An access control list (ACL) is a list of Access Control Points attached to a Schedule. An ACL specifies which credentials are granted access to access control points and which times are permitted. Each entry in an ACL specifies an Access Control Point and a Schedule.
Step 1: Navigate to Configuration > Access Control Settings > Access Control Lists and Add/Edit a ACL.
Step 2: Define Access Control Rules by associating Access Control Points with Schedules.
