The CLI maintains a history of commands that have been entered. You can
scroll back through the history of commands by pressing the up arrow key.
Any command displayed in the history list can be executed again, or first
modified and then executed.
Using the show history command displays a longer list of recently
executed commands.

The command set is divided into Exec and Configuration classes. Exec
commands generally display information on system status or clear
statistical counters. Configuration commands, on the other hand, modify
interface parameters or enable certain switching functions. These classes
are further divided into different modes. Available commands depend on
the selected mode. You can always enter a question mark “ ? ” at the
prompt to display a list of the commands available for the current mode.
The command classes and associated modes are displayed in the following
table:

When you open a new console session on the switch with the user name
and password “guest,” the system enters the Normal Exec command mode
(or guest mode), displaying the “Console>” command prompt. Only a
limited number of the commands are available in this mode. You can
access all commands only from the Privileged Exec command mode (or
administrator mode). To access Privilege Exec mode, open a new console
session with the user name and password “admin.” The system will now
display the “Console#” command prompt. You can also enter Privileged
Exec mode from within Normal Exec mode, by entering the enable
command, followed by the privileged level password “super.”
