vxlan vs vlan

This document introduces how to divide 802.1Q VLANs based on examples.Example: as shown in the preceding figure, the marketing department and product department of a company set up network isolation. The two departments can access the Internet and servers of their respective departments, but mutual access between departments and servers of other departments is prohibited.In this example, the actual topology and port connection effect are as follows. This article describes how to divide VLANs bas

The so-called voice vlan identifies a packet as a voice packet, and the packet carries the voice data. In networks where voice messages and data packets coexist, vlan-based voice packets are identified to distinguish voice messages and data packets, and a higher priority is given to voice packets to ensure that voice data is preferentially served, low latency and low packet loss rate. Networking scenario: G

Bkjia.com Expert Clinic is a special topic on the BKJIA website. Each session has a subject and an expert. It aims to provide a timely and convenient communication platform for the majority of users, as soon as the topic was launched, it was well received by a large number of network engineers. The discussion on the topic was very enthusiastic. The topic "in-depth understanding of VLan configuration" recently discussed has an unprecedented atmosphere.

This article describes in detail the detailed steps and procedures of VLAN division, and tells readers a complete configuration process through a specific instance. Virtual LAN (VLAN) Currently, the backbone network technology we use when constructing an enterprise network is generally based on exchange and virtual networks. The exchange technology changes shared media to exclusive media, greatly improving

VLANTechnology divides networks into virtual LAN, which is also used to isolate network broadcast. However, the PC in the same VLAN is still in a broadcast domain, that is, communication between PCs in the same VLAN is unrestricted. In this case, you can use the MAC address-Based Access Control List to perform Layer 2 filtering on each port. The command is as follows ): Create access list 1100 in global mod

With the rapid development of information technology, especially the continuous improvement of computer and network technology, people's transmission requirements for the network are more and more high, in the competition, Ethernet with its high transmission speed, low consumption, easy to install and good compatibility, such as the advantages of becoming the first choice for modern enterprise network, VLAN technology is a good solution to the problem

The Chinese name of a VLAN (Virtual Local Area Network) is "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. However, not all vswitches have this function. Only the layer-3 or above vswitches o

As we all know, VLANs exist for convenience of management and security. How to Create a Vlan? Let me configure a simple Vlan network for communication between VLANs and between non-VLANs! The parameters are as follows: Vlan3: 172.28.255.255.255.255.0 Vlan5: 172.28.15.0 255.255.255.0 Vlan1: 172.28.16.0 255.255.255.0 Vlan4: 172.28.14.0 255.255.255.0 R. 11.11.1 255.255.255.0R. 11.11.2 255.255.255.0 The network

VLAN Technology: XEN creates an Intranet Steps: 1. Create a Network 2. Create a VLAN Several internal operations are involved when creating a VLAN. ● Create a Vlan object (① in the figure) ● Create a PIF (② in the figure) to connect the created VLAN (① in the figure) to t

Many SME internal network structures are simple, with only one switch connecting all employees and servers together and then accessing the Internet through fiber optics. Of course, in order to ensure the security of some hosts and split the internal broadcast packet to improve the network transmission speed, take such as partition VLAN, the allocation of different subnets to achieve. By partitioning VLANs, clients on different ports on the same switch

The VTP password settings and Huawei switch vlan configuration experiment results show you how to configure the vlan of a Huawei switch. Many people may not understand the vlan configuration of a Huawei switch, VTP transparent mode, VTP password settings, and V1, v2 integrated application. It doesn't matter. After reading this article, you will certainly have a l

First, let's take a look at what tpid means? Frames in the 802.1Q document of VLAN protocol are embodied in the following data packets: Here, the blue position is the 802.1Q header, and the specific meaning of each item is: Tag protocol identifier(TAG protocol ide

First, we need to understand the origin of VLAN and why such a technology is generated. This starts with the data exchange in the computer network. At the very beginning, our network was in the wild age. How did we exchange data, that is, simple media sharing, and everyone was connected to a line, then send data to each other, which will inevitably lead to a problem. There is only one way for everyone to compete, and there will inevitably be no confli

Learning essentials-the most comprehensive summary of VLAN learning notes (Free Download !) (It's a pity)-Linux Enterprise Application-Linux server application information. The following is a detailed description. [I = s] This post was last edited by ytitxw Recently, I have prepared my VLAN study notes, summarized all the knowledge points, and packaged them into pdf files for you to download and read.

Secrets: how to configure a VLAN on a vswitch When configuring a VLAN in a virtual LAN, I will introduce the VLAN configuration in the article, we will provide you with a learning direction for relevant knowledge. 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

After we have a detailed understanding of DHCP, we also know that it also has some service settings in the applications of a variety of routers and switches. Here we will focus on the configuration of dhcp relay. This time, we will explain the content of the dhcp server corresponding to the vlan interface configuration. ◆ Dhcp relay Configuration Dhcp relay configurations include: Configure the dhcp server corresponding to the
