Viewing certificate information
By default, the system generates a unique SSL certificate for each controller. For the strongest security, you can replace the
default system-generated certificate with a certificate issued from a trusted certificate authority.
The Certificate Information panel shows information for the active SSL certificates that are stored on the system for each
controller. Tabs A and B contain unformatted certificate text for each of the corresponding controllers. The panel also shows
one of the following status values as well as the creation date for each certificate:
● Customer-supplied. Indicates that the controller is using a certificate that you have uploaded.
● System-generated. Indicates that the controller is using an active certificate and key that were created by the controller.
● Unknown status. Indicates that the controller's certificate cannot be read. This most often occurs when a controller is
restarting, the certificate replacement process is still in process, or you have selected the tab for a partner controller in a
single-controller system.
You can use your own certificates by uploading them through FTP or SFTP or by using the contents parameter of the
create certificate CLI command to create certificates with your own unique certificate content. For a new certificate to
take effect, you must first restart the controller for it. For information on how to restart a controller, see Restarting or shutting
down controllers.
To verify that the certificate replacement was successful and the controller is using the certificate that you have supplied, make
sure the certificate status is customer-supplied, the creation date is correct, and the certificate content is the expected
text.
