适用场景

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

问题解答

  • 不可以,只要较大的 MTU ( 9000 )不发送大于较小的 MTU ( 1500 )的任何内容,就不会存在 IP 碎片
    • NFS 客户端是唯一启动 TCP 连接(三向握手)的端, MSS 将限制 NAS 端帧的大小,因此不会产生 IP 碎片

追加信息

  • 可以查看(查找关键字 "fragments" )来检查 NAS ( ONTAP )端的 IP 碎片

    • ::> system node run -node * -command "netstat -s -p ip"
