1, master several common network commands and use these commands to detect common network faults.

2, understand the meaning of each command, and can explain the meaning of its display content.

Second, the experimental content

1. Run common network commands of windows, such as ipconfig, ping, stat, nbtstat, arp, route and tracert.

2. Use subnet mask to realize subnet division.

3. Understand the various views of vrp and the common commands under each view.

Third, experimental principles, methods and means

By executing some common network commands, this experiment can understand the network situation and better understand some network protocols.

Network command for experiment:?

1, pconfig command

This command displays the specific configuration information of ip protocol. This command can display the physical address of the network card, the ip address of the host, subnet mask and default gateway, and can also view the host name, dns server, node type and other related information.

2.ping command

This command is used to test the network connection status and the information sending and receiving status. This command is used to check the network connection, and it can display the details of the currently active network connection.

3.nbtstat command

This command is used to view the statistics of bios on local computer or remote computer, and display the protocol statistics and bios used in the current tcp/ip connection. With bios, you can view a list of bios names on a local computer or a remote computer.

4.arp command

Using the arp command, you can view the current contents in the arp cache of the local computer or another computer, or you can manually enter the static physical address /ip address pair of the network card, which helps to reduce the amount of information on the network.

Fourth, the experimental steps

1. Execute ipconfig to get the computer network parameters.

2.ping to test the connection with other computers.

3. Execute stat to view the details of the currently active network connection. ?

4. Execute nbtstat to check the statistics of the protocol using nbt and the tcp/ip connection currently using nbt. ?

5. Perform arp to check the ip address and mac address mapping of the current record. ?

6. Execute route to check the routing information of the computer.
