适用场景

  • ONTAP 9
  • NFS
  • MTU (最大传输单元)
  • MSS (最大区块大小)
  • IP碎片

问题解答

  • 不会、 只要较大的MTU (9000)发送的数据不 会超过较小的MTU (1500)、就不会出现IP碎片
    • NFS客户端是唯一发起TCP连接(三次握手)的端、MSS将限制NAS端的帧大小、因此不会产生IP碎片

追加信息

  • 可以通过查看(查找关键字fragments"")来检查NAS (ONTAP)端的IP碎片
    • autosupport: NETSTAT_S.TXT
    • ::> system node run -node * -command "netstat -s -p ip"
