vlan segmentation

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

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

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

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

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

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-
