With the development of enterprise network applications, people are no longer satisfied with the desktop network speed of 100 MB. Many people are looking for faster LAN connection technologies, using Gigabit Ethernet or faster 10-Gigabit technology.

1. Ethernet was originally based on coaxial cable. In, Xerox \ inter and DEC proposed DIX.2. In, the IEEE Standard was proposed.3. CSMA/CD communication process, transmission-listening-interference-random wait-transmission.4. Traditional Ethernet

1. Create a vlan on the vswitchCreate a vtp management domainTo create a vlan on a vswitch, you must first create a vtp management domain so that it can verify the current vlan on the network.The Catalyst 4000 Series Switch module only supports 802.1

Due to work requirements, I want to route a port to multiple VLANs if I do not want to start the routing. The purpose is as follows: 1. Isolate ports that do not want mutual access. For example, two Departments) 2. Route all ports to all VLANs. Such

We know that the traditional LAN Ethernet adopts the CSMA/CD method with conflict detection. In the CSMA/CD network, nodes can use the network whenever they have data to be sent. Before a node transmits data, it performs a "listener" to check

VLAN Implementation Mechanism After understanding why VLAN is needed, let's take a look at how a vswitch uses VLAN to separate broadcast domains.First, on a L2 Switch without any VLAN, any broadcast frame will be forwarded to all other ports except

Configuration example:C3550 # show running-configBuilding configuration...Current configuration: 4143 bytes!Version 12.1:No service padService timestamps debug uptimeService timestamps log uptimeNo service password-encryption!Hostname C3550!Ip

Currently, a large-scale LAN or man can be constructed in two structures: a standard TCP/IP structure based on a distributed Router or an Internet structure; the other is a VLAN-based fully switched network structure. A VLAN is a virtual network

By default, VLAN communication is not allowed between VLANs. To achieve inter-VLAN communication, you must use a router. However, a router is a layer-3 device, which not only involves hardware design but also software design, therefore, it is

The popularization and application of computer networks are changing our world and our way of thinking and life. With the continuous development of network technology, we are more concerned about how people use computers and how they use networks to

With the advent of the information age, especiallyWTOChina's enterprise development has entered a new period. It also means that the enterprise informatization construction that represents the competitiveness of the future must take a new step, it

With the development of networks, databases and related application technologies, especially the Internet and Intranet, the world is entering the Network center Computing Network Centric Computing era. The logistics industry has also evolved from

The configuration is completely correct and has been running for nearly half a year. The main idea is that everyone can learn together and use practice to consolidate their learning results. If you have any questions, I believe they can solve all

I. OverviewIn 1993, LAN switching equipment emerged. In 1994, the exchange network technology boom began in China. In fact,Exchange Technology is a simplified, low-cost, high-performance and high-port intensive exchange product, reflecting the

In the application environment of a network, there are many ways and methods to manage the network. At the same time, different methods can be used to achieve this. The network management function of a vswitch is used to detect and control the users

With the rapid development of communication network technology, people's requirements for broadband and business are also growing rapidly. In order to provide users with more flexible and diverse existing businesses and new businesses, providing

The device is the Catalyst8540 CSR. ISL. VLAN. BVI is configured and HSRP is used. In these examples, the reserved IP address is used, and you need to replace it with the valid IP address you want when using the network.Instance 1:Related

With the popularization of home networks and computers, many home and SOHO office users have multiple computers. Many users complain about the insufficient number of device interfaces when using wireless routers or broadband routers. In fact, there

The development of the ADSL Router is very rapid, and there are also many problems. Maybe many people still don't know how to use the ADSL Router to prevent hacker attacks. It doesn't matter. After reading this article, you will certainly have a lot

A wireless router has a wide range of applications and has a strong role. By configuring a wireless router, you can build a wireless LAN. This type of wireless router is added due to network expansion. When you add this device to the original wired
