software commands are in a text-based interface that allows you to use the launch commands, change command modes, and
configure interfaces and protocols.
Topics:
• Accessing the Command Line
• Multiple Configuration Users
• Obtaining Help
• Navigating the CLI
• Using the no Command
• Filtering show Commands
• Enabling Software Features on Devices Using a Command Option
• Command Modes
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 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.
Example
telnet 172.31.1.53
Trying 172.31.1.53...
Connected to 172.31.1.53.
Escape character is '^]'.
Login: username
Password: DellEMC>
After you log in to the switch, the prompt provides you with the current command-level information. For example:

CLI Command Mode
DellEMC>
EXEC
DellEMC#
EXEC Privilege

CONFIGURATION
NOTE: For a list of all the command mode prompts, refer to the Command Modes section.

operating software generates an alert warning message similar to the following:
