Password:Dell>CLI ModesDifferent sets of commands are available in each mode.A command found in one mode cannot be executed from another mode (except for EXEC mode commandswith a preceding do command (refer to the do Command section).You can set user access rights to commands and command modes using privilege levels.For more information about privilege levels and security options, refer to the Privilege Levels Overview sectionin the Security chapter.The Dell Networking OS 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 alimited selection of commands is available, notably the show commands, which allow you to viewsystem 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 the Configure the Enable Password section in theGetting Started chapter.• CONFIGURATION mode allows you to configure security features, time settings, set logging and SNMPfunctions, configure static ARP and MAC addresses, and set line cards on the system.Beneath CONFIGURATION mode are submodes that apply to interfaces, protocols, and features. Thefollowing example shows the submode command structure. Two sub-CONFIGURATION modes areimportant when configuring the chassis for the first time:• INTERFACE submode is the mode in which you configure Layer 2 and Layer 3 protocols and IP servicesspecific to an interface. An interface can be physical (Management interface, 1 Gigabit Ethernet, or 10Gigabit Ethernet, or synchronous optical network technologies [SONET]) or logical (Loopback, Null, portchannel, or virtual local area network [VLAN]).• LINE submode is the mode in which you to configure the console and virtual terminal lines.Configuration Terminal Batch mode is a special configuration mode that helps in synchronizing theconfigurations across the VLT nodes. This mode is used to setup common configurations on a port extenderconnected in a dual homing environment. You can use the commit command to save the configurationchanges and discard command to cancel the configuration changes.NOTE: At any time, entering a question mark (?) displays the available command options. For example,when you are in CONFIGURATION mode, entering the question mark first lists all available commands,including the possible submodes.The CLI modes are:EXECEXEC PrivilegeCONFIGURATIONAS-PATH ACLCONTROL-PLANECLASS-MAPDCB POLICYConfiguration Fundamentals 40
