6.5.2 MAC Filtering
MAC Filtering (or GUI filtering, or layer 2 address filtering) refers to a security access control
method. By this method, the 48-bit MAC address assigned to each network card is used to
determine the access to the network. You can configure the parameters and click Add at the
bottom of the page. Then, the MAC address is added to MAC List, as shown in the list.
To delete MAC address in the MAC list, click Delete Selected or Delete All Button.
Direction The direction of the filter entry can be ―Source‖ , ―Destination‖ or
―Both‖.
MAC Address When you choose the Source Direction, the MAC address in the filter
entry is the source MAC Address of the packet. On the contrary, it’s
the destination MAC address in the filter entry, when you choose the
destination Direction.
