As a new generation of network technology, VLAN provides a good solution to the problems of flexible configuration of network sites and network security, the following describes how to update a VLAN on a layer-3 switch. The filter service is used to set boundaries to restrict Frame Forwarding between members of different VLANs and between different protocols using a single MAC address and a group of MAC add

Many people may not have a special understanding of setting policy routes. So I have studied VLAN-Based Configuration Policy routes. Here I will share with you, hoping to help you. With the popularization of networks, how can small-sized enterprise local networks spend less money to implement more complex network functions in the case of a shortage of funds to meet people's needs for higher network functions, it is a concern of network technicians. In

from a group of MAC addresses. GMRP transmits such group information between vswitches on the Internet, so that vswitches can update their filtering information to implement extended service functions. A vswitch has the filtering service and extended filtering service without any configuration. Because the old vswitches, hubs, and routers do not support dynamic multicast address filtering, the corresponding ports connected to them need to be configured with extended filtering. The switch filter

VLANThe typical configuration process is as follows: Networking Diagram Figure 1-1 port-based VLAN networking Application Requirements As shown in Figure 1-1, Switch A and Switch B connect Host1/Host2 and Server1/Server2 used by different departments. To ensure data isolation between departments, you must divide Host1 and Server1 into VLAN100 and Host2 into VLAN200. Set the description characters for the two VLANs to "Dept1" and "Dept2" respectively

Recently, a number of Cisco ucs c Series servers have been added. After two weeks of deployment and installation, the server can finally be tested. This document briefly introduces the network configuration of the Operating System (centos 6) in the Cisco UCS server. It can be simply considered that this article describes the network configuration of a physical server connecting the NIC to the trunk mode port of the Upper-layer switch with a network cable. The physical connection topology is show

VLAN network structure of Small Enterprises As we know, the structure of an enterprise is complicated. They have different departments. Next we divide VLAN networks of a small enterprise by department. Assume that a small enterprise network has a Finance Department, channel department, server area, and other departments. Because the number of computers in a small enterprise network is not very large, the

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

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.
