부적절한 구성: 워크 스테이션을 스위치의 여러 포트에 연결 한 후, 로컬 지역 네트워크의 다른 컴퓨터를 핑할 수 없습니다., 하지만 “로컬 연결” 데스크탑의 아이콘은 여전히 ​​네트워크 연결을 보여줍니다.

해결책: Check whether these pinged computers are installed with a firewall first. The three-layer switch can set the VLAN (virtual local area network). Workstations in different VLANs cannot be pinged without setting the route, so it is necessary to modify the VLAN settings so that they are in a VLAN, or set the route so that VLANs can communicate with each other. This kind of fault is sometimes difficult to detect and requires a certain amount of experience. Before configuring, it is best to read the manual. If you can’t ensure that there is a problem with the user’s configuration, please restore the factory default configuration first, and then configure it step by step.
