I first set it, but I don't know why. Today I can only ping one of the two computers on the LAN, So I reset it. Router model: dlink DI-524M (five wireless router) Steps: 1. Reset vro Because the original IP address is forgotten, the factory settings are directly restored. 2. Modify network settings A. Set the router IP address to an intranet IP address in the network. B. Disable DHCP server 3. Connect A vro to a computer as a vswitch At thi

What is a vswitch port? What is the role of the vswitch port? Vswitches cannot play their role in optimizing network performance. After reading this article, you will surely have a lot of GAINS. I hope this article will teach you more. In an Ethernet Switching environment, communication between two workstations is usually not intercepted by a third party. In some cases, we may need such listeners, such as p

Enable vswitch Quick Start attribute knowledge point 1: Quick Start The port of a vswitch is usually connected to many user terminals. On the Cisco CatOS switch, there is a command-set port host to optimize the configuration of the port connected to the terminal. Set port host will disable the channel mode of the port; Set port host activates the spanning tree's fast start (portfast) feature on the port: i

Vswitch basics: Definition of link Aggregation Link aggregation technology (also known as Trunking) or bundling technology Bonding) is essentially a logical data path that combines several physical links between two devices, it is called an aggregation link, as shown in Figure1. The physical links Link1, Link2, and Link3 between vswitches form an aggregation link. The link is logically integrated. The internal composition and data transmission details

Vswitch failure-concept of low Packet Loss Rate Data is divided into data packets for transmission in the network. Each data packet contains information indicating the data and a token that provides data routing. Www.cqpcwx.com, and packet propagation in the general media is a small part of the total because the two final ends are lost after the gap, and most of the data packets will arrive at the destination terminal. The so-called network packet los

Steps for recovering the vswitch Password⒈ Connects the console port of the vswitch to the terminal or the PC simulation terminal. Use a direct connection without Modem to connect the serial port of the PC to the console port of the switch.⒉ First press the mode key on the switch panel, and then turn on the power.⒊ Initialize flash.> Flash_init⒋ Rename the configuration file containing password.> Rename fla

the default undo port hybrid pvid to restore the default port the default value of vlan id is undo port trunk pvid port: note: The default vlan id of the Hybrid port or Trunk port must be consistent with the default vlan id of the connected peer switch, or the port cannot forward packets normally. Note: 1. On an Ethernet switch, the Trunk and Hybrid ports cannot be set at the same time. 2. The Trunk port cannot be configured with the isolate-user-vlan at the same time. The Hybrid port can be co

Analysis on vswitch Policy Routing thoroughly master user requirements. Three frameworks of this article: 1. network topology, 2. Application requirements and implementation analysis; 3. vswitch Policy Routing solution. Under these topics, you will understand a lot of useful knowledge. I. Network Topology The office network is 172 CIDR blocks, and the core switch policy route is 85-1. The NE-1 performs NAT

What if I forget the vro and vswitch password? In some enterprise networks, the passwords of some devices are often forgotten due to human factors. In this case, the administrator needs to recover or change the passwords of these devices one by one, the following configuration example shows how to change the password of these devices. What should we do if the password of a Cisco switch is forgotten and needs to be changed again? First, let's take a l

Vswitch Port SecurityThe most common understanding of port security is to control and manage network traffic based on the MAC address, such as binding a MAC address to a specific port, restrict the number of MAC addresses that a specific port uses, or prohibit the frame traffic of certain MAC addresses from passing through a specific port. Port security means that the network access traffic can be controlled based on 802.1X. First, let's talk about bi
