The following table describes command syntax symbols used in this guide.
| Symbol | Description | 
|---|---|
| | | A vertical bar represents an "or" condition, indicating that only one of the parameters in the brackets or parentheses can be selected. | 
| ( ) | Parentheses indicate that one of the parameters must be selected. | 
| [ ] | Brackets indicate optional parameters. | 
| Bold | Commands in bold indicate commands and keywords. | 
| Italic | Commands in italics indicate that you must enter text based on the parameter. | 
In the following examples, location and graceful-shutdown are command names. For the location command, keyword must be one of the keywords cf1, cf2, or cf3. For the graceful-shutdown command, boolean must be one of the keywords true or false, although explicitly using the keyword true is optional.
