## Configure Address Filtering

The Intel® PRO/Wireless 2011B LAN Access Point can keep a list of MAC addresses of the clients not allowed to associate with it. The Disallowed Addresses option prevents unauthorized access by known devices. Use it for preferred association of clients to access points. If no entries have been made for the Access Control List (ACL), the maximum number of entries is 512. This is the total number of entries available to both ACL and Disallowed Address Filtering entries.

### Adding or Removing Disallowed Clients

To add clients to the ACL

1. Select Set Address Filtering from the Main Menu.
2. Select Add -[F2]. The access point prompts for a MAC address.

>      00:00:00:00:00:00

2. Type the MAC address. You can type MAC addresses without colons.

To remove clients from the ACL

1. Use the UP/DOWN-ARROW keys to select the MAC address.
2. Select Delete-[F1] to delete the MAC address.

## Configure Type Filtering

Type filtering prevents the access point from forwarding specific frames, including certain broadcast frames from devices unimportant to the wireless LAN that take up bandwidth. Filtering out unnecessary frames can improve performance. Packet types supported for the type filtering function include the 16-bit DIX Ethernet types. The list can include up to 16 types.

### Adding Filter Types

The Type Filtering screen provides a facility to add types to the list.

1. Select Add-[F2].
2. Enter the packet type.

### Removing Filter Types

The Type Filtering screen provides a facility to remove types from the list.

1. Highlight the packet type using the UP/DOWN-ARROW keys.
2. Select Delete-[F1].

### Controlling Type Filters

Set the type filters to forward or discard the types listed. To control the type filtering mode:

1. Select Set System Configuration from the Main Menu.
2. Select Type Filtering.
3. Press the the spacebar to toggle between the Forward, Discard or Disable type filtering and press ENTER to confirm the choice.
4. To save the Type Filtering Setup information to all access points with the same SSID, select Save ALL APs-[F2]. You can perform this option only among the same hardware platforms and firmware versions. You can only enable one type filtering option at a time.
