For example, let’s say the first inspector’s orders are to send along 
all packages that come from Rome, and the second inspector’s 
orders are to reject all packages that come from France. If a 
package arrives from Rome, the first inspector sends it along 
without allowing the second inspector to see it. A package from 
Paris is ignored by the first inspector, rejected by the second 
inspector, and never seen by the others. A package from London is 
ignored by the first two inspectors, and so it’s seen by the third 
inspector.

In the same way, filter sets apply their filters in a par ticular order. 
The first filter applied can pass or discard a packet before that 
packet ever reaches any of the other filters. If the first filter can 
neither pass nor discard the packet (because it cannot match any 
criteria), the second filter has a chance to pass or reject it, and so 
on. Because of this hierarchical structure, each filter is said to have 
a priority. The first filter has the highest priority, and the last filter 
has the lowest priority.

You use filter sets by linking them to par ticular connection profiles 
and the answer profile. When you create a connection profile or edit 
the answer profile, you can specify a filter set for that profile to use.
