CLI Command Modes
This section describes the CLI command mode structure. Command modes support specific Cisco IOS
commands. For example, the interface type_number command works only when entered in global
configuration mode. These are the main command modes:
• User EXEC
• Privileged EXEC
• Global configuration
• Interface configuration
• Config-vlan
• VLAN configuration
• Line configuration
Table 1-1 lists the command modes, how to access each mode, the prompt you see in that mode, and how
to exit that mode. The prompts listed assume the default name Switch.
