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:

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 and instead.
