Keyword Source or destination
Up-arrow key
Ctrl+P
Recalls commands in the history buffer, beginning with the most recent command.
Repeats the key sequence to recall successively older commands.
Down-arrow
key
Returns to more recent commands in the history buffer after recalling commands with
the up-arrow key. Repeating the key sequence will recall successively more recent
commands.
By default, the history buffer system is enabled, but it can be disabled at any time. For information about
the command syntax to enable or disable the history buffer, see history.
There is a standard default number of commands that are stored in the buffer. The standard number of
10 commands can be increased to 256. By configuring 0, the effect is the same as disabling the history
buffer system. For information about the command syntax for configuring the command history buffer,
see history size.
To display the history buffer, see show history.
Negating the Effect of Commands
For many configuration commands, the prefix keyword no can entered to cancel the effect of a
command or reset the configuration to the default value. This guide describes the negation effect for
all applicable commands.
Command Completion
If a command is entered and it is not complete, if the command is invalid, or if some parameters of the
command are invalid or missing, the appropriate error message is displayed. This assists in entering
the correct command. By pressing the <Tab> button, an incomplete command is entered. If the
characters already entered are not enough for the system to identify a single matching command,
press "?" to display the available commands matching the characters already entered.
Incorrect or incomplete commands are automatically re-entered next to the cursor. If a parameter must
be added, the parameter can be added to the basic command already displayed next to the cursor. The
following example indicated that the command interface ethernet requires the parameter <port-num>.
(config) # interface ethernet
%missing mandatory parameter
(config) # interface ethernet e5
