Cisco single-ARM routing configurationOne-arm routing, which is to set up multiple logical subinterfaces on the router, one VLAN for each sub-interface. The data on each sub-interface is passed on the physical link to be labeled encapsulated. Cisco devices support ISL and 802.1q (dot1q) protocols. Huawei only supports 802.1q.The difference between dot1q and ISL: dot1q is a generic VLAN protocol model for va

H3C layer-3 Switch configuration: analyzes VLAN code instances. Currently, there are a lot of people using layer-3 switches, and maintenance of switches has become a problem that cannot be ignored. Only the three-tier switch is configured, which not only saves your time and effort on accessing the Internet, but also brings more highlights to your network life. Note: There are three VLANs, 192.168.10.0; 192.168.20.0; 192.168.30.0, And the subnet mask i

experiment six using three-layer switch to implement inter-VLAN routingFirst, the experimental target Mastering the configuration of the switch tag VLAN Master three layer switch basic configuration method; Master three-layer switch VLAN routing configuration method; Inter-VLAN communication throug

Router and three-layer switch experiment Demo--a gateway that acts as a two VLAN--Hundred dishes background : We know that routers have routing capabilities, so you know how to configure two gateways on a router interface (such as a two VLAN gateway)? Note that it is on one interface instead of two, and we sometimes use the three-layer switch as a router, so how do we configure the three-tier switch at this

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

Device Connection: Router ex-r eth0 connection light cat dial, eth3 connection switch gs105e, switch gs105e ETH3 connection wireless APRequirement: Router dial-up Internet, wireless network with different SSID can connect different VLAN, and 4th Port of switch connects Nas, belong to one of VLANThat's about the length of the picture.

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

In a well-established LAN, how to implement LAN switch maintenance and testing skills, as well as problems encountered during LAN switch debugging, I found some related solutions on relevant forums, share with you for mutual learning and communication. In an IP address-based VLAN, the new site does not need to perform too many configurations when accessing the network, and the switch automatically divides it into different VLANs based on the network a

When we first started the network, we wrote a little bit of things we learned today for everyone to throw bricks.Topology:Lab objectives:(1) Step 1: divide four VLANs and place corresponding ports into vlan numbers.(2) Step 2: implement mutual ping between four VLANs(3) in step 3, sales, tech, and manage cannot communicate with each other, but can communicate with the server.Implementation process:Step 1: divide the

It is easy to implement the vlan configuration functions of Huawei switches. In the current vlan configuration of Huawei switches, some people may not understand the specific vlan configuration methods of Huawei switches. It doesn't matter. I have read the following parameters, you will also become an expert. This is the first interface displayed when you connect

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;

Programmers are lazy, you know. Ten years of life and death two boundless, write procedures, to the dawn. Thousand lines of code, where the bug is hidden. Even if the line and how, toward the change, Xi heartbroken. Lead a new idea every day, change every day, daily busy. Care without words, only tears thousand lines. Every night the lights are dim, the night is hard to sleep, and overtime. Gossip less, directly on the code: Hua San switch operation command Enter user name return, enter passwo

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

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
