怎么看交换机接口是否存在错误包

您好，请知：

可以使用dis int gi 1/0/1类似的命令查看

[H3C]dis int gi 1/0/1

端口入方向报文计数错误字段解释
 input errors：各种输入错误的总数。
runts：表示接收到的超小帧个数。超小帧即接收到的报文小于 64 字节，且包括有效的 CRC 字段，报文格式正确。
 giants：是超过端口设置的 Maximum Frame Length 的报文个数。
 CRC：表示接收到的 CRC 校验错误报文个数。
frame：端口接收时出错的报文。
端口出方向报文计数错误字段解释
 output errors：各种输出错误的总数。
aborts：表示发送失败的报文总数。
 deferred：表示延迟报文的总数。报文延迟是指因延迟过长的周期而导致发送失败的报文，而这些报文由于发送媒质繁忙而等待了超过 2 倍的最大报文发送时间。
collisions：表示冲突帧总数，即在发送过程中发生冲突的报文。
 late collisions：表示延迟冲突帧，即发送过程中发生延迟冲突超过 512bit 时间的帧。
