In a relatively large network environment, network administrators usually manage and maintain the LAN network workload. How to free up from these trivial and complicated maintenance tasks must be every network management. People are very concerned about things. As a network administrator, are you still running around for LAN workstations?
If there is a network failure in the LAN, are you still using the Ping command to perform connectivity tests on the failed workstations one by one just like when you first contacted the network? Obviously, in a large-scale LAN environment, when relying solely on network administrators to manually manage and maintain the network, the workload is undoubtedly enormous, and the efficiency of network management will not be as high as that; then do you want to A more concise and easy way to manage and maintain your organization's LAN network? In fact, with the help of professional network tools, real-time monitoring of workstation connectivity in LAN networks can make network management and maintenance very easy.
No, NetControl is a good helper next to you. You can add all the workstations and other important network devices in your organization's LAN to an electronic topology diagram. After that, the NetControl tool will monitor the network connectivity status of each workstation in the electronic topology diagram immediately and dynamically. Automatically display the results of dynamic monitoring. You can immediately see from the electronic topology diagram at what point in time the LAN network has a connectivity failure, so that you can quickly and efficiently solve the network failure. .
Setting Instant Monitoring Parameters When using the NetControl tool to monitor the connectivity status of LAN workstations, we naturally have to download the tool from the Internet and install it routinely. After the installation is complete, it is also necessary to properly set its immediate monitoring parameters to ensure that the tool can monitor the occurrence of network failures within the first time. The most important parameter is the setting of the monitoring time interval. If the value is set to a large value at will, the sensitivity of the NetControl tool to monitor the LAN workstation dynamically will not be very high. On the contrary, if the value is set to be relatively small, then NetControl The tools will scan and test the LAN network frequently. This may affect the running performance of the LAN network. When setting the monitoring interval parameter, we can follow the following steps:
First, double-click the NetControl program shortcut icon in the monitoring host to open the main operation interface of the program. Click the “Edit†option in the menu bar of the interface, and click the “Parameter†command from the drop-down menu to open the parameter. Select the Settings window.
The “interval [seconds]†parameter in the setting window refers to the time interval for the NetControl program to scan and test each network device and workstation in the LAN under the dynamic monitoring status. The setting of this parameter often needs to be based on the LAN network. The operating status is set in a targeted manner. This value can neither be set too large nor too small. In general, we can set the value of this parameter to 60 megabytes, which means that every 1 minute is performed on the LAN network. Scan, test once.
The "time activity" parameter refers to the length of the data packet when the NetControl program tests the connectivity status of the network device through the Ping command; the "packet size [byte]" parameter refers to the size of the data packet transmitted in each IP. The "break time" parameter refers to the maximum response time of the network timeout. The unit used for this parameter is milliseconds. Setting this parameter also needs to be different depending on the network operating status. For example, if the parameter is set to be compared When it is large, dynamic monitoring effect may not be achieved. If the value of this parameter is set to be small, the result of dynamic monitoring may be somewhat inaccurate. Normally, the value can be set to 2000-5000.
Monitoring network connectivity status When monitoring workstations or network devices on a LAN network, we also need to draw a complete electronic topology map based on the actual network topology of the LAN network and add these network devices to the electronic topology map. Or the workstation is the object of real-time monitoring of the NetControl program. Therefore, we should add workstations or network devices that are often prone to failure to the electronic topology according to the actual situation of the maintenance network. When adding a workstation or network device to an electronic topology map, we can follow these steps:
First start the NetControl program, click on the "Workstation" function button in the program interface toolbar, then move the mouse pointer to an empty area of ​​the program interface, click the left mouse button, and then the setup window will appear on the screen.
Enter the description of the target workstation in the Display Name text box in the Settings window. In the Address/Name text box, enter the host name or IP address of the target workstation. Afterwards, in the “information†text box, enter the relevant annotation information for the corresponding target workstation, such as the geographical location of the target workstation and the attribute information of the target workstation. With this information, we can often generate a network in the LAN. When a fault occurs, the faulty workstation is quickly found, thereby improving the efficiency of troubleshooting the LAN network.
After confirming that the above information is entered correctly, select the "Monitor" option in the corresponding settings window and click the "OK" button. Then you will see a small computer icon in the NetControl program interface. When the mouse pointer is moved over the icon, the NetControl program will automatically display the previously set workstation parameter information in the status bar, so that we can easily refer to the detailed attribute information of the LAN workstation. It helps us to quickly locate the cause of the fault. If a workstation device is found to be incorrectly added, we can delete it. When deleting a workstation device, we can click on the selection tool in the toolbar of the NetControl program interface, and then click on the workstation icon to be deleted. Click the "Edit"/"Delete" command in the menu bar to delete the currently selected workstation icon from the electronic topology.
According to the same operation method, we can add all workstations and network devices in the LAN of a company to the electronic topology map. After completing the task of adding all the workstations, we then adjust the position of workstations and network devices in the electronic topology map according to the actual placement of LAN workstations and network devices. The method is to use the mouse to directly drag workstations and network device icons. When you are in the right position, release the left mouse button. After adjusting the position of each device in the electronic topology map, we can click the “Line†or “Circle†button in the toolbar of the NetControl program interface to connect each workstation or network device according to the actual networking situation. As a result, we have a complete LAN network topology.
In the future, the NetControl program will periodically send ping packets to each device in the electronic topology diagram according to the monitoring parameters we have set. At the same time, the monitoring test results will be displayed in the electronic topology diagram in time. We only need to check the electronic topology diagram. You can quickly know if there is any connectivity failure on the workstation in the current LAN network. Once a fault is found, we simply move the mouse pointer to the faulty workstation icon, and then the status information automatically pops up based on the NetControl program. Find the fault location and quickly take effective measures to deal with it. As a result, the LAN network management efficiency will be greatly improved.
