Configuration Fundamentals
The Dell Networking 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.
After you enter a command, the command is added to 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.
NOTE: Due to differences in hardware architecture and continued system development, features
may occasionally differ between the platforms. Differences are noted in each CLI description and
related documentation.
Accessing the Command Line
Access the CLI through a serial console port or a Telnet session.
When the system successfully boots, enter the command line in EXEC mode.
NOTE: You must have a password configured on a virtual terminal line before you can Telnet into
the system. Therefore, you must use a console connection when connecting to the system for the
first time.

information about privilege levels and security options, refer to the Privilege Levels Overview section in
the Security chapter.
The CLI is divided into three major mode levels:
