Configuring Ethernet Modules 155
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.
n
View and clear bridge statistics.
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.
To configure source protocol filtering, follow these steps:
1 From the Bridge menu, select [2] Source Protocol Filtering to display the Source
Protocol Filter menu, shown in Figure 119.
Figure 119 Source Protocol Filter Menu
The current statuses of the source protocol filters are listed at the top of the menu.
Yes indicates that packets with that protocol will be rejected. No indicates that
packets with that protocol will be transmitted across the bridge.
2 Change the filter settings as desired by entering the number corresponding to the
filter you want to set and responding to the prompt that appears at the bottom of
the screen. The list at the top of the menu is updated to reflect your change.
