For each IPX SAP filter, you can configure a set of parameters to 
match on certain attributes of IPX SAP packet entries. The filters 
check IPX SAP packets for entries that match and then act on those 
entries. The SAP packets themselves are always allowed to 
continue after their entries are checked.

The purpose of filtering SAP packets is not to make your network 
more secure, but to add efficiency to network bandwidth use. 
Filtering SAP packets may reduce the size of SAP packets and SAP 
bindery tables by removing unwanted entries.

To display a table of IPX SAP filters, select Show/Change IPX SAP 
Filters in the IPX Filters and Filter Sets screen. 

To modify any of the filters in the table, select the desired filter and 
press Return to go to the Change SAP Filter screen. The parameters 
in this screen are the same as the ones in the Add SAP Filter screen 
(see the next section).

To add a new IPX SAP filter, select Add IPX SAP Filter in the IPX 
Filters and Filter Sets screen and press Return to go to the Add SAP 
Filter screen.
