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 largely the same for each platform except for some commands and command outputs. 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 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.

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.

telnet 172.31.1.53

Trying 172.31.1.53...

Connected to 172.31.1.53.

Escape character is '^]'.

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

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 configurations, clear counters, manage configuration files, run diagnostics, and

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