Note You can issue EXEC-level Cisco IOS commands (such as show, clear, and debug commands) from within global configuration mode or other modes by issuing the do command followed by the EXEC command. See the do command for information on how to use this command.

Using the No and Default Forms of Commands

Almost every configuration command has a no form. In general, enter the no form to disable a function. Use the command without the keyword no to reenable a disabled function or to enable a function that is disabled by default. For example, IP routing is enabled by default. To disable IP routing, specify the no ip routing command and specify the ip routing command to reenable it. This publication provides the complete syntax for the configuration commands and describes what the no form of a command does.

Configuration commands can have a default form. The default form of a command returns the command setting to its default. Most commands are disabled by default, so the default form is the same as the no form. However, some commands are enabled by default and have variables set to certain default values. In these cases, the default form of the command enables the command and sets variables to their default values. This publication describes what the default form of a command does if the command is not the same as the no form.
