Users Guide

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, or 10 Gigabit Ethernet, or synchronous
optical network technologies [SONET]) 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.
Configuration Terminal Batch mode is a special configuration mode that helps in synchronizing the configurations across the
VLT nodes. This mode is used to setup common configurations on a port extender connected in a dual homing environment.
You can use the commit command to save the configuration changes 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.
