vxlan vs vlan

Basic knowledge of VLAN division experiment: VLAN is short for Virtual Local Area Network (VLAN), which is a logical Network divided on a physical Network. This network corresponds to the L2 network of the ISO model. VLAN division is not limited by the actual physical location of the network port. A

VLAN is an important part of swap technology. It logically divides a physically directly connected network into multiple subnets. Each VLAN has a corresponding broadcast domain. Different VLANs must communicate with each other through layer-3 switching technology. Layer-3 switching is a technology that combines routing and switching. After the router routes the first data stream, a ing table between the M

The expansion of the enterprise scale has resulted in the continuous expansion of the enterprise's network scale. Many enterprises have adopted the method of directly adding computers to the original network to expand the network scale, the network system becomes more and more complex, and network management becomes more and more difficult. The security indexes in the network become lower and lower, and the utilization of network resources is also greatly reduced, how to effectively manage netwo

There are three port modes: access, hybrid, and trunk. The accesskey can belong to multiple VLANs and receive and send packets from multiple VLANs. It is generally used for connection between switches. hybrid can also belong to multiple VLANs, it can receive and send packets from multiple VLANs. It can be used for connections between switches or between switches and user computers. The main difference between trunk and hybrid is that the hybrid port allows packets from multiple VLANs not to be t

Virtual LAN VLANThe concept of VLANs In the traditional switched Ethernet, all users in the same broadcast domain, when the network size is larger, the number of broadcast packets will increase significantly, when the number of broadcast packets to 30% of the total amount of time, the network transmission efficiency will be significantly reduced, especially when the network equipment failure, and constantly send broadcasts to the network, Which led to broadcast storms. In the actual pro

VLAN (Virtual LAN) technology is an important technical measure to ensure the safe and stable operation of large networks. with the active participation of many vendors and the widespread acceptance of end users, it has been widely used in actual network construction. The reason why VLAN technology is attractive is that it has enhanced its network management functions in three aspects, this simplifies the w

Network environment: A 3550EMI switch, divided into three vlan,vlan2 for the server network, named SERVER,IP address segment is 192.168.2.0, Subnet mask: 255.255.255.0, Gateway: 192.168.2.1, domain Server for Windows Advance Server, concurrently as a DNS server, IP address is 192.168.2.10,vlan3 for client 1 network, IP address segment is 192.168.3.0, Subnet mask: 255.255.255.0, Gateway: 192.168.3.1 named WORK01,VLAN4 for Client 2 network, named Work02

VLAN-based attack methods are used by hackers Based on VLAN technology. How can they take effective preventive measures in the face of these innovative attacks? In this article, we will introduce the hacker's attack methods and the defense measures we can take for the networks managed by the application VLAN technology. Currently, common

MUX VLAN Application ScenarioIn the enterprise network to achieve mutual access between customers and customers, customers and employees are not mutually accessible, employees and employees can access each other, employees and customers can access the server.MUX VLAN is a two-layer traffic isolation mechanismThe MUX VLAN is divided intoPrincipal
