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 lay
Security switches are worth learning a lot. Here we mainly introduce the three-layer meaning of Security switches. as the core of the entire network, users who access and access network information should be able to differentiate and control permissions. More importantly,Security SwitchIt should also work with other network security devices to monitor and block unauthorized access and network attacks. Security switches play an important role in the en
The distributed layer-3 switch is still quite common. So I studied and analyzed the practical application of the distributed layer-3 Switch. Here I will share it with you and hope it will be useful to you. With the in-depth develo
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
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

Comprehensive introduction to layer-3 Switch configuration instances: with detailed command explanations, have you ever encountered layer-3 Switch configuration? Are you familiar with the detailed commands? Does your
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-
At present, China's routing industry is developing at a high speed, and it also promotes the constant update and upgrade of routing technology. Here we mainly explain the connection methods of layer-3 routing switches. As for the stack of routing switches, not all vswitches are allowed, but stack modules are required. The stack of A vswitch is connected through a dedicated stack cable instead of a switching
The main function of a security switch is to forward data in the network. It can also ensure efficient network data forwarding when other factors interfere, with the advent of the Internet era, security issues have become an urgent issue. The existence of viruses, hackers, and various vulnerabilities makes security tasks extremely difficult in the Internet era. Vswitches play an important role in the enterprise network, usually the core of the entire

There are many things worth learning about layer-3 router switches. Here we mainly introduce the solutions to soft faults in layer-3 router switches. Two days ago, our company's network was upgraded, and the core device adopted the INTEL550 series L3 route switch. The 500 se
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
For example, simply using a vro, because of the limited number of interfaces and slow route forwarding speed, in general, in a network with a large volume of intranet data streams and requiring fast forwarding and response, for example, all three-layer switches are used for this work. As we all know, a router can connect to an enterprise LAN or a wide area network (such as the Internet), but it ignores another application of a router, that is, its LAN
The wide application of layer-3 switch technology enables dedicated bandwidth between network sites, avoiding unnecessary Collision Detection and error re-transmission, greatly improving work efficiency. What is the difference between it and other routing devices? What is the function? With these questions, let's take a look at its advantages. In order to adapt t
The following describes the principles and functions of a layer-3 Switch. A temporary switching path is established between the initiator of a data frame and the Target receiver, it only has the ability to process IP layer or even higher layer data packets. Currently, most
Lab objectives:1. Master the configuration of the switch Tag VLAN;2. master the basic configuration methods of layer-3 switches;3. Master how to configure VLAN routing for layer-3 switches;4.
For details about how to set the default mode of layer-3 Switch gateway, recently, many friends have been paying attention to the setting of switch gateway. Today, let's have a deep understanding of the techniques for setting the switch gateway! The new experience is waiting
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
