Configuring IPX Filters
Filtering is the method by which the network manager controls usage of a mixed
network by connection-oriented and connectionless traffic. (Connectionless traffic
does not require establishment of a logical connection prior to data exchange.) A filter
permits or denies (depending on how it is configured) some or all of a specific type of
IPX traffic across an interface. For example, a filter can be configured to deny trans-
mission of all outbound IPX SAP entries.
The process of configuring and using IPX filters is as follows. Both procedures are
described later in this chapter.
1. Create an IPX Filter Definition record.
2. Create an IPX Filter Applications record, which will:
◆
Identify the node that contains the interface to be affected.
◆
Identify the interface to be affected (by specifying an ID that matches one in
the IPX Interface file, described later in this chapter).
◆
Specify the filter category: RIP, SAP, packet, or RIP router.
◆
Specify a direction: inbound or outbound.
◆
Specify whether the filter(s) to be applied will permit or deny passage of the
type of data defined by the filter(s).
◆
Identify up to 100 filters to be applied to the interface.
3. Perform an on-line update of the definitions and applications (described under
"Configuring IPX Filter Applications" on page 15-8).
Configuring IPX Filter Definitions
To review existing filter definitions, press
[A]
at the Filter Definitions and Applica-
tions Configuration Menu
(or
[A], [A], [E], [F], [A]
from the Main Menu).
To configure a filter definition, press
[B]
at the Filter Definitions and Applications
Configuration Menu. When prompted, enter:
●
Filter category
:
0
= RIP,
1
= SAP,
2
= Packet,
3
= RIP Router. (The default is
0
.)
●
Filter ID
:
1–65535
. (The default is
1
.) This is simply a unique identifier.
●
Any other requested information, noting the values in Table 15-2 through Table
15-5. (Press
[Enter]
at a prompt to accept a default value.) The display will
depend on the filter category. The following figure shows an example of a SAP
filter record.
