switch vlan tagging

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,

Basic knowledge of VLAN division experiment: VLAN is short for Virtual Local Area Network (VLAN), which is a logical Network divided on a physical Network. This network corresponds to the L2 network of the ISO model. VLAN division is not limited by the actual physical location of the network port. A

Cisco's VLAN implementations are typically port-centric. The port connected to the node will determine the VLAN on which it resides. There are two ways to assign a port to a VLAN, which is static and dynamic, respectively. The process of forming a static VLAN is the process of assigning a port to a

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; assu

First, the generation of Super VLAN backgroundIsolate-user-vlan successfully solved the problem of reducing the number of VLANs, and also realized the sharing of three-layer gateways to some extent. But it also has a problem with MAC address duplication that consumes MAC address table entries, and the technology itself belongs to a two layer VLAN technology.In a

Huawei s5700 switch vlan settingsCurrently, there are several Huawei s5700 switches, common switches, and tp-link routers. 1. The tp-link router connects to the Internet. 2. The s5700 switch divides vlan. 3. Common switches are connected to VLANs and PCs. The following figure shows the network topology. The s5700 has a

Currently, virtualization is widely used. Generally, a physical host can create multiple virtual machines on a physical host after installing VMware ESXi or Hyper-V Virtual Machine Software, in addition, each created virtual machine can provide external services like the original physical machine, which can undoubtedly make full use of server resources to save power and space. But when most of our friends use virtual machines, there is also a problem: the physical host performance is high enough

Technical standards for VLANs IEEE 802.1Q was formally promulgated by IEEE Commissioners in June 1999, and the earliest Vlna technology was proposed by Cisco (Cisco) companies in 1996. With the development of the past few years, VLAN technology has been widely used in large and small enterprise networks, becoming the most popular Ethernet LAN technology at present. This article is going to introduce one of the most common

I. Lab Objectives Master the configuration of the switch tag VLAN; Master the basic configuration methods of layer-3 switches; Measure the test taker's knowledge about how to configure VLAN routing for a layer-3 switch; Layer-3 switches are used to implement inter-
