entered in place of a parameter. The matched parameters for this
command are displayed.
The following features and conventions are applicable to CLI command entry
and editing:
• History Buffer
• Negating Commands
• Show Command
• Command Completion

History Buffer
Every time a command is entered in the CLI, it is recorded in an internally
managed Command History buffer. Commands are stored in the buffer,
which operates on a
First In First Out (FIFO)
basis. These commands can be
recalled, reviewed, modified, and reissued. This buffer is not preserved after
switch resets.
By default, the history buffer system is enabled, but it can be disabled at any
time. The standard number of 10 stored commands can be increased to 216.
By configuring 0, the effect is the same as disabling the history buffer system.
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
<Ctrl>+<N>
Returns to more recent commands in the history buffer after
recalling commands with the up-arrow key. Repeating the key
sequence recalls more recent commands in succession.
