An integer that determines the precedence order of this ACL in the list of ACLs applied to interfaces of the specified role combination. An ACL with a given precedence order is positioned in the list before one with a higher-valued precedence order.

As an example, consider the following ACL Target association:

Index IfRoleCombo IfDirection AclId AclType Order 14 'eth1000+L2+L3' 'in' 8 '802' 1 15 'eth1000+L2+L3' 'in' 3 '802' 2 16 'eth1000+L2+L3' 'in' 12 'IP' 3 17 'eth1000+L2+L3' 'in' 6 'IP' 4 18 'eth1000+L2+L3' 'in' 21 'IP' 5

Five distinct ACL specifications, 3 from an IP ACL Definition class and 2 from an IEEE 802 ACL Definition class, form an Acl Target association (e.g., based on the specified interface role combination and direction attributes) with a prescribed order of evaluation. The AclType and AclId attributes identify the ACL Definition instances in their respective classes.

Precedence values within an association must be unique otherwise instance installation will be prohibited and an error value will be returned.
