[Technical Support Department] Technical Team A (Fan Liu): network maintenance task partially completed

Task Work Report

On the evening of January 30, 403, the local area network of the nut Lab Building was maintained.

I will describe my work in the following parts:

1. According to the fault they described, I checked the IP addresses of several computers and found that many computer ip addresses were conflicted.

2. based on IP address conflicts, shut down the previous computer, leave only a few computers to open it, manually set the IP address, set it, and Ping each other, but the ping still fails, only a few of them can be pinged. We guess there is a problem with the vswitch. However, when I was going to further confirm whether there was a problem with the switch, Mr. Zhong, who is in charge of technical management in the computer department laboratory, was passing by. Mr. Zhong proposed to help solve the problem, so I paused my work and watched the study. Mr. Zhong used the software provided by Lenovo to control various computers. Mr. Zhong first randomly operated on several computers. Other computers did not respond. Then, he checked the switch and said that there was a problem with the switch (which is the same as my previous idea). He suggested that we use one of them to control other computers, then, huide operated on one of the computers, and finally fixed the network localization between nearly 15 computers in the laboratory.

 

Conclusion: From my point of view, I think most of the problems have been solved, but some of them have not been solved because of the time relationship (too late) between the teacher and me, so I have only fixed 10 servers. This is because I want to handle all my computers. Therefore, this task is not complete, but I already know how to solve this problem. I will be fully prepared next time.
