Full solution D-LINK Switch configuration in the enterprise network VLAN subnet usage, on the D-LINK Switch configuration problems, from the following aspects: from the enterprise network plan four VLAN subnet classification and structure, DES-3326SR Switch configuration process is introduced. The example below gives a detailed explanation. VLAN division should b

Article title: Implementation of VLAN and policy routing on campus networks of a university. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. I. network topology (shown in the appendix) and network planning: 　　 The vSwitch is Cisco2924, divided into three VLANs, VLAN10 for office use, VLAN13 for classroom use, VLAN

Note: The vlan number of a vswitch starts from VLAN 2 because the vswitch has a default VLAN, namely VLAN 1, which includes all users connected to the vswitch. The VLAN configuration process is actually very simple. Only two steps are required: 1) name each

Experiment: Huawei mux vlan configuration and management The following experiment is an experimental video teaching course designed by the author for "Huawei switch Learning Guide". Click here to view details: http://edu.51cto.com/course/course_id-2091.html The mux vlan function of Huawei enables layer-2 communication between different VLANs located in the same IP network segment (between all slave VLANs an

VLAN partitioning based on MAC addresses is divided into three types:First type: Manually configure the static Mac VLANSecond type: Dynamic trigger port joins static Mac VLANThird type: Dynamic Mac VLANThis document describes the manual configuration of the first static Mac VLAN; Environment: H3C ENSPFirst step: Build Vlan:vlan 100Step two: (VLAN mode) creates a

A typical LAN refers to a core switch with a three-layer switching function to connect several branch switches (not necessarily three-layer switching capabilities). We assume that the core switch name is: COM, branch switches are: par1, PAR2, PAR3, respectively, through the port 1 Ray module with the core switch, and assume the VLAN name is counter, market, managing ... The work to be done: A, set up VTP domain (core, branch switches are set up) B,

VLANIt is a protocol proposed to solve Ethernet broadcast problems and security. It adds VLAN headers Based on Ethernet frames and divides users into smaller working groups using VLAN IDs, restrict mutual access between users in different working groups. Each working group is a virtual LAN. The following describes how to implement static VLAN interfaces of a swit

Summary: In this article, we will discuss how to deploy the smoothwall proxy server in a typical campus network environment. This section mainly discusses how to configure Static Routing in multiple VLANs (because of other problems such as localization, update, Port Mirroring, and Backflow ). I have already demonstrated the situation clearly) Campus Network Topology Smoothwall Configuration:InternetIp: 202.98.30.69Mask: zookeeper without authorizationDG: 202.98.56.94DNS: 61.128.128.68 LAN: Ip: 1

VLAN (VirtualLocalAreaNetwork) is a virtual network built based on Ethernet interaction technology. it can divide a physical network into multiple valns or overcome physical network barriers, users in different subnets are allocated to the same VLAN. This article mainly introduces Python black hat programming 3.4 Cross-VLAN information. For more information, see

In the enterprise, to realize that all employees can communicate with the Internet, everyone using a public address is very unrealistic. Generally, the enterprise has 1 or several public network address, and the enterprise has dozens of, hundreds of employees. How do you want all employees to use the only few public network addresses to communicate with the Internet? Use NAT Technology!In the enterprise, there will be a number of departments, such as finance Department, technical department, eng

To address the limitations of traditional VLANs and ensure the security of network communication to a greater extent, many VLAN extension technologies have emerged in recent years, this article mainly introduces PVLAN, SuperVLAN, SVLAN and other typical extended VLAN technologies. 1 PVLAN Technology (Private VLAN) PVLAN divides

In a network topology with two switches, can the same VLAN communicate? The answer is yes !!The Chinese meaning of trunk itself is: trunk, and trunk? In other words, it can carry something. It also plays a bearing role in the network, and it can carry multiple VLANs, enables communication between the same VLAN of different switching devices. As you can see, trunk also has its own structure. Since trunk is a

Principle 1: VLAN Based on ports-physical ports on VLAN switches and internal PVC (permanent virtual circuit) ports. Advantage: it is easy to define VLAN members. You only need to define all ports as corresponding VLAN groups. Disadvantage: if a user leaves the original port to a port of a new switch, it must be redefi
