number of rules enabled in the policy and the number set to generate events and to drop packets 
and generate events. From this page you can access a read-only view of the Rules page showing

Note that disabled rules are not displayed for the base policy or the Policy Summary. Note also 
that each layer summary provides the total number of rules enabled (that is, the total set to 
generate events or to drop and generate events) in the layer, and the total for each enabled rule 
state. Also, note that the base policy rule state totals are the default enabled rule state settings 
in the policy, and the Policy Summary totals are the effective sum of all enabled rule states for 
all layers in the policy.
