When configuring bridging parameters, you will need to perform at least some of the 
following steps:

The bridging menu commands operate only on the currently selected group (or, for certain 
commands, VLAN). You can select a group with the 

command. For information on using 

There are several commands that allow you to configure and view basic bridging functions 
such as static MAC addresses, bridge forwarding tables, MAC information and statistics, and 
remote Trunking stations. Many of these commands are useful in diagnosing network prob-
lems, as they allow you to find specific MAC addresses and the port on which they were 
learned. For information on these commands, see Bridging Commands on page 17-8.

Spanning tree is an algorithm that helps prevent broadcast storms by blocking ports in the 
network from transmitting data. If you plan to use spanning tree, you can use the spanning 
tree commands to configure and view IEEE and IBM Spanning Tree. For information on using 
spanning tree commands, see Configuring Spanning Tree on page 17-23.

Fast Spanning Tree is an algorithm that helps provide quick recovery from link, port and 
device failures on a network, by bringing blocked secondary links into forwarding mode as 
quickly as possible. You can the Fast Spanning Tree commands in the Bridge Management 
Menu to view and enable/disable Fast Spanning Tree parameters on a selected group or 
VLAN. For information on using Fast Spanning Tree commands, see Configuring Fast Span-
ning Tree on page 17-34.
