Chapter 36 Filter Configuration

2 Go to the Edit Filter Sets field, press [SPACE BAR] to choose Yes and press [ENTER].

This brings you to menu 11.5. Apply the example filter set  (for example, filter set 3) in this 
menu as shown in the next section.

This shows you that you have configured and activated (A = Y) a TCP/IP filter rule (Type = 
IP, Pr = 6) for destination telnet ports (DP = 23).

M = N means an action can be taken immediately. The action is to drop the packet (m = D) if 
the action is matched and to forward the packet immediately (n = F) if the action is not 
matched no matter whether there are more rules to be checked (there aren’t in this example).

Figure 217   Menu 21.1.6.1 Sample Filter Rules Summary

This section shows you where to apply the filter(s) after you design it (them). Sets of factory 
default filter rules have been configured in menu 21 (but have not been applied) to filter 
traffic.
