NSX Advanced Load Balancer 允许自定义何时触发 SSL 证书过期通知。系统预计最少提供 3 天通知。默认情况下，在过期前 30 天、7 天和 1 天触发警示。

例如，在以下序列中：

  1. 先显示控制器的属性。

  2. 指定两个通知期（45 天和 14 天），并将其保存到配置中。

  3. 显示修订的控制器属性以进行确认。

注：

将自动插入这两个日期并按顺序显示。

要移除任何 warning_days 条目，请在 configure 命令中执行一个序列。例如，

[admin:10-10-26-52]: controllerproperties> no ssl_certificate_expiry_warning_days 14
[admin:10-10-26-52]: controllerproperties> no ssl_certificate_expiry_warning_days 1
[admin:10-10-26-52]: controllerproperties> save
注：

添加所需数量的 warning_days 条目。不过，在移除这些条目时，NSX Advanced Load Balancer 拒绝将条目数减少到低于三个的任何尝试。
