layer 2 network switch

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

security. Therefore, the use of VLAN in the initial design of the network can bring great benefits to the future expansion of the network.VLAN partitioning by routers is a cost-effective method in small and medium-sized enterprises. However, VLAN partitioning by routers seriously affects the network performance of enterprises, therefore, layer-3 switches with ro

Third-tier switches have a lot to learn from the place, here we mainly introduce how to choose the third layer switch, the third layer of switches present a strong growth trend, is replacing routers in the LAN, its huge market potential is attracting a large number of domestic and foreign manufacturers to join the competition. It is gratifying that the domestic m

and find the most suitable path for data transmission in the network. In general, individual users have little need. A vro is generated after a vswitch, just as a vswitch is generated after a hub, so the vswitch and vro are also associated, and they are not completely independent of each other. Vro mainly overcomes the problem that vswitches cannot route and forward data packets. In general, the main difference between a vro and a vswitch lies in 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

bring great benefits to the future expansion of the network. VLAN partitioning by routers is a cost-effective method in small and medium-sized enterprises. However, VLAN partitioning by routers seriously affects the network performance of enterprises, therefore, layer-3 switches with routing functions are widely used in VLAN networks of large and medium-sized en

Advantages of layer-3 Switch Settings: high scalability and cost-effectiveness. layer-3 switch settings have good performance, such as high cost-performance ratio, high scalability, and security mechanism problems. This article also introduces several popular wireless routers on the market. In addition to excellent per

Currently, exchange routers are widely used. Many people may not understand the differences and connections between layer-3 switches and exchange routers. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. In recent years, with the rapid development of Internet/Intranet and the wide application of the B/S computing model, cross-region and cross-

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

Have you ever thought about manually creating a layer-3 switch? Here we will teach you how to create such a layer-3 switch, which is equally powerful. Recently, the price of vswitches has been greatly reduced. Some models of some domestic brands have fallen below RMB, which is almost the same as that of hubs. With the

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 IEEE802 protocol set. It is called Port-based access control protocol. Based on the advantages of IEEE802 LAN, it provides a method to authenticate and authorize users connecte

switch module still cannot avoid conflicts in the Ethernet environment, while the Matrix Type avoids conflicts during port switching.3. focusing on latency and latency jitter indicators, the enterprise intranet is almost a high-speed LAN. One of its purposes is to transmit large-capacity multimedia data such as audio and video, however, these large-capacity multimedia data packets do not affect information transmission due to long latency and packet

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
