Organizing Rules in a Policy
License: 
Any
The Edit page for the access control policy lists access control rules in numerical order. The numeric 
position of each rule appears on the left side of the page next to the rule. You can move or insert rules 
and otherwise change the rule order. For example, if you move rule 10 under rule 3, rule 10 becomes rule 
4 and all subsequent numbers increment accordingly.
A rule’s position is important because the system compares packets to rules in the numeric order in 
which the rules are arranged on the policy Edit page. When a packet meets all the conditions of a rule, 
the system applies the conditions of that rule to the packet and ignores all subsequent rules for that 
packet.
Optionally, you can specify a rule’s numeric position when you add or edit a rule. You can also highlight 
a rule before adding a new rule to predetermine the default position of the new rule to be below the rule 
you highlighted. See 
.
To locate specific rules, you can use partial or complete strings to search for rules by rule name or by a 
name or value in configured rule conditions. You can also filter rules to display only rules for selected 
devices targeted by your policy.
You can select one or more rules by clicking a blank space in the row for the rule. You can drag and drop 
selected rules into a new location, thereby changing the position of the rules you moved and all 
subsequent rules. You can cut or copy selected rules and paste them above or below an existing rule. You 
can delete selected rules and insert new rules into any location in the list of existing rules.
You can further organize rules by adding custom categories between the administrative and root 
categories. You can delete or rename custom categories that you add.
You can display explanatory warnings to identify rules that will never match because they are preempted 
by preceding rules.
The following table summarizes the actions you can take to organize your rules.
