In the next example, you add 

Var1

 with the value 192.168.1.0/24 to Custom Set 1 as in the previous 

example, but you elect not to use the configured value of 

Var1

 as the default value in other sets.

This approach adds 

Var1

 to all sets with a default value of 

any

. After adding 

Var1, 

you can customize 

its value in any set. An advantage of this approach is that, by not initially customizing 

Var1

 in the default 

set, you decrease your risk of customizing the value in the default set and thus inadvertently changing 
the current value in a set such as Custom Set 2 where you have not customized 

Var1

.

Protection

When you select 

 on the Object Manager page (

), the object 

manager lists the default variable set and any custom sets you created. 

On a freshly installed system, the default variable set is comprised only of the default variables 
predefined by Cisco.

Each variable set includes the default variables provided by Cisco and all custom variables you have 
added from any variable set. Note that you can edit the default set, but you cannot rename or delete the 
default set.

Importing an access control or an intrusion policy overwrites existing default variables in the default 
variable set with the imported default variables. If your existing default variable set contains a custom 
variable not present in the imported default variable set, the unique variable is preserved. For more 
information, see 

The following table summarizes the actions you can take to manage your variable sets.
