CLI command modes provide specific sets of CLI commands. When you log onto the switch, you are in User EXEC mode with limited commands. While in a higher mode, you can access most commands from lower modes, except if they conflict with commands of your current mode.
There are two categories of CLI commands: show commands and configuration commands. You can use show commands from multiple command modes with the same results; they show the same configuration information regardless of the command mode. Configuration command results, however, might be dependent on the command mode from which a configuration command is used. For example, an enable command used in Global Configuration mode will enable a feature globally for all devices, and the same command used from one of the interface command modes will enable a feature for a specific interface only.
The following figure illustrates the navigation paths for the various command modes:
Your user authorization credentials determine what commands are available to you in Privileged EXEC mode and all higher-level modes. See System Access for more information.
To navigate from higher-level modes to lower-level modes, use the following commands:
exit to navigate from a higher-level mode to a lower-level mode, down to Privileged EXEC mode
end to navigate from any command mode directly to Privileged EXEC mode
disable to navigate from Privileged EXEC mode to User EXEC mode
logout to terminate the CLI session from any command mode
The following table describes the various command modes, including the CLI command to access each mode, the command prompt that displays in each mode, and a description of the purpose of the mode.
Note
Some command modes are hardware dependent. If any of the following commands modes do not display on your hardware, they are not supported or applicable.
