Using the CLI 57 Using the CLI This chapter describes how to start using the CLI and describes implemented command editing features to assist in using the CLI. CLI Command Modes Introduction T o assist in configuring devices, the CLI [Co mmand Line Interface] is divided into different command modes.
58 Using the CLI www .dell.com | support.dell.com When starting a session, the initial mode is th e User EXEC mode. Only a limited subset of commands are available in User EXEC Mode. This leve l is r eserved for tasks that do not change the configuration.
Using the CLI 59 The following example illustrates how to access P riv ileged Exec mode and r eturn back to the User EXEC mode: The Exit command is used to return from any mode to the pr evious mode ex cept when returning to User EXEC mode from the P rivileged EXEC mode .
60 Using the CLI www .dell.com | support.dell.com Interface Configuration Mode and Specific Configuration Modes Interface Configuration mode commands are to modify specific interf ace operations. The following are the Interface Configuration modes: • Line Interface —Contains commands to configure the management connections.
Using the CLI 61 1 Start the device and wait until the startup procedure is complete. The User Exec mode is enter ed, and the prompt "Console>" is displayed. 2 Configure the device and enter the necessary commands to complete the r equired tasks.
62 Using the CLI www .dell.com | support.dell.com T erminal Command Buffer Every time a command is entered in the CLI, it is r ecorded on an inter nally managed Command History buffer . Commands stored in the buffer are maintained on a F irst In First Out (FIFO) basis.
Using the CLI 63 Keyboard Shortcuts The CLI has a range of keyboar d shortcuts to assist in editing the CLI commands. The following table describes the CLI shortcuts. CLI Command Conventions When entering commands there ar e certain co mmand entry standards that apply to all commands.
