Understanding Command Modes
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:
Exec Commands
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.
