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.
In Dell Networking OS, after a command is enabled, 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.

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.

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).
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
