我有以下问题。我在一个房间的 17 台计算机上安装了 Arch Linux，所有计算机都连接到一台 Cisco 交换机。 （英特尔 NUC5PPY，配备 120GB SSD 和 4GB RAM）。

当我启动一台计算机时，登录并 ping 8.8.8.8 通常工作正常，但当我打开更多计算机时，问题就开始了 - ping 开始出现巨大的数据包丢失。每台计算机都位于 1000Mb/s 以太网上，通过电缆 (CAT5) 连接。
没有记录（网络）错误，dmesg 中没有断开连接。
ping 标准输出结束：
64 bytes from 8.8.8.8: icmp_seq=874 ttl=59 time=5.10 ms
64 bytes from 8.8.8.8: icmp_seq=875 ttl=59 time=6.15 ms

当我将任何其他计算机（例如我的 ThinkPad X240）连接到任何交换机端口时，互联网工作没有问题，没有数据包丢失。
