LABEL DESCRIPTION
PKI Storage
Space in Use
This bar displays the percentage of the ZyWALL’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.
Add Click this to go to the screen where you can have the ZyWALL generate a certificate or a
certification request.
Edit Double-click an entry or select it and click Edit to open a screen with an in-depth list of
information about the certificate.
Remove The ZyWALL 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 ZyWALL confirms you want to remove it before
doing so. Subsequent certificates move up by one when you take this action.
Object References You cannot delete certificates that any of the ZyWALL’s features are configured to use.
Select an entry and click Object References to open a screen that shows which settings
use the entry. See Section 7.3.2 on page 122 for an example.
