MAC Address Definitions

The Definitions & Users > Network Definitions > MAC Address Definitions tab is the central place for defining MACClosed Media Access Control address definitions, i.e., lists of MAC addresses. A MAC address definition can be used like a network definition. Additionally it can be used to further restrict a rule based on hosts/IP addresses to only match devices which have one of the defined MAC addresses.

Tip – When you click on the Info icon of a MAC address definition, you can see all configuration options in which the definition is used.

To create a MAC address definition, proceed as follows:

  1. On the MAC Address Definitions tab, click New MAC Address List.

    The Add MAC Address List dialog box opens.

  2. Specify the following settings:

    Name: Enter a descriptive name for this definition.

    MAC Addresses: Click the Plus icon to enter individual MAC addresses subsequently or use the Action icon to import a list of MAC addresses via copy and paste. The MAC addresses are usually specified in a format consisting of six groups of two hexadecimal digits, separated by colons or hyphens (e.g., 00:04:76:16:EA:62).

    Note – The MAC address range 00:1a:8c:f0.xx.xx is used by HA/Cluster. You cannot use this range for other purpose as MAC addresses within this range will be overwritten by the system.

    Hosts: Add or select the hosts whose MAC addresses you want to add to the MAC address definition. The MAC addresses defined in the DHCP Settings section of the host definition will be added to the MAC address list. For how to add a network definition, see Definitions & Users > Network Definitions > Network Definitions.

    Note – The number of addresses per address definition is limited for the following uses: To restrict access to a wireless network, it is not recommended to have more than 5000. To restrict access to a RED appliance, you can add a maximum of 200 MAC addresses for RED 10, 300 for RED 15(w), and 400 for RED 20, 50, and 60.

    Note – You can either enter MAC addresses or hosts or both.

    Comment (optional): Add a description or other information.

  3. Click Save.

    The new definition appears on the MAC Address Definition list.

To either edit or delete a MAC address definition, click the corresponding buttons.
