The Bridge Status Window 3-3

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.
