Chapter 39: PKI Certificates and SSL
470 Section IX: Management Security
Guidelines
The guidelines for creating certificates are:
 A certificate can have only one key.
 A switch can use only those certificates that contain a key that was
generated on the switch.
 You can create multiple certificates on a switch, but the device uses
the certificate whose key pair has been designated as the active key
pair for the switch’s web server.
 Most web browsers support both unsecured (plaintext) and secured
(encrypted) operation. These modes are referred to as HTTP and
HTTPS, respectively. If you choose to use encryption when you
manage a switch, the web browser you use must support HTTPS.
