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 section in 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 a limited selection of commands is available, notably the 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 the Configure the Enable Password section in the Getting Started chapter. • CONFIGURATION mode allows you to configure security features, time settings, set logging and SNMP functions, 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. The following example shows the submode command structure. Two sub-CONFIGURATION modes are important 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 services specific to an interface. An interface can be physical (Management interface, 1 Gigabit Ethernet, 10 Gigabit Ethernet, 25 Gigabit Ethernet, 40 Gigabit Ethernet, 50 Gigabit Ethernet, or 100 Gigabit Ethernet) or logical (Loopback, Null, port channel, or virtual local area network [VLAN]). • LINE submode is the mode in which you to configure the console and virtual terminal lines. 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: EXEC EXEC Privilege CONFIGURATION AS-PATH ACL CONTROL-PLANE CLASS-MAP DCB POLICY DHCP DHCP POOL ECMP-GROUP EXTENDED COMMUNITY FRRP INTERFACE GROUP GIGABIT ETHERNET 10 GIGABIT ETHERNET 40 GIGABIT ETHERNET INTERFACE RANGE LOOPBACK MANAGEMENT ETHERNET NULL PORT-CHANNEL TUNNEL VLAN VRRP IP IPv6 IP COMMUNITY-LIST IP ACCESS-LIST STANDARD ACCESS-LIST EXTENDED ACCESS-LIST MAC ACCESS-LIST LINE AUXILLIARY CONSOLE VIRTUAL TERMINAL LLDP LLDP MANAGEMENT INTERFACE MONITOR SESSION MULTIPLE SPANNING TREE 36 Configuration Fundamentals
