Spanning Tree Parameters
The operation of the Spanning Tree Algorithm is governed by several
parameters. You should only attempt to set these parameters if you have

Setting the Bridge Priority to a low value will make it more likely that the
current bridge will become the root bridge. If the current bridge is located
physically near the center of your network, you may wish to decrease the Bridge
Priority from its default value of 0x8000. If the current bridge is near the edge
of your network, it is best to leave the value of the Bridge Priority at its default.
Hello Time
This is the time period between BPDUs transmitted by each bridge.
Maximum Age
Each bridge should receive regular configuration BPDUs from the direction of
the root bridge. If the Maximum Age timer expires before the bridge receives
