You will want to configure every switch in an Enterprise network, even though the switches
will forward traffic even with default configuration. This section covers the basic configuration
processes, including the concept of a configuration file and the locations in which
the configuration files can be stored. Although this section focuses on the configuration
process, and not on the configuration commands themselves, you should know all the commands
covered in this chapter for the exams, in addition to the configuration processes.
Configuration mode is another mode for the Cisco CLI, similar to user mode and privileged
mode. User mode lets you issue non-disruptive commands and displays some information.
Privileged mode supports a superset of commands compared to user mode, including commands
that might disrupt switch operations. However, none of the commands in user or
privileged mode changes the switch’s configuration. Configuration mode accepts configuration
commands —commands that tell the switch the details of what to do and how to do it.
Figure 6-7 illustrates the relationships among configuration mode, user EXEC mode, and
privileged EXEC mode .
Figure 6-7 CLI Configuration Mode Versus EXEC Modes
Commands entered in configuration mode update the active configuration file. These
changes to the configuration occur immediately each time you press the Enter key at the
end of a command. Be careful when you enter a configuration command!
