In filtering, packets are analyzed against a set of rules. Only those which satisfy
these conditions and have a “
permit
” flag attached are allowed through the filters
and sent to the requesting system. The permit traffic can also be logged. The rest
are discarded and can optionally be logged.
E
XAMPLE
The example below sets a permit rule on all IP traffic across the filter.
ALU(config)# ip filter f1
ALU(config-filter-f1)# 10 match m1 permit log
The example below configures a deny rule with reset option on all the IP traffic on
the filter configured.
ALU(config-filter-f1)# 10 match m1 deny reset
