It may be useful to actively specify the topology that is formed due to the Spanning Tree

Protocol and to not leave it to the random MAC addresses of the switches involved. Non-

blocking/blocking data paths can thus be inuenced and a load distribution specied. It

may also be useful to explicitly disable the Spanning Tree Protocol at ports that do not par-

ticipate in Spanning Tree so as to benet from the fast forwarding function. e Spanning

Tree Protocol must also be disabled at individual ports if two dierent network segments—

both using Spanning Tree—are to be coupled via these ports without the two tree structures

melting into a large Spanning Tree.

Specifying the Root Switch

e root switch is assigned via the assignment of an appropriate priority for the Spanning

Tree segment (see Figure 6.10). Set the highest priority (lowest value) in the Priority eld

on the STP Bridge Conguration page in WBM for the switch selected as the root switch.

Make sure that all the other network switches have a lower priority (higher value). Here the

set path costs are not evaluated.
