适用场景

ONTAP 9.3 及更高版本

问题解答

none 表示此条目为负缓存条目:

cdot95::> set advanced; vserver services name-service cache netgroups ip-to-netgroup show -vserver test

Warning: These advanced commands are potentially dangerous; use them only when directed to do so by NetApp personnel.
Do you want to continue? {y|n}: yes

Vserver   IP Address  Netgroup    Source  Create Time
---------- ----------- ------------ ------- -----------
test     10.1.2.3   foobar     none   7/1/2021 11:02:19

追加信息

如果 ONTAP 确定某个 IP 解析为非特定网络组成员的主机名,则会输入负缓存条目。
