DESCRIPTION
This bar displays the percentage of the NWA's PKI storage space that is currently in use.
When the storage space is almost full, you should consider deleting expired or
unnecessary certificates before adding more certificates.
Double-click an entry or select it and click Edit to open a screen with an in-depth list of
information about the certificate.
The NWA keeps all of your certificates unless you specifically delete them. Uploading a
new firmware or default configuration file does not delete your certificates. To remove an
entry, select it and click Remove. The NWA confirms you want to remove it before doing
so. Subsequent certificates move up by one when you take this action.
You cannot delete certificates that any of the NWA's features are configured to use. Select
an entry and click Object Reference to open a screen that shows which settings use the
entry.
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.
This field displays the date that the certificate expires. The text displays in red and
includes an Expired! message if the certificate has expired.
Click Import to open a screen where you can save the certificate of a certification
authority that you trust, from your computer to the NWA.
