DESCRIPTION
This bar displays the percentage of the ZyXEL Device's PKI storage space that is
currently in use. The bar turns from green to red when the maximum is being
approached. When the bar is red, you should consider deleting expired or
unnecessary certificates before adding more certificates.
This field displays the certificate index number. The certificates are listed in
alphabetical order.
This field displays the name used to identify this certificate.
This field displays identifying information about the certificate's owner, such as CN
(Common Name), OU (Organizational Unit or department), O (Organization or
company) and C (Country). It is recommended that each certificate have unique
subject information.
This field displays identifying information about the certificate's issuing certification
authority, such as a common name, organizational unit or department,
organization or company and country. With self-signed certificates, this is the
same information as in the Subject field.
This field displays the date that the certificate becomes applicable. The text
displays in red and includes a Not Yet Valid! message if the certificate has not yet
become applicable.
This field displays the date that the certificate expires. The text displays in red and
includes an Expiring! or Expired! message if the certificate is about to expire or
has already expired.
This field displays Yes if the certification authority issues Certificate Revocation
Lists for the certificates that it has issued and you have selected the Issues
certificate revocation lists (CRL) check box in the certificate's details screen to
have the ZyXEL Device check the CRL before trusting any certificates issued by
the certification authority. Otherwise the field displays "No".
Click the details icon to open a screen with an in-depth list of information about the
certificate.
Click the delete icon to remove the certificate. A window displays asking you to
confirm that you want to delete the certificates. Note that subsequent certificates
move up by one when you take this action.
