Conventions Used in Command Descriptions
The following conventions are used for command descriptions:
•Examples containing system prompts denote interactive sessions. Such examples
indicate that you should enter commands at the system prompt.
The system prompt indicates the current level of the EXEC command interpreter. For
example, the prompt router> indicates that you are at the user EXEC level; the prompt
router# indicates that you are at the privileged EXEC level.
Access to the privileged EXEC level requires a password. Refer to the section entitled
“If You Need More Configuration Information” in Chapter4 for additional information.
•Commands and keywords are in boldface font.
•Arguments for which you supply values are in italic font.
•Elements enclosed in square brackets ([ ]) are optional.
•Alternative, but required, keywords are grouped in braces ({ }) and separated b y vertical
bars (|).
•The symbol ^ represents the key labeled Control. For example, the key combin ation ^Z
means that you should hold down the Control key while pressing the Zkey.
