1.2.7 Saving History Commands
The CLI can automatically save the commands that have been used. You can invoke
and repeatedly execute them as needed. By default, the CLI can save up to ten
commands for each user. You can use the history-command max-size command to
set the capacity of the history commands log buffer for the current user interface (For
the detailed description of the history-command max-size command, refer to Login
Commands). The following table lists the operations that you can perform.
Follow these steps to access history commands:

 Note:
You may use arrow keys to access history commands in Windows 200X and XP
Terminal or Telnet. However, the up-arrow and down-arrow keys are invalid in
Windows 9X HyperTerminal, because they are defined in a different way. You can use
<Ctrl+P> and <Ctrl+N> instead.

The commands are executed only if they have no syntax error. Otherwise, error
information is reported.
