Learn how to use VLAN networks to become a major contributor. After establishing and configuring enterprise VLAN networks, managing VLAN networks, and maintaining VLAN networks, you will have an in-depth understanding of VLANs. VLAN is a virtual network.

What is the difference between an acl and a vacl between a cisco vlan, its implementation method is to apply the ACL directly to the virtual port of the VLAN, which is the same as the ACL implementation method applied to the physical port. The VLAN access control (VACL), also known as the VLAN access ing table, is impl

A vswitch is not designed as a security device, but is still designed to improve network performance. If you want to add a vswitch to the security mechanism, make sure that you configure the vswitch correctly, second, the switch manufacturer must fully understand and fully implement the basic standards of the switch software. If you have strict requirements on network security and do not use shared switches, you should use dedicated switches to Ensure network security. If a vswitch must be share

Enable VMwareESXi vswitch to support VLAN 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

An analysis of the two-layer VLAN forwarding of Huawei Ethernet switches and its advantages. To solve the problem of VLAN introduced by Huawei Ethernet switches, we must first understand the benefits brought by VLAN introduction. Remember the corresponding instance. Therefore, it is very advantageous to study the following carefully. Packet forwarding thread: Aft

We know that the traditional LAN Ethernet adopts the CSMA/CD method with conflict detection. In the CSMA/CD network, nodes can use the network whenever they have data to be sent. Before a node transmits data, it performs a "listener" to check whether the network is busy. If not, the node starts to transmit data. If the network is in use, the node waits. If the two nodes do not hear anything and start to use the line at the same time, a conflict will occur. When sending data, if it uses a broadca

This paper analyzes the set of VLAN division methods for multiple vswitches. VLAN implementation methods on vswitches can be roughly divided into six categories: VLAN division methods for vswitches Based on port division and VLAN division methods for MAC address vswitches. ◆ VLAN
