Configuration FundamentalsThe Dell Networking Operating System (OS) command line interface (CLI) is a text-based interface you can use to configure interfaces andprotocols.The CLI is largely the same for each platform except for some commands and command outputs. The CLI is structured in modes forsecurity and management purposes. Different sets of commands are available in each mode, and you can limit user access to modes usingprivilege levels.In the Dell Networking OS, after you enter a command, the command is added to the running configuration file. You can view the currentconfiguration for the whole system or for a particular CLI mode. To save the current configuration, copy the running configuration toanother location.NOTE: Due to differences in hardware architecture and continued system development, features may occasionally differ betweenthe platforms. Differences are noted in each CLI description and related documentation.Topics:• Accessing the Command Line• CLI Modes• The do Command• Undoing Commands• Obtaining Help• Entering and Editing Commands• Command History• Filtering show Command Outputs• Multiple Users in Configuration ModeAccessing the Command LineAccess 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.
