There are three other attributes to each filter:

The filter’s order (i.e., priority) in the filter set

Whether the filter is currently active

When you display a filter set, its filters are displayed as rows in a table:

The table’s columns correspond to each filter’s attributes:

#: The filter’s priority in the set. Filter number 1, with the highest priority, is first in the table.

Source IP Addr: The packet source IP address to match.

Dest IP Addr: The packet destination IP address to match.

Proto: The protocol to match. This can be entered as a number (see the table below) or as TCP or UDP if those
protocols are used.
