administrators of small and medium-sized enterprises to have the opportunity to manually configure a switch. The detailed configuration process of a vswitch is complex, and the specific configuration method varies depending on different brands and vswitches of different generations. therefore, we cannot be familiar with all the vswitch configuration and management methods. We only need to understand the general configuration methods. With these gener

loop monitoring function of the Ethernet 16 port, in the system view of the switch, enter the string command "interfaceGigabitEthernet1/0/16" and click the Enter key. After the switch is configured, the view status of port 16 on the Ethernet is displayed, at the same time, the command line prompt of the switch will automatically become "

The switch carries data packets and completes transmission tasks. It is at the data link layer of the network, establishes data links between nodes, and provides data packets transmitted without errors through error control. After a vswitch is installed, the network administrator generally does not care about it. If a problem occurs, the network administrator only checks whether the light is shining. To learn more about the configurations of A vswitch

Today, the company broke the switch, called the engine room replaced on standby, backup switch management IP, was accidentally cleaned by colleagues, can not be remote, wipe.Call the machine room to connect the console port to the server and install the mimicom#apt-get Install minicomConfiguration:#minicom-SPop-up menu-select "Serial Port Setup" to enter level two menu, the first uppercase character of each

The core switch is still quite common. So I studied how to use the DHCP relay of the core switch to increase security performance. I would like to share it with you here and hope it will be useful to you. In a LAN environment, network virus attacks are always inevitable. Once a workstation is accidentally infected with a network virus, it cannot access the Internet normally. In addition, if you change the I

results, the failure assumption caused by the number of connections setting is excluded. The IBMX3600 server is newly purchased, so it is suspected that the fault is caused by a conflict between the new device and the installed examination system. So I immediately moved to another backup server, IBMX236, which can be used normally in another laboratory. However, when I switched to the backup server, the fault remained. So far, it is preliminarily determined that the fault has nothing to do with

In the LAN working environment, encounter network virus attack is always unavoidable things, once the workstation accidentally infected with the network virus, then it can not be normal access to the Internet; In addition, users to change the IP address at will, the local area network is prone to the phenomenon of IP address conflict, once such a failure occurs, Workstations will also not be able to access the Internet properly. In order to control the Internet access stability, this article sta

Two-layer switch: Two-layer switching technology is a mature development, two-layer switch is a data link layer device, can identify the MAC address information in the packet, according to the MAC address forwarding, and the MAC address and the corresponding port record in their own internal address table. Specifically as follows: (1) When the switch receives a

Two-tier switch:The second layer switching technology is more mature, two layer switch is a data link layer device, can identify the MAC address information in the packet, according to the MAC address to forward, and these MAC addresses and corresponding ports recorded in their own internal table of addresses. Specific as follows:(1) When the switch receives a packet from a port, it reads the source MAC add

What is a fool switch? It is easy to understand the introduction is not to take care of its switch, connected to the network equipment can be used. With the development of modern society, the modern "lazy person" also more and more, those who light, convenient, easy and labor-saving "lazy people" is more and more modern "lazy people" welcome. Today's switches are increasingly "goofy", such as the Omni-qs-5

The configuration mode of the switch can be broadly divided into two categories: one is the configuration mode represented by the Cisco switch, and the other is the configuration mode represented by Huawei and the H3C switch. In fact, the two configuration modes are not fundamentally different, but the configuration of

This article introduces the knowledge of switch stack and the principle of switch stack. There are many problems with switch stack on the network. For vswitches of various models, a q A topic about switch stack is provided below. I hope to give all questions about switch st

IntroductionTraditional routers have isolated networks, isolated broadcasts, routing and forwarding, and firewall operations in the network, and as the network continues to evolve, the load of routers is growing rapidly. One of the important reasons is that the VLAN (virtual local area network) technology is widely used in networks because of security and management convenience. VLAN technology can logically isolate different network segments, ports, or even hosts, and the communication between

Switch-case retrun break, switch-caseretrun { If statements process two branches, the if-else-if structure must be used when processing multiple branches. However, if there are many branches, the more nested if statement layers, the program is not only huge but also difficult to understand. therefore, the C language provides a condition selection statement specifically used to process multi-branch structur

" communication between Host A and Host C is actually carried out indirectly through the Host where the hacker is located, that is, Host B acts as the "intermediary, information can be stolen and tampered. This attack method is called Man-In-The-Middle attack ". IP/MAC spoofing attacks Common spoofing types include MAC spoofing, IP spoofing, and IP/MAC spoofing. Hackers can forge the source address of a message to attack the attacker. Generally, the objective is to forge an identity or obtain pr
