COMMAND LINE INTERFACE
interfaces and status are keywords, ethernet is an argument that specifies the interface type, and 1/5 specifies the unit/port.
You can enter commands as follows:
•To enter a simple command, enter the command keyword.
•To enter multiple commands, enter each command in the required order. For example, to enable Privileged Exec command mode, and display the startup configuration, enter:
Console>enable
Console#show
•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 0 smith
Minimum Abbreviation
The CLI will accept a minimum number of characters that uniquely identify a command. For example, the command “configure” can be entered as con. If an entry is ambiguous, the system will prompt for further input.
Command Completion
If you terminate input with a Tab key, the CLI will print the remaining characters of a partial keyword up to the point of ambiguity. In the “configure” example, typing con followed by a tab will result in printing the command up to “configure.”
Getting Help on Commands
You can display a brief description of the help system by entering the help command. You can also display command syntax by using the “?” character to list keywords or parameters.
