The switch Link light does not stop flashing, but the network speed is still very slow.

The server is slow to access the Internet, and the Ping website cannot resolve the address, but the DNS settings and the server are running normally. Try to ping other computers and find that the packet loss rate is high, and the link indicator of the switch blinks. Even if the switch is turned off and then turned back on, the fault phenomenon is only temporarily relieved, and this fault still occurs afterwards.

Failure analysis

There are many reasons for this failure, such as worms, switch port failures, NIC failures, link redundancy without enabling Spanning Tree Protocol, network line sequence errors, or interference.

Troubleshooting

Viewing the indicator light when a network failure occurs is the most convenient way to judge network connectivity and network traffic. According to the current situation, the worm is the most important cause of network paralysis. Therefore, the server update system patch, install the network version of the virus killing software, even if the virus database is upgraded, the anti-virus client program can be installed on the server to solve the problem.
