Configuring IPX Filters

IPX Filter Configuration Definitions
Configuring IPX
Filtering is the method by which the network manager controls usage of a mixed
network by connection-oriented and connection-less traffic. (Connection-less 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.
Filters are configured at the network level so they will be available for use on all IPX
interfaces without the need to reconfigure them at each interface. Application of these
filters is configured separately for each interface.
The process of configuring and using IPX filters is as follows:
1. Create a filter (see IPX Filter Configuration Definitions below)
2. Create an IPX Filter Applications record (described on
