ac wireless technology in 2015, many enterprises may need to upgrade Ethernet switches to support wireless network connections with higher bandwidth. In 2014, many e
