Configuring IPX Filter Definitions
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.
