wiring methods called twist connection.Different devices are connected using a flat connection. The same device is connected using a twisted connection.The computer, router, and hub and switch are connected using a flat line.This is because there are four lines in the network cable, one is input and the other is output. The input should correspond to the output.If you connect 1 and 3, and 2 and 4, the output is sent to your input.In this way, the NIC can enter the working status, and the interf

5. desktop switchesA table-based switch is the most common low-end switch. It is different from other switches in that it supports a small number of MAC addresses per port. Generally, the number of ports is smaller than 12, but it is not absolute), only has the most basic switch features, of course, the price is also the cheapest.Although this type of switch is the lowest in the entire switch, it still has the general superiority of the switch compared with the hub. Besides, many application env

What is a vswitch fiber port? What is the optical fiber port of a vswitch? What is the difference between a fiber-optic port of a vswitch and a common port? After reading this article, you will know a lot and hope you can learn more. Cascade uses both common ports and special MDI-II ports. A straight-through cable should be used when the two ports that are cascad

Vro and vswitch A computer network is often composed of many different types of network connections. If several computer networks are physically connected together and cannot communicate with each other, then this "interconnection" is meaningless. Therefore, when talking about "interconnection", it is suggested that these computers can communicate with each other. That is to say, in terms of functions and logic, these computer networks have formed a

Physical connections must be established between two hosts. physical connections include network cables, optical fiber cables, and wifi and Bluetooth. These methods are collectively ref

Vro functions: Many people have used vrouters, but have not used vswitches. They do not sound the same, but their functions are similar. Let's get to know about the vswitch today. What are the specific scenarios of its use? What are the vro functions of a vswitch? What is the difference? First, the HUB, that is, the HUB. Its function can be simply understood as connecting some machines to form a LAN. A

Both the vswitch and the vro must have a certain degree of security. That is to say, they must be configured with a reasonable password in a timely manner. What should we do if this password is forgotten? I have met this time. Due to job transfer, the former network administrator left the department, but set a password on the switch, and did not tell me the network administrator who took over. What should we do? Sending it back to the vendor for crack

The backboard bandwidth of A vswitch is the maximum amount of data that can be transferred between the vswitch interface processor or interface card and the data bus. The backboard bandwidth indicates the total data exchange capability of a vswitch. The unit is Gbps. It is also called the switching bandwidth. The bandwidth of A

How to configure a vswitch (1) Today, as a "Dummies" switch is born, how to configure the switch is a profound learning for many people. When asked how to configure the switch, some people will ask: do I still need to configure the vswitch? Indeed, the vswitch configuration process is complex and varies with the brand and product. How should we configure the

security measures are always passive. No enterprise's security system can be truly guaranteed by 100%. Research and Analysis of the virus principle and the Development of intrusion defense technology show that a single anti-virus software often makes network security inadequate, network security cannot be achieved by a single device or technology. Under the recently widely-promoted security policies such as "soft and hardware integration" and "internal and external correspondence", vswitches, a

Before using a vswitch, it is necessary to set the security of the vswitch. Here we mainly introduce some common methods and precautions for the security of the vswitch. How does one filter user communication to ensure secure and effective data forwarding? How can we block illegal users and protect network security applications? How can we conduct security networ

Although the current vswitches do not require initial configuration, they can work normally after being directly connected to the network. However, we may face a situation where, without the initial configuration of the switch, its subsequent troubleshooting and maintenance will become a disaster. If you do not plan the name of a vswitch properly, it will be difficult to match the name of the vswitch with t

PC2 is connected to port E0/2 of vswitch, IP address 2.2.2.2/243. e0/24 indicates the uplink port of the vswitch. 4. the Server is connected to port E0/8 of the

distance is enough for a small network in the same building! Use Uplink switch port Cascade Now, more and more switches except Cisco switches) provide Uplink ports to simplify the connection between switches. Uplink port is a port dedicated for connecting to other vswitches. You can use a straight-through jumper to connect this port to any port other than the Uplink port of other vswitches, the connection method is the same as that between the computer and the switch. Note that some brands of v

Ethernet packet exchange, but with a certain degree of ability to process IP layer or even higher layer data packets. Optical Switching Light exchange is the next generation exchange technology that people are developing. Currently, all switching technologies are based on electrical signals. Even the current optical fiber switch converts optical signals into electrical signals. After switching, the optical signals are sent back to another optical fiber. Because the photoelectric conversion rate

The SNMP protocol is often used for device management and monitoring in LAN Management, and the weakness of SNMP has become the key to our penetration. Only one community string is required to use the SNMP management device. The so-called password usually uses the default public/private password or weak password, and it is easier to crack the SNMP password or guess the dictionary. This allows us to scan and manage vswitches. First, we need to set up an intranet server as a stepping stone. By obs

In the recent work to run the Ubuntu16 instance in Windows Server 2016/hyper-v 10, you need to create a "plug and Play" image file, which is installed to ssh in from outside. Before I used Hyper-V, I was accustomed to using external vswitch as an interface for external communication of virtual machines in the network dynamic assignment IP mode. The virtual machine in this mode is equivalent to a new host in the LAN, and it is very convenient to obtain

There are many things worth learning about vswitch ports. Here we mainly introduce the process of accelerating vswitch port initialization. It may take 30 seconds or more to connect a computer to a vswitch before the computer can communicate over the network. If you are waiting for a long time, 30 seconds of waiting will make you feel very long. Let's take a look

Two vswitch configuration modes: Configure VLAN Based on port division as an example. Vswitch configuration modes can be divided into two categories: one is the configuration mode represented by a CISCO switch, and the other is the configuration mode represented by a Huawei or H3C switch. In fact, the two configuration modes are not essentially different, but the command names and configuration methods are
