Login: username Password: FTOS> EXEC mode prompt CLI Modes Different sets of commands are available in each mode. A command found in one mode cannot be executed from another mode (with the exception of EXEC mode commands preceded by the command do; for more information, refer to The do Command and EXEC Privilege Mode commands). You can set user access rights to commands and command modes using privilege levels; for more information on privilege levels and security options, refer to Privilege Levels Overview. The FTOS CLI is divided into three major mode levels: • EXEC mode is the default mode and has a privilege level of 1, which is the most restricted level. Only a limited selection of commands is available, notably show commands, which allow you to view system information. • EXEC Privilege mode has commands to view configurations, clear counters, manage configuration files, run diagnostics, and enable or disable debug operations. The privilege level is 15, which is unrestricted. You can configure a password for this mode; refer to Configuring the Enable Password. • CONFIGURATION mode enables you to configure security features, time settings, set logging and simple network management protocol (SNMP) functions, and static address resolution protocol (ARP) and MAC addresses on the system. Beneath CONFIGURATION mode are sub-modes that apply to interfaces, protocols, and features. The example below shows this sub-mode command structure. When configuring the chassis for the first time, two sub-CONFIGURATION modes are important: • INTERFACE sub-mode is the mode in which you configure Layer 2 and Layer 3 protocols and IP services specific to an interface. An interface can be physical (management interface, 10-Gigabit Ethernet, 40-Gigabit Ethernet, or 2/4/8-Gigabit Fibre Channel) or logical (Loopback, Null, port channel, or VLAN). • LINE sub-mode is the mode in which you to configure the console and virtual terminal lines. Note: At any time, entering a question mark (?) will display the available command options. For example, when you are in CONFIGURATION mode, entering the question mark first will list all available commands, including the possible sub-modes. 32 | Configuration Fundamentals
