The company's network environment is composed of a convincing firewall and Huawei switches S5720 and S2700. As the core equipment and DHCP server, S5700 assigns the IP address to the company's computer, turns on dhcp snooping and detects with arp. As an access device, S2700 detects the authenticity of dhcp request packets. In order to uniformly manage office computers, a domain environment is deployed. At the front end, there was a strange situation in the company's network. Several computers in the department could not get the IP address occasionally when they started up. If they could not go to the IP address, they could not contact the domain controller and could not correspond to the domain policy (the domain controller was equipped with a unified policy for employees' desktops), which caused employees to start up with a black screen. In order to solve this problem, checked the switch configuration, and even called Huawei 400 hotline, no problem. Later, it was found that all the company's network cables were transferred through the connector.

Lead to poor contact, can also access the Internet, is very slow, access to the file server in the local area network is very stuck, and finally decisively connect with the terminal, and then all the troubles are solved.
