28-4 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, e.g., 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.
You can apply up to 4 filter sets to a particular port to block multiple types of packets. Because each filter
set can have up to 6 rules, you can have a maximum of 24 rules active for a single port.
28.2 Filter Set Configuration
To configure a filter set, follow the procedures indicated:
Step 1. Type 21 in the main menu and then enter 1 to configure filter sets.
Figure 28-3 Filter Set Configuration
