Deleting a packet filter set

To delete a packet filter set, select Delete IPX Packet Filter Set in the IPX Filters and Filter Sets screen to display a list of filter sets. Select a filter set from the list and press Return to delete it. Press the Escape key to exit the list without deleting the filter set.

Note: Deleting a filter set does not delete the filters in that set. However, the filters in the deleted set are no longer in effect (unless they are part of another set). The deleted set will no longer appear in the answer profile or any connection profiles to which it was added.

IPX SAP filters

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.

Viewing and modifying SAP filters

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).
