through the use of MAC address list. The MAC Address Filtering settings apply for
all traffic except Intra-VLAN and Intra-SSID.

STEP 2 Click On to enable the MAC Address Filtering feature, or click Off to disable it.
STEP 3 If you enable MAC Address Filtering, choose one of the following options as the
MAC Address Filtering policy:
•Block MAC Addresses (and allow all others): The MAC addresses in the list
are blocked and all other MAC addresses not included in the list are
permitted.
•Allow MAC Addresses (and block all others): Only the MAC addresses in
the list are permitted and all other MAC addresses not included in the list are
blocked.
STEP 4 In the MAC Address Filtering Rules area, specify the list of MAC addresse s. To
add a MAC address, click Add. To edit an entry, click the Edit (pencil) icon. To
delete an entry, click the Delete (x) icon. To delete multiple entries, check them and
click Delete.
For example, if you click Add, the MAC Address Filtering Rule - Add/Edit window
