A MAC address is a 48-bit number typically written in hexadecimal notation that provides a unique address for each client device. An OUI is the first 24 bits of a MAC address. After a MAC object is assigned to a device, it can be grouped to a specific hive. In a MAC firewall policy rule, you can determine which traffic to permit or deny based on the source or destination MAC address. For more information about firewall policies, see Add MAC Firewall Policies. In QoS traffic classification and marking policies, you can prioritize traffic based on its OUI.
Use this task to configure a MAC object and MAC OUI.
