Vswitches are still commonly used, so I have studied common troubleshooting methods for vswitches. Here I will share with you some of them, hoping they will be useful to you. Vswitch faults are diverse, and different faults have different manifestations. In the case of fault analysis, you must use various phenomena to flexibly use troubleshooting methods, such as exclusion, comparison, and replacement metho

In daily network fault maintenance, the most commonly used equipment is the switch, especially the access layer switch, which serves as a bridge connecting users and switching routing devices. The switch acts as an intermediate, it plays a very important role in troubleshooting network faults. If we have an understanding of its own faults, we may be able to help us quickly and more accurately identify and solve problems, we will share with you the

Because of the length, not a post all finished, but also not so fast all translated, so according to the chapter published. Due to my limited level, translation results must be problematic, in order not to mislead, at the end of each attached to the original text for

From: http://www.pcdog.com The cause of an error on the IIS server is complex. Errors such as service startup failure, IIS process interruption, or site failure will be recorded in system logs. No matter what errors occur in IIS, you should use the Event Viewer to view related events recorded in system logs before determining the troubleshooting solution. Some errors are apparently caused by hardware damage to the server, while others are often imperc

Network diagnosis is an important technical task that manages and makes good use of the network to maximize its role. This article briefly describes the hierarchical diagnosis technology, discusses the diagnosis of various router interfaces, and reviews the troubleshooting of the connectivity fault of the interconnected network. Network Fault Diagnosis Overview Network Fault Diagnosis: based on the fault phenomenon, the Network diagnosis tool is used

We all know that each computer needs an address to access the Internet normally. This address is what we often call an IP address. How can we effectively manage these IP addresses as network administrators? You can set the corresponding IP address, subnet mask, gateway address, DNS address, and other network parameters for each computer, but it is very cumbersome and heavy workload, conflicts often occur in practical applications. How can we effectively allocate these network parameters? The DHC

Faults are inevitable during network management and O M. If an administrator attempts to build a zero-fault network, it will be futile. There are too many randomness and contingency factors in network faults, not to mention human factors. Therefore, what administrators need to do is to master the network troubleshooting skills, accumulate experience to cultivate a keen sense of smell, and be able to quickly locate and eliminate faults without detours

In the daily use of switches, There will be various problems. The first problem is that the environment is wet, the circuit board is damp and short-circuited, or the components are due to high temperature and other problems, the following article describes the classification and troubleshooting of switch faults. Common switch fault categories: Several smart solutions are provided. The following describes switch fault categories and common fault soluti

The instance explains network cable faults during ADSL fault handling. The configuration of ADSL Fault Handling mainly describes the similarities and differences between the network cable fault and the indicator lights of ADSL. The configuration can be completed easily, there is no difficulty. Hurry into the Wireless World. Instance 1: network cable failure Fault description: multiple computers share the Internet with the ADSL Fault Handling Modem through the Hub. Check the local connection. The

switch is moved, or when the power supply is unstable.Of course, the three modules mentioned above have external interfaces, which are easy to identify. Some modules can also identify faults through the indicators on the module. For example, a stacked module has a flat trapezoid port, or some switches have interfaces similar to USB. The management module has a Console port for establishing a connection with the network management computer to facilitate management. If the expansion module is con

Switch troubleshooting: a layer of equipment is used to help the detector. You are very interested in troubleshooting the switch. Before giving you a detailed description of how to troubleshoot a vswitch, let's first take a look at a layer of equipment, such as a hub, to help the monitor collect the required information. Since the vswitch is a layer-2 device, it cannot forward all information traffic. So le

It is very useful to know some troubleshooting methods for access networks, and it also gives us more convenience in actual use. So I have studied the specific implementation methods of access network troubleshooting, And I will share with you here, hoping it will be useful to you. As a comprehensive technology, network fault diagnosis involves many aspects of network technology. Before learning the concept
