h3c s5024pv3-ei交换机如何查看端口的Discard丢包计数

在H3C S5024PV3-EI交换机上，可通过以下命令查看端口的Discard丢包计数：

1. 使用 `display interface X` 命令查看指定接口的统计信息，重点关注“Discard”字段，显示入/出方向丢包计数。

2. 若需深入分析丢包原因，可执行：
- `display packet-drop interface X`
查看丢包分类统计，包括：
- GBP full或带宽不足导致的丢包
- FFP过滤丢包
- STP非转发状态丢包等

建议结合上述命令综合判断端口是否存在异常丢包或错包。

查看接口的统计信息，没有Discard字段
