Configuring Spanning Tree
To define the spanning tree settings at the switch level, perform the
following procedure:
1. From the main menu, select STP Bridge Global Settings.
The Switch Spanning Tree Settings page is displayed. See Figure 29.
Figure 29. Switch Spanning Tree Settings Page
2. From the STP Version list, select STP or RSTP.
3. In the Bridge Max Age field, enter a number for the length of time after
which stored bridge protocol data units (BPDUs) are deleted by the
bridge. All bridges in a bridged LAN use this aging time to test the age
of stored configuration messages called bridge protocol data units
(BPDUs). For example, if you use the default value of 20, all bridges
delete current configuration messages after 20 seconds. You can set
this parameter from 6 to 40 seconds.
