Entering and Editing Commands
Notes for entering commands.
• The CLI is not case-sensitive.
• You can enter partial CLI keywords.
•
Enter the minimum number of letters to uniquely identify a command. For example, you cannot enter
cl
as a partial keyword
because both the
clock
and
class-map
commands begin with the letters “cl.” You can enter
clo
, however, as a partial keyword
because only one command begins with those three letters.
• The TAB key auto-completes keywords in commands. Enter the minimum number of letters to uniquely identify a command.
• The UP and DOWN arrow keys display previously entered commands (refer to Command History ).
• The BACKSPACE and DELETE keys erase the previous letter.
• Key combinations are available to move quickly across the command line. The following table describes these short-cut key
combinations.
