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;

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

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

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

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
