适用于

ONTAP 9

解答

  • ONTAP 支持 31 位子网掩码( /31 )
  • 只能将点对点范围内的第二个 IP 分配给 ONTAP 中的接口
  • 使用 31 位子网掩码传输到 LIF 的 TCP 流量在 ONTAP 9.8 之前不起作用
  • 其他信息

示例

  • 所需的点对点子网为 192.168.1.0/31
  • ONTAP 可以分配到 192.168.1.1
  • 无法为 ONTAP 分配 192.168.1.0
    • 分配将失败 Error: command failed: Netmask and address pair result in a network address
  • ​​​​​​​Below 第一个命令失败,但第二个命令成功,如上所述
 cluster1::> network interface create -vserver svm1 -lif p2p -address 192.168.1.0 -netmask 255.255.255.254 Error: command failed: Netmask and address pair result in a network address cluster1::> network interface create -vserver svm1 -lif p2p -address 192.168.1.1 -netmask 255.255.255.254 cluster::>
