to cancel the effect of a command or reset the configuration to the default
value. For example, the logging command will log system messages to a
host server. To disable logging, specify the no logging command. This

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.
command classes and associated modes are displayed in the following table:
