Bridging

Figure 5-2. The Duplex Modes Window

The main portion of the Duplex Modes window consists of a list of the interfaces available on the 9A128-01 module and their current Full Duplex state: ON indicates that Full Duplex mode has been enabled for the selected interface; OFF indicates that it has not; N/A indicates that Full Duplex is not available.

To configure the Duplex Mode for any standard Ethernet or FDDI interface:

1.In the Duplex Modes window, highlight the interface whose Duplex Mode you wish to change. Note that only one interface can be selected at a time.

2.Double-click the selected interface to toggle the Full Duplex setting from ON to OFF, or vice versa. The set will take place immediately.

Enabling and Disabling Bridging

When you disable a bridge port, you disconnect that port’s network from the bridge entirely. The port does not forward any packets, nor does it participate in Spanning Tree operations. Nodes connected to the network can still communicate with each other, but they can’t communicate with the bridge and other networks connected to the bridge. When you enable a port, the port moves from the Disabled state through the Learning and Listening states to the Forwarding or Blocking state (as determined by Spanning Tree).

To enable or disable bridging at the port interface level from the Bridge Status window:

1.Click on the desired Port button () to display the port menu.

2.Drag down to Enable to restart bridging on the selected interface, or Disable to halt bridging across the selected interface.
