This command is not saved in the device configuration; however, the keys generated by this command
are saved in the private configuration which is never displayed to the user or backed up on another
device.
•
RSA keys are saved to the backup master.
•
This command may take a considerable period of time to execute.
Example
The following example generates RSA key pairs.
