Using the Spanning Tree Protocol 8 - 9
Using the Configuration STP Menu
(Root Bridge Only)
The STP Protocol for a root Bridge is conÞgured using the ConÞgura-
tion STP Menu. This menu will only appear if the Root Mode is ÒOnÓ as
described in Chapter 4 ÒConÞguring the Radio NetworkÓ. To access
this menu, select ConÞguration from the Main Menu, then select STP
from the ConÞguration Menu.
Enabling STP Protocol (Active)
The active option acts as an On/Off switch for the STP protocol. The
default setting is ÒOffÓ, which means all root and repeater LAN ports
are placed in the forwarding state. If the option is turned ÒOnÓ, the root
and repeater LAN ports are placed in the listening state.
If you are running a small infrastructure, and there will never be any
loops, leave the STP protocol ÒOffÓ. If you are unsure, change the set-
ting to ÒOnÓ as the overhead involved for Bridges is small.
Setting Bridge Parameters (Bridge)
The bridge option allows you to set the overall parameters and timeout
values for a root Bridge. When the bridge option is selected, the ConÞg-
ure STP Bridge Menu appears.
