Exploring Command Abbreviations
You can abbreviate commands and keywords by entering the first few characters of a command. The abbreviation must include sufficient characters to make it unique from other commands or keywords. If you are having trouble entering a command, check the system prompt and enter the question mark (?) for a list of available commands. You might be in the wrong command mode or using incorrect syntax.
Example 2-11 illustrates various command abbreviations.

Exploring the no Form of a Command
Almost every configuration command has a “no” form that can be used to disable a feature, revert to a default value, or remove a configuration. Example 2-12 illustrates the no form of the feature command.
