To allow limited time access to particular secure addresses, set the aging type as absolute. When the aging
time lapses, the secure addresses are deleted.
To allow continuous access to a limited number of secure addresses, set the aging type as inactivity. This
removes the secure address when it become inactive, and other addresses can become secure.
