Bridging
2-10 The Bridge Status Window
¥ The Spanning Tree window allows you to set the Spanning Tree Algorithm
parameters for bridging on your device; see Spanning Tree, page 2-34, for
details.
¥ The SmartTrunk option invokes the SmartTrunk ConÞguration and Status
window, which enables you to group interfaces logically to achieve greater
bandwidth between devices, if both devices support the SmartTrunk feature.
There is no limit to the number of ports that can be included in a single
Òtrunk,Ó nor is there a limit to the number of trunked ÒinstancesÓ that can be
supported. See ConÞguring SmartTrunking, page 2-85, for details.
¥ The Filtering Database window lets you see the contents of the Static and
Learned databasesÑthe two address databases which construct the IEEE 802.1
Source Address Table. The bridge uses the contents of these databases to make
its packet Þltering and forwarding decisions. You can conÞgure the bridgeÕs
acquired and permanent Þltering databases to Þlter or forward trafÞc across
the device. See Filtering Database, page 2-41, for details.
¥ The Ethernet Special Filter Database window lets you conÞgure a special
Þltering scheme at your bridge. With this scheme, you can enter Þlter
parameters for a frame based on the contents of its source or destination
address Þeld, type Þeld, or data Þeld (with offset); you can then specify the
bridging action to take place at each port when a frame matching your
speciÞcations is encountered. See Special Filter Databases, page 2-47, for
details.
¥ The Token Ring Special Filter Database window enables you to deÞne
complex Þlters for transparently-bridged Token Ring frames based upon
receive port, source or destination MAC address, Token Ring data type, or data
Þeld information (up to 64 bytes); see Special Filter Databases, page 2-47, for
details.
¥ The Token Ring Bridge Mode window lets you select which type of bridging
will be used by the Token Ring bridging deviceÑTransparent, Source Routing,
or Source Route Transparent; see Token Ring Bridge Mode, page 2-89, for
details.
¥ The Bridge Translation window allows you to control the necessary
translation of frames that must occur for Token Ring frames to be bridged to
Ethernet. This window offers Auto and Dual modes for translation and
includes the IBM and SNAP Translation tables. See Setting Bridge
Translation, page 2-91, for details.
¥ The Novell Translation window enables you to conÞgure each module port
for translation of Novell packets that are received and transmitted across a
Token Ring bridge; see Using the Novell Translation Window, page 2-97, for
details.
¥ The Duplex Modes window allows you to conÞgure duplex mode (on or off)
for supporting interfaces on the device; see Using the Token Ring Bridge and
Port ConÞguration Windows, page 2-65, for details.
