different switches

Currently, most enterprises in China generally access their networks through the backbone networks of China Telecom. They can only complete some basic information exchange functions, it cannot meet enterprises' complex network application requirements, such as handling diversified businesses, rapidly increasing branches for information exchange, and increasing information exchange volume. Therefore, building a core exchange network has become one of the top priorities of large and medium-sized e

uses a VLAN, and a VLAN is also available on the cliff. Linghu rushed to the cliff and Don't be sad. Finally, the world is quiet. Relying on the router of Zuo Leng Chan, Ling Hu Chong can still give it to Xiao Shimei on the Internet every day. Tell stories and chat. The introduction of LAN switches enables dedicated bandwidth between network nodes. However, for layer-2 broadcast packets, layer-2 Communication Broadcast on each network node. At the sa

Theoretical learningproblem 1 : How does the switch work? By learning the computer MAC address of each interface, it realizes the data communication of each computer, and the routing table of the router is similar, the switch is realized by the Mac-port mapping table.problem 2 : Two layer switch, three layer switch, router difference? Two-layer switch: For switching, LAN, WAN switching onlyLayer Three switch: Also known as the routing switch, with the dual functions of routing and switching, onl

Huawei three-tier devices can be IP and Mac binding, but a large number of that is sacrificing the cost of equipment performance, and sometimes attacks and network failures are easy to cause greater trouble. Moreover, the price of three-tier equipment is not all enterprises can buy at will. How to do Mac binding on two-tier low-end products to prevent the impact of ARP on the network. Step One: Enter port set E0/8 Port Mac learning number set to 0 (red for commands and parameters that must be

forwarding speed is fast, but it also forwards the wrong data packets. Extended Functions When you go to the market to ask about the price of the switch, you will find that there will be a huge price gap between different models for switches with the same number of ports produced by the same manufacturer. This is because various vendors have developed many extension functions for

Many SME internal network structures are simple, with only one switch connecting all employees and servers together and then accessing the Internet through fiber optics. Of course, in order to ensure the security of some hosts and split the internal broadcast packet to improve the network transmission speed, take such as partition VLAN, the allocation of different subnets to achieve. By partitioning VLANs, clients on

, centralized management of user authentication and security policies, and tracking and maintenance during roaming. In addition to the AP quantity management parameter, you should pay special attention to AP management functions such as automatic AP discovery, remote AP restart, illegal AP interception and location. In particular, the identification and positioning of illegal AP is not available or difficult to implement in traditional methods. Users should compare and analyze

When you create a virtual machine, your own network card needs to be bridged, and the virtual switch is usedVirtual Switch: Standard switch, distributed Virtual Switchfeatures offered by virtual switches : network bridging, online migrationStandard switch : Virtual Switch configuration for a single host, created on an ESXi host, is not visible on another ESXi hostDistributed Virtual Switches : Created on vc

other end. This enables the load balancing on several firewalls, so that the firewall can run in parallel, extending the performance of the firewall and eliminating the possibility of a firewall becoming a single point of failure. Unlike traditional packet switches, web switches have the ability to maintain different TCP sessions that are transmitted over Ethern

Asymmetric switches are still commonly used. So I studied the common application scenarios of asymmetric switches and shared them here. I hope they will be useful to you. Asymmetric switches are the first choice for enterprises that have funds and are unable to purchase high-end switches to improve network performance.

Layer-3 switches are commonly used. Here we mainly analyze the differences between layer-3 switches and routers. Here we will share with you, hoping to help you. In recent years, with the rapid development of Internet/Intranet and the wide application of the B/S computing model, the cross-region and cross-network business has experienced a sharp increase. The industry and users are deeply aware of the bottl

Bkjia.com comprehensive report: a stack switch connects several switches through a dedicated stack module to increase the port density of the network access layer exponentially. Some Manufacturers' switches can be managed as a network element after being stacked, which simplifies the network structure. Advantages of Stackable Switches Stackable

appear on the second layer of the network, the route is also routed to the whole multicast tree. With the large video traffic, it is difficult to distinguish between normal traffic and abnormal traffic. Therefore, it is more difficult to control multicast. In short, applications in the LAN may be exploited by viruses. If abnormal traffic is not effectively restricted, the network bandwidth and network devices will consume resources. Therefore, it is particularly important to add intelligence fo

Use Huawei ENSP and basic configurations of Huawei SwitchesHuawei switches are currently in very large Use in China. As we all know, the Network principles are the same. network devices of different brands only have different configuration methods, now I will teach you how to use some basic Huawei switches. And the use

Department, then how do they supervise it? This is the Port mirroring feature on the device. According to the author's knowledge, some savvy Internet cafes owners will adopt two systems, one end to the regulatory department, the other end connected to different broadband lines and switches to avoid being supervised.3, the choice of functionSwitches with management capabilities include VLAN partitioning and

As the main connection device of LAN, Ethernet switch becomes one of the most popular network equipments, meanwhile, with this kind of rapid development, the function of the switch is continuously enhanced, then the replacement of switch port and the connection port of various special equipment are added to the switch continuously. This also makes the switch's interface types become very rich, in order to give you a clearer understanding of these interfaces, we have compiled a special article on

As compatible with the latest Ethernet technology, Gigabit Ethernet is not only Ethernet "high-speed pirated", Gigabit Ethernet for the first time to put forward the million Gigabit wide area Ethernet technology, the first time to achieve a private network to the public network integration. Similarly, as the core device of the network, the Gigabit Ethernet switch is also not only supporting Gigabit access modules on existing Gigabit Ethernet switches,

Tiered switches can multiply the port density of the network access layer by connecting several switches through a dedicated stacking module. Some manufacturers ' switches can be managed as a network element after stacking, which simplifies the network structure. Advantages of Stackable Switches Stackable

Softswitch is a key technology for implementing next-generation networks. Media Gateway controller is a device that uses Softswitch technology to implement call control. This article mainly introduces the function and system structure of the Media Gateway controller, and discusses a solution for evolution from a circuit switch to a media gateway controller. I. SoftSwitch and media gateway Controller　 Softswitch is the core of the Next Generation Network NGN) to implement call control. It provide

called AC. We also use the word "WTP" to refer to AP (including fat, thin, or moderate ). The IETF's Wireless Access Point Control and configuration (CAPWAP) team is defining interfaces and protocols between the AP and Its controlled WTP. This section uses the CAPWAP framework to describe the interfaces between AC and WTP. [3, 4, 5] The following functions can be implemented through an interface between the AC. WTP and the AC through a L2 (Exchange) or l3 (route) network: ◆ Discover and select
