Editing Features
Entering Commands
A CLI command is a series of keywords and arguments. Keywords identify a command, and
arguments specify configuration parameters. For example, in the command show interfaces status
ethernet 1/e11, show, interfaces and status are keywords, ethernet is an argument that specifies
the interface type, and 1/e11 specifies the port.
To enter commands that require parameters, enter the required parameters after the command
keyword. For example, to set a password for the administrator, enter:
Console(config)# username admin password alansmith
When working with the CLI, the command options are not displayed. The command is not selected
from a menu, but is manually entered. To see what commands are available in each mode or within
an interface configuration, the CLI provides a method of displaying the available commands, the
command syntax requirements and in some instances, parameters required to complete the
command. The standard command to request help is the character ?.
There are two instances where help information can be displayed:
• Keyword lookup — The character ? is entered in place of a command. A list of all valid
commands and corresponding help messages are is displayed.
•
Partial keyword lookup — If a command is incomplete and or the character ? is entered in
place of a parameter. The matched keyword or parameters for this command are displayed.
