Cisco Access Control List (how to isolate vlan, acl, and vacl)

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

TCP/UDP communication between PC computer and Android simulator access and simulator

The Android system defaults to only a one-way access to the PC via IP (10.0.2.2), and PC computers cannot access the Android emulator system directly via IP. A port redirection (redir) is required to enable communication between PC and Android emulator systems and the Android emulator. First, the Telnet client installation required for Port redirection: Windows: Install the Telnet client. If it is not installed, you can enable Telnet client functionality by locating the Telnet clien

How can VLAN be prevented from causing disasters?

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

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

Introduction and benefits of VLAN L2 forwarding of Huawei Ethernet switches (1)

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

How to configure VLAN Division on a vswitch

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

Analysis of VLAN division methods for multiple switches

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

Detailed explanation of VLAN Technology and its practical application in Enterprises

There are many things worth learning about VLAN technology. Here we mainly introduce VLAN Technology and its practical application in enterprises. VLAN Virtual LAN (VLAN) refers to the logical segmentation of network users connected to the second layer switch port, and segment networks according to user requirements wi

VLAN settings for large enterprise networks

When a large number of subordinate organizations interconnect isolated networks, VLAN division is required for the management, security, and stable operation of the entire network for different functional departments.At the time of the rise of Enterprise Networks, due to the small scale of Enterprise Networks, limitations in application scope, lack of understanding of Internet access, and poor network security and management, so that the enterprise ne

Are you still worried about simulators for android Developers? God-level android simulator --- Genymotion, a faster and nearly perfect simulator ......

Abstract: The Android system is very special. The App needs to undergo simulated testing. Even so, there is still a solution-virtualization technology. Previous simulators, such as those provided by eclipse, were very slow, and the Simulator version was not the latest. Boot can be said to almost force you into a desperate situation, slow to death; load a program, wait for you to come back after the toilet to find that the load is not complete, no matt

Use a layer-3 Switch to implement VLAN management for large and medium-sized enterprises

The expansion of VLAN enterprises in large and medium-sized enterprises with layer-3 switches has led to the continuous expansion of enterprise networks, many enterprises use the method of adding computers directly to the original network to expand the network scale. As a result, the network system becomes increasingly complex and network management becomes increasingly difficult, the security index in the network is also getting lower and lower, and
