+* **apply_implicit_rule** [bool]

+    The True or False value decides if the ACL list will have an Explicit Deny (DENY ANY ANY ANY rule) or an Explicit Allow rule. It is set to False by default, and no Explicit rule is added to the list.
+
+* **implicit_acl_rule** [str]

+* **max_number_acl_rules** [int]
+
+    Sets a limit on how many ACL rules there can be in the ACL list throughout the training session.
