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 in H3C WX6103 Access Controller Switch Interface Board Command Reference). The
following table lists the operations that you can perform.
Follow these steps to access history commands:

command
Up-arrow key or <Ctrl+P>
Displays the earlier history
command, if there is any.
Access the next history command Down-arrow key or <Ctrl+N>
Displays the next history
command, if there is any.
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.
