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
Table 1-3.

history-command command

z Because the Windows 9x HyperTerminal explains the up and down arrow keys in a different way,
the two keys are invalid when you access history commands in a Windows 9x HyperTerminal
environment. However, you can use Ctrl+P and Ctrl+N instead to achieve the same purpose.
z When you enter the same command multiple times consecutively, only one history command entry
is created by the command line interface.
