Bridging

•With the Filtering Database window, you can see the contents of the Static and Learned databases — the two address databases which construct the IEEE 802.1d Source Address Table. The switch uses the contents of these databases to make its packet filtering and forwarding decisions when using 802.1d bridging. You can configure entries in these databases to increase bridging efficiency across your network.

•The Port Source Addressing window displays the contents of the 9H42x-xx switch’s 802.1d Bridge Filtering Database with respect to a selected interface. This will display the source MAC addresses that have been detected by the interface as it forwards data across the network. The window also lets you set the ageing timer that controls how long an inactive MAC address will continue to be stored in the Source Address Database before being aged out.

•The bridge-level Duplex Modes and port-level Configuration options allow you to set Duplex Mode operation for standard Ethernet interfaces; the port-level Configuration option for Fast Ethernet interfaces also allows you to configure parameters related to auto-negotiation. The Duplex Modes window is described beginning on page 5-25; the port configuration windows are described in Chapter 2.

The following sections detail how to use each of the bridge management windows.

The Bridge Status Window

The Bridge Status window provides you with basic information about the current status of bridging across your device. Color-coding of each port display allows you to quickly ascertain the status of each interface. The Bridge Status window also lets you access further windows to control bridging at your 9H42x-xx module.

To access the Bridge Status window from the Module View:

1.Click on Device to display the Device menu.

2.Click to select Bridge Status.... The Bridge Status window, Figure 5-1, will appear.
