Configuring Duplex Modes

•

A Module Type window that contains a description of the 9A128-01 module, 
see Viewing Hardware Types in Chapter 2 for more information.

•

A Bridge Performance Graph that displays statistics for traffic across the entire 
bridge (see Bridge Statistics, 

).

A Performance Graph window is also available for each individual interface, 
by clicking on a port index button to display the port level management 
options (see Bridge Statistics, 

•

The Spanning Tree window, which allows you to set the Spanning Tree 
Algorithm parameters (see Bridge Spanning Tree, 

•

The Filtering Database window, which lets you configure the bridge’s 
acquired and permanent filtering databases to filter or forward traffic across 
the selected module (see Filtering Database, 

•

The Duplex Modes window, which allows you to configure duplex mode (on 
or off) for standard Ethernet and FDDI interfaces; see Configuring Duplex 
Modes

, below, for details.

Enabling Full Duplex mode on an interface allows the interface to receive and 
transmit packets at the same time, effectively doubling the available bandwidth 
(and, therefore, the wire speed) on the selected interface. Interfaces which are not 
set to Full Duplex mode must receive and transmit separately, waiting for one 
activity to be completed before the other is begun.

To access the Duplex Modes window:

1.

Click on 

 to display the main Bridge menu;

2.

Drag down to Duplex Mode(s)..., and release. The Duplex Modes Window, 

, will appear.
