vlan segmentation

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

VLAN lab questions: Answer Process (1) full connectivity between devices with the same VLAN 1. Create vlan2 and vlan3 on SW1 and sw2 respectively. The command is as follows: SW1 # VLAN DatabaseSW1 (VLAN) # VLAN 2 2. Route the corresponding interfaces to the corresponding

Voice VLAN concept and networking concept: the so-called voice vlan uses vlan to identify a packet as a Voice packet, and the packet carries 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 priorit

Switch Port vlan mode Ø the Acess port receives a packet to determine whether there is any VLAN information: If there is no vlan information, the PVID of the port is entered and the switch is forwarded. If yes, the packets are discarded directly (default) Ø send packets on the Acess port: the VLAN information of the pa

Inter-VLAN RoutingMulti-layer switch between VLANs ip Address: 1. for local or end-to-end VLANs, the recommended number of hosts in a single vlan is 100-200.2. for layer-3 point-to-point interfaces, we recommend that you use a 30-bit mask when designing the p level. Devices that implement vlan routing: 1. any layer-3 Switch 2. any external router with interfaces

Three-layer switching technology: two-layer switching technology + three-layer forwarding technology. It solves the network segment in the LAN, the network segment must rely on the router to manage the situation, to solve the traditional router low speed, complexity caused by the bottleneck problem.650) this.width=650; "Src=" Http://s1.51cto.com/wyfs02/M01/84/63/wKioL1ePKkTAgqs8AACyLCFWuCA902.png-wh_500x0-wm_3 -wmp_4-s_366222421.png "title=" three-layer switching

, and completely using ASIC hardware to achieve routing and switching at line speed, the latter represents the fast ip of 3com, and the virtual fast Security Network of cabletron. The method used is to route the network at the first layer, then, the second layer switches the end-to-end network stream data group. This is the policy of "one route, then switch. The powerful functions of the layer-3 Exchange router are as follows: (1) routes are calculated based on the L3 protocol. The supported ro

In the two-layer network, when transmitting two beginning, it needs to be forwarded with the outer VLAN of the message, while the outer tag of the user network is usually inconsistent with the VLAN of the carrier network, so the VLAN stacking and VLAN mapping and dot1q tunnel etc. Unlike

This paper introduces some techniques of improving system performance, such as segmentation, segmentation, instance segmentation, and physical storage segmentation.This article mainly explains the design of the database, because a good data structure, the overall system operation is too important, please look at the contents of this article.Referring to the perfo

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
