Overview The Destination MAC Filter feature prevents the AT-GS950/48PS switch
from forwarding packets to a specified device. On the Destination MAC
Filter Page of the AT-S111 Management software, enter the MAC address
of the device that you want to filter.
After the switch receives a packet, it examines the destination MAC
address of the packet. If the destination MAC address matches a
MAC address set in the filter, the software prevents the switch from
forwarding it and drops the packet.
You may want to block access to a device within your organization. For
instance, you may not want users on the Sales group switch to have
access to a server on the Accounting group switch. You can enter the
MAC address of the Accounting server as a destination MAC address filter
on the Sales group switch. When a packet destined for the Accounting
server is received by the Sales group switch, the switch drops the packet.
The Destination MAC Filter is a subset of the static MAC address. For
more information about MAC addresses, see Chapter 10, “Overview” on
page 124.
