An improper port connection between switches in the Ethernet may cause a network loop. If the related switch does not enable the STP function, this loop will lead to endless repeated packet forwarding, forming a broadcast storm, this causes network

There is a virus in a machine in a LAN. If the virus is not eliminated and isolated in time, other machines will soon be infected with the virus. Once the virus is infected with the whole site machine, the network anti-virus will be disabled, and a

I. Why do I need a second layer? 1. challenges posed by virtualization to data centers The traditional three-tier data center architecture is designed to cope with the service client-server application's vertical large traffic, and enables network

Vswitches can be divided into backbone switches and desktop switches based on different application scenarios. backbone switches are mainly used for enterprises to build backbone networks, while desktop switches are designed to directly connect to

For complete syntax and application information about this chapter, seeCatalyst 3550 Multilayer Switch Command ReferenceAnd Cisco IOS Interface Command Reference For Release 12.1. Understanding Interface Types This section describes different

The ethernet switch is a very important device in the network. Many people may not know the data interface type of the Ethernet switch. It does not matter. After reading this article, you must have gained a lot, I hope this article will teach you

The distributed layer-3 switch is still quite common. So I studied and analyzed the practical application of the distributed layer-3 Switch. Here I will share it with you and hope it will be useful to you. With the in-depth development of modern

Assume that in 2023, you are sitting in a flying car with your former colleague. You two have discussed this topic-what has happened to cloud computing in the past? As a buzzword, just like all other buzzwords, cloud computing will eventually be

The switch configuration file is like the registry we use in daily use. If the registry is damaged or the configuration is inaccurate, the operating system cannot be started or run stably, once a problem occurs in the vswitch configuration file, the

Network-Based Application Recognition (NBAR) indicates Network Application Recognition. NBAR is a technology that can dynamically search for protocols in Layer 4 to Layer 7. It can not only control static and simple network application protocol

In order to help enterprise users better understand the meaning of layer-3 Switch, understand the various new technologies supported by the leading layer-3 switch in the current market, and their position and role in the next-generation smart

Broadband routers are currently one of the most commonly used routes. So I have studied the installation steps and problems that need to be paid attention to during the installation of broadband routers. I would like to share them with you here and

LAN routers are quite common, So I studied the frequent disconnection problem of LAN routers. I would like to share it with you here and hope it will be useful to you. Several companies in the unit building have their own LAN, and each lan has more

  1. show cpu usage The PIX only has one CPU to complete all the work, from the processing package to writing debug information to the console. The process that consumes the most CPU resources is encrypted. Therefore, if you want to encrypt data

In traditional Data Center Server area network design, the L2 network is usually limited to the network convergence layer. By configuring VLANs for cross-aggregation switches, the L2 network can be extended to multiple access switches. This solution

One day, when I was restricted by many secular rules and could not do what many normal people could do, I suddenly felt: people should not have come to this world! Since we fell into the ground, we have been destined to suffer a lot in our life...

With the development of wireless network technology, many of us are already very familiar with the network architecture, so we are not very clear about the differences between Wireless AP and wireless routing. Here we will introduce it to

The development of wireless networks is quite mature, but for our wireless network users, we will give a detailed introduction to how to set various wireless network security problems. As the prices of low-end wireless network devices continue to

Traceroute command usage instance traceroute is the routing tool used to track data packets arriving at the network host. traceroute is the gateway tool used to send data packets between the host and the target host. The principle of traceroute is
