CRL Expiration Warnings

When CRL checking is enabled, if a CRL expires, users might be locked out of the NNMi console. To help avoid unwanted lockouts, NNMi provides health warning messages to alert administrators that a CRL has either expired or will be expiring soon.

The expired CRL warning (Major severity) occurs when one or more CRLs have expired.

The expiring CRL warning (Minor severity) occurs when one or more CRLs has less than 1/6th of its valid period remaining. For example, if a CRL is valid for 24 hours, NNMi displays a warning if the CRL expires in fewer than four hours.

Configure the refresh period such that CRLs are always kept fresh. A properly configured refresh period ensures that, if the CRL server is unavailable for a time, there is a sufficient valid period remaining for the downloaded CRLs. In this way, NNMi can continue normal operation until the CRL server is available. In this example, a refresh period of eight hours might be appropriate.
