Filter Commands
Packet filtering allows each IP packet exiting a router interface to be examined for
a match to a configured set of rules. If all of the conditions in any rule do not
match the contents of the packet, the packet is either forwarded or discarded,
depending upon the filter default for that interface. Otherwise, the exception
action is taken; the packet is discarded or forwarded (the opposite of the default
action). You set the default action for an interface with the
set filter default
command ( page 10-21 ). For more information on packet filter rules, refer to “IP
Packet Filtering” on page 9-12 .
These commands configure packet filter rules.
Table 10-7 lists the filter commands.
