2-6 Viewing and Managing Bridging Interfaces
¥ The Spanning Tree window shows bridge port information and protocol
parameters relating to the Spanning Tree AlgorithmÑthe method of
determining the controlling bridge when a series of bridges are placed in
parallel; see Spanning Tree, page 2-34, for details.
¥ With the Filtering Database window, you can 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 entries in these
databases to increase bridging efÞciency across your network. See Filtering
Database, page 2-41, for details.
¥ The Ethernet Special Filter Database and Token Ring Special Filter Database
windows let you conÞgure special Þltering schemes. With these schemes, 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)Ñthen 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).
¥ The I/F ConÞguration port-level menu option invokes the Interface
ConÞguration window, which allows you to select a bridging method for a
Token Ring bridging interface. This window also allows you to select one of
three transmission methods that should be used when unknown addresses are
received from end stations attached to the selected bridge port. See Using the
Novell Translation Window, page 2-97, for details.
¥ The Source Route ConÞguration option enables you to conÞgure source
routed trafÞc passing between bridge ports; see Source Route ConÞguration,
page 2-57, for details.
¥ The Bridge ConÞguration option allows you to set address and routing
information for all interfaces on a Token Ring bridging device, including the
Bridge Number and the Virtual Ring Number. It also allows you to set source
route bridging parameters at the device level. See Using the Token Ring
Bridge and Port ConÞguration Windows, page 2-65, for details.
¥ The Port ConÞguration option allows you to view the address and routing
information for an individual Token Ring bridging interface. This window
displays information that is set at the device level via the Bridge ConÞguration
window, such as the Bridge Number and the Virtual Ring Number. It also
allows you to set source route bridging parameters for that port. See Using the
Token Ring Bridge and Port ConÞguration Windows, page 2-65, for details.
¥ The Duplex Modes window lists each interface on your device and whether
or not it is operating in Full Duplex mode. The window allows you to switch
full duplex mode on and off for each interface on the device. Full Duplex
Switched Ethernet (FDSE) mode allows the interface to transmit and receive
information simultaneously, effectively doubling the available bandwidth. See
Using the Token Ring Bridge and Port ConÞguration Windows, page 2-65,
for details.
