Conguration Fundamentals

The Dell Networking OS command line interface (CLI) is a text-based interface that you use to congure interfaces and protocols.

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.

For more information, refer to Saving the Running-Conguration.

Accessing the Command Line

Access the command line through a serial console port or a Telnet session as shown in the following example.

When the system successfully boots, you enter the command line in EXEC mode (shown in bold).

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.

Logging into the System using Telnet

telnet 172.31.1.53

Trying 172.31.1.53...

Connected to 172.31.1.53.

Escape character is '^]'.

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 preceded by the do command;

for more information, refer to

The do Command and EXEC Privilege Mode commands).
