With the increasing popularity of Mbit/s, Gbit/s, and even Mbit/s local area networks, broadband MAN networks and even broadband wide area networks are widely used. Whether it is Intranet, exclusive, or residential intelligent networks, it is increasingly expanding to massive amounts of information, it is forcing people to transmit audio, video, data and other information in the network system more and more demanding. With the rapid development of Internet, the use of e-commerce, e-government, e

The author office used a common two-layer switch, has been silent for us for several years, so far there has been no accident. However, recently, the author of the local area network computer room has a switch suddenly strange phenomenon; taking into account the particularity of the fault phenomenon, the author used a special method to exclude, now the specific troubleshooting process is written out, I hope
The Cisco3550EMI switch is used as an instance of the DHCP server project, and the cisco3550emidhcp
Configuration of Cisco3550EMI switch as an instance of DHCP server Engineering
Network Environment:
A 3550EMI switch is divided into three VLANs. vlan2 is the network where the server is located. It is named server, IP address segment is 192.168.2.0, subnet mask: 2
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

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
The following article is an effective description of the ethernet switch parameter configuration problem, the switch according to the work protocol layer can be divided into a second layer of switches, third-tier switches and layer fourth switch, according to whether or not to support the network management function can be divided into network-oriented
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 switch devices and exchange and process data through these devices, the working status of a vswitch has a direct impact on the ove
First, the switch types are divided into low-end (SOHO-level) and high-end (enterprise-level ). An important difference between the two is the low-end switch. Each physical port is a logical port, while the high-end switch binds multiple physical ports into one logical port for configuration. In a cisco Network, the switch

the requirements of policy-based networking, advanced QoSQualityofService: service quality) and other service improvements. The huge market potential has greatly stimulated significant investment by manufacturers in key network equipment, so that in a very short period of time, the emergence of a traditional second-layer switch, to the Advanced Layer-3 Switch, to the latest layer-4 or even layer-7
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-
