Configuring Destination Address Filtering
Destination address filtering prevents LAN packets with destination addresses
specified in the filter from being sent to the WAN. You can use destination address
filtering to prevent some stations from receiving data from the ATM WAN link. For
example, you can save network-traffic-sensitive stations (such as local file servers
and CAD servers) from unnecessary data coming from the WAN.
To configure destination address filtering, follow these steps:
1 From the Bridge menu, select [4] Destination Address Filtering to display the
Destination Address Filter menu, shown in Figure 90.
Figure 90 Destination Address Filter Menu
2 Select [2] Add Destination Filter Address. The Add Destination Address Filter
screen appears. This screen displays the following prompt:
Enter MAC Address (XX:XX:XX:XX:XX:XX or <CR>):
3 Enter the MAC address of the destination to which you do not want packets to be
sent across the bridge. After you make your entry, you are returned to the Source
Address Filter menu.
4 Repeat steps 2 and 3, as desired, to add more addresses to the destination filter
list.
To view the current list, select [1] List Destination Filter Address from the
n
Destination Filter Address menu.
To change an address in the list, delete the incorrect address and add the
n
correct address.
To delete an address from the list, select [3] Delete Destination Filter Address
n
from the Destination Filter Address menu and enter the number corresponding
to the address you want to delete. Then enter 2 at the confirmation prompt to
delete the selected address.
5 Select [4] Previous Menu to return to the Bridge menu.
6 Select [1] Setup to display the Bridge Setup menu, shown earlier in Figure 88. This
menu allows you to enable or disable the filters you have configured.
