Conguration Fundamentals

The Dell Networking Operating System (OS) command line interface (CLI) is a text-based interface you can use to congure

interfaces and protocols.

The CLI is largely the same for each platform except for some commands and command outputs. The CLI is structured in modes for

security and management purposes. Dierent 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 conguration le. You can view the current

conguration for the whole system or for a particular CLI mode. To save the current conguration, copy the running conguration to

another location.

NOTE: Due to dierences in hardware architecture and continued system development, features may occasionally dier

between the platforms. Dierences 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 congured 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 rst time.

CLI Modes

Dierent 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

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 congurations, clear counters, manage conguration les, run diagnostics, and

enable or disable debug operations. The privilege level is 15, which is unrestricted. You can congure a password for this mode;

refer to the Congure the Enable Password section in the Getting Started chapter.
