Parameters
cmdkey : Specifies the first keyword of a non-undo command or the second keyword of an undo
command. You must enter the keyword in its complete form.
alias : Specifies an alias for the keyword, a string of 1 to 20 characters. It must be different from the
first keyword of any non-undo command and the second keyword of any undo command.
Usage guidelines
You can configure an alias for the first keyword of a non-undo command or the second keyword of an
undo command. Then, when you execute a command that starts with the keyword or the undo
keyword plus the keyword, you can use the alias. For example, if you configure show as the alias for
the display keyword, you can enter show clock to execute the display clock command.
To use configured command keyword aliases, make sure the command-alias enable command is
configured.
Examples
# Define show as the alias of the display keyword.
<Sysname> system-view
[Sysname] command-alias mapping display show
