适用于

  • ONTAP
  • Cut-Through 交换机

解答

  • 如果交换机是直通端口、则在 ifstat 上发现的 CRC 错误可能与该端口与相应交换机端口之间的有效通信无关
  • 直通交换机会在完全接收帧之前转发帧、以减少存储和转发帧带来的延迟
  • 交换机会将包含 CRC 错误的帧转发到出站端口、从而导致交换机在完成接收之前开始转发帧
  • 当发生 CRC 错误时、将 LIF 移动到另一个端口将产生将这些数据包重定向到新端口的副作用
  • 这给人的印象是, CRC 错误 " 跟随 " 了新端口的 LIF

其他信息

  • 对 CRC 错误的起源进行故障排除取决于所使用的特定交换机型号和供应商
  • 请与交换机供应商联系以进行进一步调查
