Configuring Source Address Filtering
Source address filtering allows the bridge to prevent packets containing a specific
source address from traversing the bridge. You can use source address filtering to
prevent some stations from transmitting on the ATM WAN link. This type of
filtering is useful for preventing specific stations in a common protocol group on
the Ethernet LAN from transmitting bursty and useless network data across the
bridge and onto the WAN.
To configure source address filtering:
1 From the Bridge menu, select [4] Source Address Filtering to open the Source
Address Filter menu, shown in Figure 97.
Figure 97 Source Address Filter Menu
2 Select [2] Add Source Filter Address. The Add Source 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 station from which you do not want packets to
traverse 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 source filter list.
To view the current list, select [1] List Source Filter Address from the Source
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 Source Filter Address from
the Source Filter Address menu and enter the number corresponding to the
address you want to delete. Then enter
the selected address.
5 Select [4] Previous Menu to return to the Bridge menu
6 Select [1] Setup to open the Bridge Setup menu, shown earlier in Figure 96. This
menu allows you to enable or disable the filters you have configured.
