回答

のソース none は、エントリが負のキャッシュエントリであることを示します。

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

追加情報

ONTAP が特定のネットグループのメンバーではないホスト名に IP が解決すると判断すると、負のキャッシュエントリが入力されます。
