Obtaining a Director Appliance Certificate with Internet access

To get a Director appliance certificate for a Director appliance that has access to the Internet:

director # config t
director (config) #
director (config) # ssl request-appliance-certificate
Requesting certificate
Verifying certificate
Certificate verified successfully

NOTE:  This command creates a new private key, creates the Certificate Signing Request (CSR) signature for the private key, and sends the CSR to Blue Coat to get a corresponding appliance certificate.

To display the appliance certificate, please do the following command:

director (config) # show ssl appliance-certificate
