You can restrict the show output by specifying an interface
name, which will show only rules for that interface, or by
specifying a filter name, which will show only that filter.
Showing all rules is the default. However, please observe that
the automatically generated rule which drops all non-matching
packets is NOT shown in the display. Use the more option to
page through the output, with Ctrl-C to exit.
Delete existing packet filter rules with
del pktfilter:
# del pktfilter -name <filterName> -interface <interfaceName> -all
CAUTION: For-
tress advises users
to be aware that the
packet inspection
required in order to fil-
ter packets in this way is
CPU-intensive and thus
may cause decreased
throughput or increased
latency of packets.
You can restrict which filters to delete by specifying an interface
name, which will delete only rules for that interface, or by
specifying a filter name, which will delete only that filter. The
user must enter one of the three choices (
-name, -interface,
or
-all).
The automatically generated deny rule cannot be deleted. It is
important to remember that if you delete all filters from a given
interface but you leave packet filters enabled on that interface,
all IP packets in or out of that interface will be dropped.
