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:

1From the Bridge menu, select [4] Destination Address Filtering to display the Destination Address Filter menu, shown in Figure 90.

2Select [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>):

3Enter 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.

4Repeat 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 Destination Filter Address menu.

■To change an address in the list, delete the incorrect address and add the correct address.

■To delete an address from the list, select [3] Delete Destination Filter Address 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.

5Select [4] Previous Menu to return to the Bridge menu.

6Select [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.
