## Configure the Access Control List

The Access Control List (ACL) contains MAC addresses for clients allowed to associate with the access point. This provides security by preventing unauthorized access. The ACL supports adding client computer entries by individual MAC address or by a range of MAC addresses. The maximum number of entries is 512 if no entries have been made for Disallowed Address Filtering. Only 512 entries are available to both ACL and Disallowed Address Filtering.

1. Select the Set Access Control List option from the Main Menu to display:

>      Address Type?   range individual

1. Use the UP/DOWN-ARROW keys to toggle between range and individual.

### Setting a Range of Allowed Clients

To select a range of MAC addresses:

1. Type in the minimum MAC address as the top value:

>      00:0A:F8:F0:01:01

2. Press ENTER to accept the value; use the DOWN-ARROW key to select the maximum value.
3. Type in the maximum MAC address in the bottom value:

>      00:0A:F8:F0:02:FF

1. Press ENTER to accept the value. Use the DOWN-ARROW key to select OK.
2. Press ENTER and change the values as needed.
3. To delete a range of wireless clients, select Delete-[F1].
4. To add a range of wireless clients, select Add-[F2].
5. Select Save ALL APs-[F3] to save the Ranges of Allowed Mobile Units information to all access points with the same SSID. This option saves the configuration changes for the current access point, and sends two messages to all other access points on the Known APs table to update their configuration and reset after the configuration has been modified. You can perform this option only among the same hardware platforms and firmware versions.

When you enable the Access Control option, all clients within the specified range can associate with the access point. Specify additional ranges as needed or add to the ACL using individual address entries.
