Configuration Fundamentals

The Dell Networking OS command line interface (CLI) is a text-based interface that you use to configure

interfaces and protocols.

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 enable a command, it is entered into 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. For more information, refer to

Saving the Running-Configuration.

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 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.

Logging into the System using Telnet

telnet 172.31.1.53

Trying 172.31.1.53...

Connected to 172.31.1.53.
