information about predefined-filter settings, see “Working with predefined call
filters” on page 6-21.)
Note:
For information about IPX SAP filters, pertaining to NetWare services
the Pipeline adds to its service table, see Chapter 4, “Configuring IPX Routing.”
Overview of Filter profiles
You apply a filter to an interface by specifying its profile number. The Pipeline
applies all filter conditions defined in a Filter profile to the Connection or Answer
profile where it is specified.
Figure 6-3 shows how filters are organized in the menu interface, and the
terminology used to describe each part of a filter.
Figure 6-3. Filter organization and terminology
The menus shown in Figure 6-3 are nested, beginning with the Filters menu. That
is, the numbered Filter profile menus are found under the Filters menu; the Input
or Output filter menus are found under each numbered Filter profile menu, and so
forth. Each level of the Filters menu is described as follows:
• Filters menu
The Filters menu contains a list of numbered profiles. When applying a filter,
you identify it by the unique portion of its Filter profile number, for example,
you would use 1, 2, or 3, rather than 20-401, 20-402, or 20-403.
• Filter profile
A Filter profile is a set of filter conditions.
