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

Xcode6 simulator path, xcode6 simulator pathAfter the release of Xcode6, there have been many changes and functional changes. I will not repeat them too much here. On WWDC, Apple has already talked about it and there are many articles on the Internet, here we will introduce some small things that are not easy to find, but very important.1. Xcode6 simulator path c

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

Many readers are not very clear about the formation and working principle of VLAN 《Cisco/H3C Switch configuration and management manualRelated content in the book.8.1.1 understand VLAN formation and working principlesA VLAN is a logical segment of the switching network divided by function, project group, or application policy, regardless of the physical location

. 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-

Tutorial Description: connect to and set the IP address of the PC according to the network topology. PC1 and PC2 are required to be accessed on VLAN 12, while PC3 and PC4 are accessed on VLAN 34, PC1 and PC2 are interconnected, PC3 and PC4 are interconnected, and

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

VLAN division in WLAN The advantage of the access network servicebasic server VLAN extension is that it effectively limits the L2 broadcast domain. For wired networks, common VLAN division methods include switch-based port division, MAC address-based division, L3-Based IP address division, and 802.1x-based security credential division, there are many materials i

Currently, virtualization is widely used. Generally, a physical host can create multiple virtual machines on a physical host after installing VMware ESXi or Hyper-V Virtual Machine Software, in addition, each created virtual machine can provide external services like the original physical machine, which can undoubtedly make full use of server resources to save power and space. But when most of our friends use virtual machines, there is also a problem: the physical host performance is high enough
