对不起，如果这是一个菜鸟问题，但我有点迷茫。
我们目前遇到了一些网络问题，在我看来，这些问题似乎很奇怪。最终结果是我有一些备份作业由于网络连接丢失而失败。
我们正在处理的网络是由 6 个 Cisco 3850（运行 IOS-XE 03.06.04.E）组成的堆栈，为我们的整个网络执行 L3 路由。除了执行 L3 路由之外，该堆栈还为该建筑物以及我们的许多服务器托管客户端。
在对备份失败进行故障排除时，我发现了一些奇怪的结果，希望有人能够帮助我。我将一个 20GB 的文件从服务器 A（端口 Gi6/0/44）复制到服务器 B（端口 Gi6/0/38），两者都在同一个 VLAN 上。奇怪的是，发送端口的 rxload 变为 2xx/255（sh cont util 显示 99% 接收）而接收端口的 txload 变为 2xx/255（sh cont util 显示 99% 传输），这似乎完全倒退对我来说。此外，接收端口有很多输出丢失/错误。以下是文件复制期间 2 个接口的 sh int。此外，端口的可靠性在传输过程中似乎有所下降，下降到我见过的 200/255。

我不知道该去哪里或我所看到的要寻找什么。
