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

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

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

Technical standards for VLANs IEEE 802.1Q was formally promulgated by IEEE Commissioners in June 1999, and the earliest Vlna technology was proposed by Cisco (Cisco) companies in 1996. With the development of the past few years, VLAN technology has been widely used in large and small enterprise networks, becoming the most popular Ethernet LAN technology at present. This article is going to introduce one of the most common switch technology application

on the vswitch through the Trunk link; after receiving the frame, the switch removes the VLAN2 tag and sends it to the computer on vlan2. this enables communication between VLANs. Disadvantages of single-arm routing: The communication between VLANs must be completed by routers. As the data volume increases, the channel between the vro and vswitch will become the bottleneck of the entire network: Single-arm route diagram Commands used in single-arm routing configuration: Create Sub-interface Int

The expansion of enterprise scale has created the continuous expansion of enterprise network scale, many enterprises in the expansion of the network scale used in the original network directly to increase the computer method to achieve, followed by the network system has become more and more complex, the network management has become increasingly difficult, the network security index has become increasingly low, and the utilization rate of network resources is greatly reduced, how to manage the

The rapid development of the current exchange technology has also accelerated the application speed of the VLAN-Virtual Local Area Network (VLAN-Virtual Local Area Network) technology, especially on the current campus Network. By dividing campus networks into virtual subnets (VLANs), network management and network security can be enhanced to control unnecessary data broadcasts. Data broadcasting plays a ver

. Instead of using a vro to define subnets of any size, it is better to use a vswitch to create a Virtual Local Area Network (VLAN ).VLAN management VLAN is inseparable from the switch network, but the management environment must be redefined for implementing VLAN. The VLAN-
