Using Transparent Bridge Services
117351-A Rev. A 1-15
Filtering Frames
You use filters mainly for security reasons. They enable the bridge to relay or drop
a particular frame based on user-selectable fields within each of these four
encapsulation methods supported by the bridge:
• Ethernet
• IEEE 802.2 LLC
• IEEE 802.2 LLC with SNAP header
• Novell proprietary
See Configuring Traffic Filters and Protocol Prioritization for details about filters
and how to configure them for the bridge.
Enabling Bridge Service
This section describes how to enable bridge service and, optionally, spanning tree
on an interface. It assumes you have read Configuring and Managing Routers with
Site Manager and that you have
1. Opened a configuration file.
2. Specified router hardware if this is a local-mode configuration file.
3. Selected the link- or net-module connector on which you are enabling
bridge service, or configured a WAN circuit if this connector requires
one.
Enabling Bridge Service on an Interface
To enable bridge service without spanning tree, select Bridge from the Select
Protocols menu and click on OK. The Select Protocols menu appears after you
either select a link- or net-module connector, or finish configuring a WAN circuit.
When you enable bridge service without spanning tree, you need not specify any
configuration information, because Configuration Manager supplies default values
for the bridge parameters. The window for the next enabled protocol appears or, if
only bridge is enabled on this circuit, the Bay Networks Configuration Manager
window appears. To edit the default values for the bridge parameters, see Editing
Bridge Parameterson page 1-18 for instructions.
