Rule Operators

When you construct a rule on the Rule Configuration page, Cisco Secure ACS
only allows you to select an operator that is applicable to the type of attribute you
select. For example, if you select the

Cisco:PA:PA-Name

attribute, Cisco Secure

ACS permits the use of the

contains

operator in addition to standard

mathematical operators; however, if you choose the Cisco:PA:OS-Version
attribute, Cisco Secure ACS only permits the use of mathematical operators. For
more information about attribute types, see

NAC Attribute Data Types,
