Using the Configuration STP Menu<br />

(Root Bridge Only)<br />

Using the Spanning-Tree Protocol 8 - 9<br />

The STP Protocol for a root bridge is configured using the Configuration<br />

STP Menu. This menu will only appear if the Root Mo<strong>de</strong> is “On” as<br />

<strong>de</strong>scribed in Chapter 4 “Configuring the Radio Network”. To access<br />

this menu, select Configuration from the Main Menu, then select STP<br />

from the Configuration Menu.<br />

Configuration Stp Menu<br />

Option Value Description<br />

1 - Active [ off ] - Protocol enabled<br />

2 - Bridge [ menu ] - Bridge parameters<br />

3 - Port [ menu ] - Port parameters<br />

4 - Display - Protocol status<br />

5 - State [ "Forward" ] - Local ethernet <strong>port</strong> state<br />

Enabling STP Protocol (Active)<br />

The active option acts as an On/Off switch for the STP protocol. The<br />

<strong>de</strong>fault setting is “Off”, which means all root and repeater LAN <strong>port</strong>s<br />

are placed in the forwarding state. If the option is turned “On”, the root<br />

and repeater LAN <strong>port</strong>s are placed in the listening state.<br />

If you are running a small infrastructure, and there will never be any<br />

loops, leave the STP protocol “Off”. If you are unsure, change the setting<br />

to “On” as the overhead involved for bridges is small.<br />

Setting Bridge Parameters (Bridge)<br />

The bridge option allows you to set the overall parameters and timeout<br />

values for a root bridge. When the bridge option is selected, the Configure<br />

STP Bridge Menu appears.<br />
