There are many things worth learning about layer-3 switching technology. Here we mainly introduce the comprehensive comparison between layer-2 switching and layer-3 switching technology. In today's network construction, the layer-3 switching technology is recognized and prai

There are many areas worth learning about the application layer switch. Here we mainly introduce the structure and practical application of the application layer switch, and the Exchange Technology is moving towards two directions. One direction is that the speed is getting faster and faster, and it has jumped from 1g

With the rapid development of China's exchange industry, it also promotes the upgrade of the Third-layer switch technology. Here we mainly analyze the technical trend of the low-end third-layer switch. In the switch market, layer-

Layer-3 switches are quite common, So I studied how to correctly select the layer-3 Switch. Here I will share it with you, hoping it will be useful to you. The current vswitches generally have the "routing" function, which makes it hard for many enterprise users to figure out whether a vswitch can be used instead of a vro. How can I select a vswitch?　In fact, the

In fact, the essence of a layer-3 switch is a layer-2 switch with the routing function. The routing mainly belongs to the network layer function in the OSI reference model, so the layer

Currently, few second-layer switches are used, mainly because of their performance limitations. We believe that with the development of the communication industry, switches with better performance will continue to emerge. In today's network construction, layer-3 switches are recognized and praised by users for their efficient performance and superior performance/price ratio. At present,

The layer-3 Switch has become one of the most important devices in the network. Here we analyze the technical principles of the layer-3 switch in the exchange technology, a device with the layer-3 switch function is a

legality of user access. IEEE 802.1x is a good medicine to solve this problem. It has been integrated into a layer-2 smart switch to complete access security review for users. 802.1x is a newly standardized LAN access control protocol that complies with the IEEE 802 protocol set. It is all called Port-based access control protocol. Based on the advantages of IEE

choices, the two-layer switching, three-layer switching, and seven-layer switching technologies are superior to each other. What environments are they applicable? Traditional layer-3 Exchange Technology Layer-2 switching technolo

cannot connect the LAN to the WAN or the Internet, because the routing protocols supported by layer-3 switches are very limited. After all, this is not its main function. We know that on the LAN, a layer-2 switch identifies the packet sender through the source MAC address and forwards the packet according to the desti

options for L3 protocols to meet the needs of various advanced network applications. 2. Comparison with L2 Switching The distributed L3 switch supports popular routing protocols and organically combines the advantages of L2 switches with vrouters. l3 switches can control IP addresses, making it easier to build large-scale local area networks. 3. Differences from centralized

A layer-3 switch does have a certain "routing" function, which can implement different subnet connection functions. However, it must be noted that its routing function is much weaker than that of a router, in addition, a layer-3 switch can only use one network. Generally, it is only the interconnection between LAN subn

1. Functions of the data link layer Implements data error-free transmission. It receives raw data from the physical layer to form frames and bit groups) and transmits data between network devices. The frames contain the physical addresses of the active and target sites, the device that works on this layer has a switch

analyze the performance indicators of various products. However, for example, switching capacity Gbps) and Board bandwidth Gbps), processing capability Mpps), throughput Mpps) and many other technical indicators, you 'd better grasp the "throughput when the configuration is full", because other technical indicators users are generally unable to measure, only throughput is an indicator that users can use Smart Bits and IXIA testing instruments for direct measurement and verification.

A typical LAN is to connect a core switch with a layer-3 Switch to several Branch switches (not necessarily with layer-3 switching ). We assume that the core switch name is com, and the Branch switches are par1, par2, and par3 respectively, which are connected to the core

Before learning about the features of a layer-3 Switch in an Internet cafe, let's take a look at what layer-3 switch is? Traditional switches work at the Layer 2 data link layer of the

use the 3rd layer switching technology with the routing function, or is it possible to use a layer-3 Exchange Technology with a high level of network services? In the trade-offs of these technical choices, the two-layer switching, three-layer switching, and seven-layer swit

Since Layer-3 switches can be considered as composed of routers and common switches, You can first try to install some modules with routing functions during assembly, in this way, there is a layer-3 Switch rich in routing functions. Its functions are equally powerful. Recently, the price of vswitches has been greatly reduced. Some models of some domestic brands h

Layer-3 Switch for Cisco switches Although single-arm routing solves the communication problem between different VLANs, it also has its fatal defects: -The single arm itself is the Backbone link of the network, which is easy to form a network bottleneck. -The sub-interface relies on physical interfaces, and the application is not flexible -You need to view the route table for each vlan forwarding, wasting
