Filter Configuration 
For incoming packets, your Prestige applies data filters only. Packets are processed depending on whether a 
match is found. The following sections describe how to configure filter sets. 
 
The Filter Structure of the Prestige 
A filter set consists of one or more filter rules. Usually, you would group related rules, for example, all the 
rules for NetBIOS, into a single set and give it a descriptive name. You can configure up to twelve filter 
sets with six rules in each set, for a total of 72 filter rules in the system.
