Note: If the Set Name field is left blank, the entire set will be 
deleted.

Note: The Type, Local and Global Start/End IPs are configured 
in menu 15.1.1.1 (described later) and the values are displayed

Ordering your rules is important because the ZyAIR applies the rules in the order that you 
specify. When a rule matches the current packet, the ZyAIR takes the corresponding action 
and the remaining rules are ignored. If there are any empty rules before your new configured 
rule, your configured rule will be pushed up by that number of empty rules. For example, if 
you have already configured rules 1 to 6 in your current set and now you configure rule 
number 9. In the set summary screen, the new rule will be rule 7, not 9. 

Now if you delete rule 4, rules 5 to 7 will be pushed up by 1 rule, so as old rule 5 becomes rule 
4, old rule 6 becomes rule 5 and old rule 7 becomes rule 6.

Set Name

Enter a name for this set of rules. This is a required field. If this field is left blank, the 

entire set will be deleted.

Action

The default is Edit. Edit means you want to edit a selected rule (see following field). 

Insert Before means to insert a rule before the rule selected. The rules after the 

selected rule will then be moved down by one rule. Delete means to delete the 

selected rule and then all the rules after the selected one will be advanced one rule. 

None disables the Select Rule item.

Select Rule

When you choose Edit, Insert Before or Delete in the previous field the cursor jumps 

to this field to allow you to select the rule to apply the action in question.
