Chapter 32 Filter Configuration The following tables contain a brief description of the abbreviations used in the previous menus. The protocol dependent filter rules abbreviation are listed as follows: Table 127 Rule Abbreviations Used ABBREVIATION DESCRIPTION IP Pr Protocol SA Source Address SP Source Port number DA Destination Address DP Destination Port number GEN Off Offset Len Length Refer to the next section for information on configuring the filter rules. 32.2.1 Configuring a Filter Rule To configure a filter rule, type its number in Menu 21.1.1 - Filter Rules Summary and press [ENTER] to open menu 21.1.1.1 for the rule. To speed up filtering, all rules in a filter set must be of the same class, that is, protocol filters or generic filters. The class of a filter set is determined by the first rule that you create. When applying the filter sets to a port, separate menu fields are provided for protocol and device filter sets. If you include a protocol filter set in a device filter field or vice versa, the P-792H v2 will warn you and will not allow you to save. 32.2.2 Configuring a TCP/IP Filter Rule This section shows you how to configure a TCP/IP filter rule. TCP/IP rules allow you to base the rule on the fields in the IP and the upper layer protocol, for example, UDP and TCP headers. 344 P-792H v2 User's Guide
