Configuring IPX 15-3
Configuring IP X 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 e xchange.) A filter
permits or denies (depending on how it is configu red) 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 d efined 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
Config urat i on Menu. When pr ompted , ent er :
●Filter category: 0 = RIP, 1 = SAP, 2 = Packet,
3 = RIP Route r. (The defaul t is 0.)
●Filter ID: 1–65535. (The defaul t is 1.) This is simply a unique identifier.
●Any other requested information, noting the values in Tab le 15 -2 th rough Tab le
15-5. (Press [Enter] at a prompt to accept a default value.) The display will
depend on the filter category. The followin g figure shows an e xample of a SAP
filt er reco rd.
