Spanning TreeA Spanning Tree is used to avoid redundant communication loops in
networks with multiple bridging devices. Bridges do not have any inherent
mechanism to avoid loops, because having redundant systems is a
necessity in certain networks. However, redundant systems can cause
Broadcast Storms, multiple frame copies, and MAC address table
instability problems.
Complex network structures can create multiple loops within a network.
The Spanning Tree configuration blocks certain ports on AP devices to
control the path of communication within the network, avoiding loops and
following a spanning tree structure.
For more information on Spanning Tree protocol, please see Section 8.0
of the IEEE 802.1d standard. The Spanning Tree configuration options
are advanced settings. Avaya recommends that you leave these
parameters at their default values unless you are familiar with the
Spanning Tree protocol.
Storm ThresholdStorm Threshold is an advanced Bridge setup option that you can use to
protect the network against data overload by:
• Specifying a maximum number of frames per second as received
from a single network device (identified by its MAC address).
• Specifying an absolute maximum number of messages per port.
