Configuration Fundamentals
The Dell Networking Operating System (OS) command line interface (CLI) is a text-based interface you
can use to configure interfaces and protocols.
The CLI is structured in modes for security and management purposes. Different sets of commands are
available in each mode, and you can limit user access to modes using privilege levels.
In Dell Networking OS, after you enable a command, it is entered into the running configuration file. You
can view the current configuration for the whole system or for a particular CLI mode. To save the current
configuration, copy the running configuration to another location. For more information, refer to Save
the Running-Configuration.
NOTE: You can use the chassis management controller (CMC) out-of-band management interface
to access and manage an Aggregator using the Dell Networking OS command-line reference. For
more information about how to access the CMC to configure an Aggregator, refer to the Dell
Chassis Management Controller (CMC) User’s Guide on the Dell Support website at http://
support.dell.com/support/edocs/systems/pem/en/index.htm.
Accessing the Command Line
Access the command line through a serial console port or a Telnet session (Logging into the System
using Telnet). When the system successfully boots, enter the command line in EXEC mode.

CLI Modes
Different sets of commands are available in each mode.
A command found in one mode cannot be executed from another mode (except for EXEC mode
commands with a preceding do command (refer to the do Command section).
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.
