7-2 Filter Configuration
For incoming packets, your Prestige applies data filters only. Packets are processed depending
upon 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, e.g., all the
rules for NetBIOS, into a single set and give it a descriptive name. The Prestige allows you to
configure up to twelve filter sets with six rules in each set, for a total of 72 filter rules in the
system.
You can apply up to four filter sets to a particular port to block multiple types of packets. With
each filter set having up to six rules, you can have a maximum of 24 rules active for a single port.
