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
There are many things worth learning about layer-3 switches. Here we mainly introduce the anti-virus capabilities of layer-3 switches, and the anti-virus capabilities of layer-3 switches are also very powerful, especially when net
Layer-3 Switch Equipment is still quite common, So I studied how to identify the performance of layer-3 Switch Equipment. Here I will share with you, I hope it will be useful to you. With the gradual development of network applica
The processing of layer-3 data packets by the Gigabit route switch technology, I insist on writing notes every day. Record your experiences and put more time into your career. In the traditional sense, only the device that processes Layer 2 Data Forwarding is called a switch
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
Case:There are two PCs at the front-end. After Windows 7 is started and the password is entered, the desktop file cannot be displayed (the desktop file is roaming on the win2008r2 server). In the lower-right corner of the screen, the Network Disk cannot be accessed. Refresh the desktop file.Analysis:The Network Disk prompts that it cannot be accessed because of two reasons. I. Hardware problems. Here the hardware mainly refers to the network. 2. software problems. There is no third-party softwar
Currently, most layer-3 switch devices in the market support link aggregation and Spanning Tree Protocols, which can effectively improve the overall network performance and meet more user needs. With the gradual development of network applications, telecom-grade switches, especially layer-
The instance explains VLAN division and configuration issues in layer-3 Switch configurations. vlan division and configuration issues cannot be avoided in layer-3 Switch configurations. Generally, there are four categories, how to
VLAN based on a layer-3 switch can resolve conflicting domain, broadcast domain, and bandwidth issues for the LAN. VLAN can be divided based on the network layer. There are two solutions: one is divided by Protocol (if there are multiple protocols in the network; the other is based on the network

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 vswitch gateway configuration method is as follows:
Switch#config tSwitch(config)#interface vlan 1Switch(config-if)#ip address 192.168.1.254 255.255.255.0Switch(config-if)#no shutdownSwitch(config-if)#exitSwitch(config)#
After a L2 Switch is configured with a management IP address, you can use "Telnet 192.168.1.254" to log on to the vswitch within the same network segment of the Managem
routing protocols to generate route tables, and running ARP to parse IP addresses; set the cache IP Forwarding Table item. As a basic network, the IP network is evolving into a multi-service network. Therefore, network devices must provide a data operation platform for different policies. In the smart architecture of the three-tier vswitch in the harbor, each data packet can be processed according to the policy through a fast filter engine.

Virtual router redundancy protocol
Virtual
The proposed router redundancy protocol aims to improve the reliability of the router (layer-3 Ethernet switch) and the external connection by using the backup mechanism. Generally, a default route is set for all hosts in the LAN to specify the def
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

[Background description] The company has an internal DI-604LB + Broadband Router and a layer-3 switch. To prevent broadcast storms in the network, the Administrator has created three VLANs on the layer-3 switch. The company uses D
802.1p network services: Different Levels of gold, silver, and bronze services can be implemented based on different payment options, so as to ensure the services of high-priority users as much as possible. Supports the network layer-3 DiffServ service: it provides packet priority tag and priority differentiation processing.
The above intelligent services can solve the problem of distribution efficiency an
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
