 A one-time password is used to initially create trust between a Gateway and Security Management Server. The administrator generates a one-time password from SmartConsole and enters it on the gateway command line interface using the cpconfig command. This establishes a Secure Internal Communication (SIC) between the gateway and the server . The other options are not used for this purpose.
