Avi Load Balancer enables you to customize when SSL certificate expiry notification is triggered. The system expects a minimum of three notification days. By default, the alerts are triggered 30 days, seven days, and one day before expiry.
For instance, in the below sequence:
The Controller's properties are first displayed.
Two notification periods (45 days and 14 days) are specified and saved into the configuration.
The revised Controller properties are displayed as confirmation.
Note:
The two dates are automatically inserted and displayed in sequence.

To remove any of the warning_days entries, execute a sequence within the configure command. For instance,
[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
Note:
Add as many warning_days entries as required. However, when removing them, Avi Load Balancer will reject any attempt to reduce the number of entries below three.
