9E312/9E423 Module Bridging

•The Spanning Tree window shows bridge port information and protocol parameters relating to the Spanning Tree Algorithm (the method of determining the controlling bridge when a series of bridges are placed in parallel).

•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 9E312-12/ 9E423-24 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 Duplex Modes window lists each interface on your device and whether or not it is using Full Duplex mode. The window allows you to switch full duplex mode on and off for each interface on the device. Full Duplex Switched Ethernet (FDSE) mode allows the interface to transmit and receive information simultaneously.

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 9E312/9E423 Module. To access the Bridge Status window from the Module View window:

1.Click on the Device selection in the menu bar. A pull-down menu will appear.

2.Click on Bridge Status.... The Bridge Status window, Figure 3-1, will appear.

NOTE

Preliminary versions of 9E312 ﬁrmware identify the INB port (Port 1) as being an FDDI type port. This is incorrect, as the INB is not an FDDI bus.
