问题描述

尽管设置了更大的TTL值、但DNS更新似乎每30分钟发生一次。

Cluster::> dns dynamic-update show -vserver-fqdn <vserver> Vserver Is-Enabled Use-Secure Vserver FQDN TTL --------------- ---------- ---------- ------------------------ ------- svm_v1 true true svm_v1.domain.net 1d svm_v2 true true svm_v2.domain.net 1d svm_v3 true true svm_v3.domain.net 1d 3 entries were displayed.

MNWd.log：
