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 the Dell Networking OS, after you enter a command, the command is added to 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.

telnet 172.31.1.53

Trying 172.31.1.53...

Connected to 172.31.1.53.

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).
