Filter Structure
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. The
following diagram illustrates the logic flow when executing a filter rule.
