Conﬁguring Duplex Modes | Cabletron Systems 9A128-01 specification

Bridging

•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.

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.

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.
