• You must enter the minimum number of letters to uniquely identify a command. For example, cl
cannot be entered as a partial keyword because both the clock and class-map commands begin with
the letters “cl.”
clo, however, can be entered as a partial keyword because only one command
begins with those three letters.
• The TAB key auto-completes keywords in commands. You must enter the minimum number of letters
to uniquely identify a command.
• The UP and DOWN arrow keys display previously entered commands (see Command History).
• The BACKSPACE and DELETE keys erase the previous letter.
• Key combinations are available to move quickly across the command line, as described in Table 2-2.
Command History
FTOS maintains a history of previously-entered commands for each mode. For example:
• When you are in EXEC mode, the UP and DOWN arrow keys display the previously-entered EXEC
mode commands.
• When you are in CONFIGURATION mode, the UP or DOWN arrows keys recall the
previously-entered CONFIGURATION mode commands.
