ACLs can have a profound effect on the performance of networks. ACL Management
automatically evaluates the effectiveness of rules and their effect on overall network
performance as you add rules to a rule set. You can also manually perform an analysis of a rule
set and optimize its effect on network performance using the Optimize feature. For more
information about using this feature, see " Optimizing the rules in a rule set ."

To delete one or more rules from a rule set, see " Deleting rules from an ACL rule set ."
