11.8 Configuring TLS Server Certificate Expiry Check
You can also configure the TLS Server Certificate Expiry Check feature, whereby the
device periodically checks the validation date of the installed TLS server certificates. You
can also configure the device to send a notification SNMP trap event
(acCertificateExpiryNotification) at a user-defined number of days before the installed TLS
server certificate is to expire. The trap indicates the TLS Context to which the certificate
belongs.
Note: TLS certificate expiry check is configured globally for all TLS Contexts.
 To configure TLS certificate expiry checks and notification:
1. Open the TLS Contexts page (Configuration tab > System menu > TLS Contexts).
2. Scroll down the page to the TLS Expiry Settings group:
Figure 11-10: TLS Expiry Settings Group
3. In the 'TLS Expiry Check Start' field, enter the number of days before the installed TLS
server certificate is to expire at which time the device sends an SNMP trap event to
notify of this.
4. In the 'TLS Expiry Check Period' field, enter the periodical interval (in days) for
checking the TLS server certificate expiry date. By default, the device checks the
certificate every 7 days.
5. Click the Submit TLS Expiry Settings button.
