VLAN and the IEEE 802.1Q VLAN implemented by LinuxThe concept of VLANs Introduction to VLAN Technology Vlanvlan overview Ethernet is a data network communication technology based on CSMA/CD (Carrier sense multiple access/collision Detect, carrier listening multi-access/collision detection), which can cause serious conflict and broadcast flooding when the ho

A typical LAN is to connect a core switch with a layer-3 Switch to several Branch switches (not necessarily with layer-3 switching ). We assume that the core switch name is com, and the Branch switches are par1, par2, and par3 respectively, which are connected to the core switch through the light module of port 1; assume that the vlan names are counter, market, and managing ...... Work to be done: A. Set vtp domain (both core and branch switch) B. Con

Configuration of Virtual LAN (VLAN), lan vlan Figure 1 Experiment Topology Lab content: (1) Name the switches SWA and SWB respectively. (2) divide Virtual LAN VLANs and statically divide ports into valn. First, use two methods to divide VLANs. L vlan division in global mode: This method is used to create three VLANs on the SWA switch:

//--------------------------------------------------------------------------------------What do you mean by VLAN transmission?It doesn't matter what you come up with, I'll let you through. This explains the type of data, no matter what the data.Why there is the concept of VLAN transmission.The purpose of the original VLAN is to isolate, the data of different VLAN

1. What is a VLAN?VLAN is a virtual local area network, which means that the sites in the networks do not rigidly adhere to the physical location, but can flexibly add a network technology in different logical subnets as needed.Virtual local area network based on switched Ethernet in switched Ethernet, the VLAN technology can be used to divide the physical networ

Many readers are not very clear about the formation and working principle of VLAN 《Cisco/H3C Switch configuration and management manualRelated content in the book.8.1.1 understand VLAN formation and working principlesA VLAN is a logical segment of the switching network divided by function, project group, or application

Inter-VLAN Routing 3 ways: One physical connection per VLAN, one-arm routing, three-layer switching.One physical connection per VLAN: A separate interface is assigned to each VLAN on the router, and a physical link is used to connect to the Layer two switch. When the host between the VLANs needs to communicate, the dat

Recently focused on the next VLAN division, found that the VLAN divided into 2 kinds, usually used in the work called the local VLAN, there is a kind of called end-to-end VLAN, generally used in more than 10 or dozens of switch-sized enterprise network.Baidu through the difference between the two, the description is no
