vlan segmentation

For static and dynamic vlan configuration code instances of Huawei switches, there are many methods for configuring vlan of Huawei switches. Below is a sample code for vlan configuration of Huawei switches, I hope it will be helpful to the fans. either static or dynamic must be selected, followed by the vlan configurat

VLAN (virtual local area network), is based on the Ethernet interactive technology to build a fictitious network, can either divide the same physical network into multiple valn, can also cross the physical network barriers, users in different subnets to the same VLAN. Figure 2 is an example of a VLAN partition. Figure 2 There are many ways to implement VLANs,

The switch is not designed to be used as a security device, and its function is still to improve network performance. If the switch is to be part of the security mechanism, if the switch is to be properly configured first, then the manufacturer of the switch will have a complete understanding of the basic standards of the switch software and the implementation of these standards.If you have strict network security requirements, or do not use a shared switch, you should use a dedicated switch to

Recently, I have participated in many discussion and evaluation activities on hospital network solutions. Almost all hospital solutions use VLAN technology, however, I found that VLAN design in most solutions has a common and fatal defect, that is, the core of VLAN spanning network. This article will talk about your views on this issue for your reference.

We know that the traditional LAN Ethernet uses a carrier-monitored multi-channel access (CSMA/CD) method with conflicting detection. In CSMA/CD networks, nodes can use the network at any time they have data to send. Before the node transmits data, it "listens" to see if the network is busy. If not, the node begins to transfer the data. If the network is in use, the node waits. If two nodes are listening, without hearing anything, and starting to use the line at the same time, there will be a con

When you configure VLANs in a virtualized environment, you need to understand the differences between VLANs and virtual VLANs on the physical switch to better configure the network.First look at the link type on the physical switch.Three types of links on the upper port of the switch: Access, trunk, Hybird.A port of type access can only belong to 1 VLANs and is typically used to connect to a computer's port;Trunk type port can allow multiple VLANs through, can receive and send multiple

With the popularization of Switch Applications, VLAN technology is also widely used. As we all know, VLAN technology is mainly used to combine computers distributed in different geographic locations into a logical network as needed, while VLAN division can narrow the broadcast domain, to improve the network transmission speed, because computers in different VLANs

A vswitch is not designed as a security device, but is still designed to improve network performance. If you want to add a vswitch to the security mechanism, make sure that you configure the vswitch correctly, second, the switch manufacturer must fully understand and fully implement the basic standards of the switch software. If you have strict requirements on network security and do not use shared switches, you should use dedicated switches to Ensure network security. If a vswitch must be share

1 VLAN description the Chinese name of a VLAN (VirtualLocalAreaNetwork) is a virtual LAN. VLAN is a new data exchange technology that logically divides LAN devices into network segments to implement virtual working groups. This emerging technology is mainly used in vswitches and routers, but mainstream applications are still in vswitches. But not all vswitches 1.

Vswitch Port Vswitch ports can be divided into the following two types:Access Link)Aggregation Link Trunk Link)Next, let's learn the characteristics of these two different ports in sequence. First, we will learn "Access Links ".Access Link The access link refers to the port "only belongs to one VLAN and forwards data frames to this VLAN. In most cases, the access link is connected to a client.Generally, the

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 segment. Recently, more and more topics have been related to VLANs. Many people have expressed great interest in VLAN u

The emergence of Virtual lan vlan breaks the many inherent concepts of traditional networks, making the network structure flexible, convenient, and free to do as you like. VLAN divides user logic into working groups with relatively independent functions based on functions, applications, and other factors without considering users' physical locations, each user host is connected to a switch port supporting

Lab Requirements:The dual-core architecture combines three-layer switching technology with VTP, STP, and Ethernet channels to achieve high-speed network conversion, high availability, high reliability and redundant backup functions, mainly for the network of dual-core topologies.Experimental design:1. Configure VLANs on the switch to control broadcast traffic.2. Configure the Ethernetchannel between the 2 three-layer switches to achieve high-speed interoperability between the three-layer switche
