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 startup-config
• 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 config. 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
“logging console” example, typing log followed by a tab will result in
printing the command up to “logging.”
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.
