For information on the syntax for building traffic profile conditions and host profile qualifications, see:

Adding and Linking Conditions

You can create simple traffic profile conditions and host profile qualifications, or you can create more 
elaborate constructs by combining and nesting conditions.
When your construct includes more than one condition, you must link them with an 
AND
 or an 
OR
 
operator. Conditions on the same level are evaluated together:
  •
The 
AND
 operator requires that all conditions on the level it controls must be met.
  •
The 
OR
 operator requires that at least one of the conditions on the level it controls must be met.
For example, the following traffic profile contains two conditions linked by 
AND
. This means that the 
traffic profile collects connection data only if both conditions are true. In this example, it collects HTTP 
connections for all hosts with IP addresses in the 10.4.x.x subnet.
In contrast, the following traffic profile, which collects connection data for HTTP activity in either the 
10.4.x.x network or the 192.168.x.x network, has three conditions, with the last constituting a complex 
condition.
