114 CHAPTER 4: CONFIGURING PATHBUILDER S330/S310 MODULES, PORTS, AND APPLICATIONS Figure 86 Bridge Menu From the Bridge menu, you can: n Configure source protocol filtering, source address filtering, and destination address filtering. n Display the forwarding table for the bridge. n Construct a static table (a table of source/destination pairs which you do not want to be aged out of the forwarding table) for the bridge. The following subsections tell you how to perform these operations. Configuring Source Protocol Filtering Source protocol filtering allows the bridge to filter out packets with certain protocols. You can use this type of filtering to prevent certain type of protocol traffic from being bridged across the ATM network. Protocols such as IPX and Appletalk, for example, can be filtered on the sending end. This is useful in restricting your local Novell network or Appletalk data traffic from being transmitted on long distance ATM links, thereby saving bandwidth and providing security.
