DESCRIPTION
This field displays what kind of certificate this is.
REQ represents a certification request and is not yet a valid certificate. Send a
certification request to a certification authority, which then issues a certificate. Use
the My Certificate Import screen to import the certificate and replace the request.
SELF represents a self-signed certificate.
*SELF represents the default self-signed certificate, which the ZyAIR uses to sign
imported trusted remote host certificates.
CERT represents a certificate issued by a certification authority.
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.

2. Select the radio button of another self-signed certificate and click Details (see
the description on the Create button if you need to create a self-signed certificate).
3. Select the Default self-signed certificate which signs the imported remote
host certificates check box.
4. Click Apply to save the changes and return to the My Certificates screen.
5. The certificate that originally showed *SELF displays SELF and you can delete
it now.
Subsequent certificates move up by one when you take this action.
