Conguration Fundamentals

The Dell Networking OS command line interface (CLI) is a text-based interface you can 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.

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.

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

Accessing the Command Line

Access the CLI through a serial console port or remote 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.
