Using the Command-Line Interface 105Understanding Command ModesThe CLI groups commands into modes according to the command function.Each of the command modes supports specific software commands. Thecommands in one mode are not available until you switch to that particularmode, with the exception of the User EXEC mode commands. You canexecute the User EXEC mode commands in the Privileged EXEC mode.To display the commands available in the current mode, enter a questionmark (?) at the command prompt. In each mode, a specific command is usedto navigate from one command mode to another.The main command modes include the following:• User EXEC — Commands in this mode permit connecting to remotedevices, changing terminal settings on a temporary basis, performing basictests, and listing system information.• Privileged EXEC — Commands in this mode permit you to view all switchsettings and to enter the global configuration mode.• Global Configuration — Commands in this mode manage the deviceconfiguration on a global level and apply to system features, rather than toa specific protocol or interface.• Interface Configuration — Commands in this mode configure the settingsfor a specific interface or range of interfaces.• VLAN Configuration — Commands in this mode create and removeVLANs and configure IGMP/MLD Snooping parameters for VLANs.The CLI includes several additional command modes. For more informationabout the CLI command modes, including details about all modes, see theCLI Reference Guide.Table 5-1 describes how to navigate between CLI Command Mode and liststhe prompt that displays in each mode.
