To configure the Services Router, including system parameters, routing protocols, interfaces, network management, and user access, you must enter configuration mode. In configuration mode, the CLI provides commands to configure the router, load a text (ASCII) file that contains the router configuration, activate a configuration, and save the configuration to a text file.
You enter configuration mode by entering the configure operational mode command. The CLI prompt changes from user@host> to user@host#.
To view a list of configuration mode commands, type a question mark (?) at the command-line prompt. (You do not need to press Enter after typing the question mark.)

The JUNOS software configuration consists of a hierarchy of statements. There are two types of statements: container statements, which contain other statements, and leaf statements, which do not contain other statements. All the container and leaf statements together form the configuration hierarchy.
Each statement consists of a fixed keyword and, optionally, an identifier that you define, such as the name of an interface or a username.
To configure the Services Router or to modify an existing configuration, you add statements to the configuration with the edit and set configuration mode commands. For more information about the CLI configuration editor and configuration mode, see the J-series Services Router Basic LAN and WAN Access Configuration Guide and the JUNOS software configuration guides.
