vlan segmentation

Ask your boss, younger brother, who has just started to access the kernel. Now he is looking at the implementation of VLAN in Linux. 1. Where can I find information about VLAN implementation?All the information I have here is about bridge. I have little knowledge about VLAN. Can anyone with information share it? Thank you :) 2. Relationship between

In the wireless network composition, the use of a lot of equipment is worth a detailed understanding. So today we're going to talk about the problem of VLAN wireless internet switch failures. The following is a netizen's experience sharing: Unit one office area where the two departments VLAN appeared a very strange problem, some websites on the internet can be normal access, and some sites are inaccessible;

VLAN is a virtual network, VLAN is divided into three ways: based on port, based on MAC address and ip-based address. In practical applications, the role of virtual network is similar to the division of different working groups, that is, the virtual network can not directly communicate with each other, but must be forwarded through the router, which to some extent improve the security performance of the ent

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

First, the basic knowledge: 1 type of VLAN: 1. Local VLAN: Members of the same VLAN are on a single switch; 2. End-to-end VLAN: Members of the same VLAN are dispersed to different switches; 2 The advantages of VLAN: 1, contro

Baidu keyword algorithm uses the word segmentation algorithm to analyze keywords. This can make our keywords more accurate and make our seo optimization work more effective. Understanding Word Segmentation technology is of great significance to SEO work. You can analyze keywords from a scientific perspective and propose keyword deployment strategies. If the positive maximum matching algorithm is correct, it

// Chinese word segmentation is the foundation of the Chinese search engine. It is mainly used in information retrieval, information mining, Chinese and foreign translation, Chinese proofreading, automatic clustering, automatic classification, and many other aspects. // This is the C # version I modified by referring to the VC example. ^ Using system;Using system. text;Using system. collections;Using system.

and Google, are not publicly available as search engine service providers of commercial companies. we can regard the existing search engine as a black box. By submitting input to the black box, we can judge the output returned by the black box and roughly judge the unknown technical details in the black box. Query Processing and word segmentation are essential tasks of a Chinese search engine, baidu, as a typical Chinese search engine, has always

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

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. Networking scenario: G
