Usage Guidelines
The history feature provides a record of commands you have entered. This feature is particularly useful
for recalling long or complex commands or entries for the purposes of modifying them slightly and
reissuing them.
The terminal history size command enables the command history feature and sets the command history
buffer size. The terminal no history size command resets the buffer size to the default of 10 command
lines.
Table 6
lists the keys and functions you can use to recall commands from the history buffer. When you
use these keys, the commands recalled will be from EXEC mode if you are in EXEC mode, or from all
configuration modes if you are in any configuration mode.
