To Configure a Rule for a Filter:
[<1-65535>] match [any|all] <match-list name>...
{permit|deny [reset]}[log] [verbose] [timer <timer-object>]
The above command is used to configure rules (set priority for the rule, associate
match-lists and action) for a filter, and also set the action deny or permit for the
configured rules.
default {deny|permit}[log] [verbose]
This command sets a default action of either deny or permit on the filter. The
default action for a filter is “deny”. The reset keyword can be used in conjunction
only with the “deny” keyword.
The example below sets a permit rule so that only traffic defined by m1 is
permitted.
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 traffic as defined in
m1.
ALU(config-filter-f1)# 10 match m1 deny reset
Parameter Description
1-65535 Denotes the filter rule number. The
range for the filter rule.
match [any|all] <match-list
name>
match all - In this type of match, the
relevant action is performed only when
all the match-list criteria is satisfied.
match any - In this type of match, the
relevant action is performed even if any
one of the match-list criterion is satisfied.
deny This command prohibits the traffic

deny[reset] Keyword "deny reset" sends TCP RST to

other non-TCP traffic.
