Chapter 6: Definition Reference
In policy files, definitions serve to bind a set of conditions, actions, or transformations to a
user-defined label.
Two types of definitions exist:
• Named definitions—Explicitly referenced by policy.
• Anonymous definitions—Apply to all policy evaluation and are not referenced directly in rules.
There are two types of anonymous definitions: DNS and RDNS restrictions.
Definition Names
There are various types of named definitions. Each of these definitions is given a user-defined name
that is then used in rules to refer to the definitions. The user-defined labels used with definitions are
not case-sensitive. Characters in labels may include the following:
•letters
•numbers
•space
•period
• underscore
•hyphen
•forward slash
•ampersand
The first character of the name must be a letter or underscore. If spaces are included, the name must be
a quoted string.
Only alphanumeric, underscore, and dash characters can be used in the name given to a defined
action.
The remainder of this chapter lists the definitions and their accepted values. It also provides tips as to
where each definition can be used and examples of how to use them.
