Command History

The CLI provides the command history function. You can use the display history-command command
to view a specific number of latest executed commands and execute them again in a convenient way.
By default, the CLI can store up to 10 latest executed commands for each user. You can view the
command history by performing the operations listed in the following table:
Follow these steps to view history commands:
Purpose
Display the latest executed
history commands
Recall the previous history
command
Recall the next history
command
The Windows 9x HyperTerminal explains the up and down arrow keys in a different way, and
therefore the two keys are invalid when you access history commands in such an environment.
However, you can use <Ctrl+ P> and <Ctrl+ N> instead to achieve the same purpose.
When you enter the same command multiple times consecutively, only one history command entry
is created by the command line interface.
