可不使用  

适用于

  • ONTAP 8
  • ONTAP 9

解答

当收到三个无效的 TCP 记录标记之一时,会在 EMS 中记录此错误:

  • tcp_fragment —接收'RPC Last Fragment'到位设置为 0 的数据包

    • ONTAP 不支持这些调用

  • tcp_data_length_overflow —接收到记录标记大于支持的最大值的数据包

    • ONTAP 8.2 之前的 70 KB

    • 集群模式 Data ONTAP 8.2 到集群模式 Data ONTAP 8.3.2-300 KB

    • ONTAP 9 及更高版本– 1 MB

  • tcp_data_length_Underflow —接收到记录标记小于 40 字节的数据包
