5-4 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, page 5-6).
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, page 5-6).
• The Spanning Tree window, which allows you to set the Spanning Tree
Algorithm parameters (see Bridge Spanning Tree, page 5-14).
• 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, page 5-21).
• 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.
Configuring Duplex Modes
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,
Figure 5-2, will appear.
NOTE
Although this option appears on the menu accessed from the Bridge Status window, the
Duplex Mode functionality is not supported by the 9A128-01 module. Attempting to set
options in these windows will generate Set Failed errors, but will not affect the device’s
bridging functions.
