Spanning Tree
A Spanning Tree is used to avoid redundant communication loops in networks with multiple bridging
devices. Bridges do not have an 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.
Click Configure Î Filtering Î Spanning Tree to create redundant, hot-standby networks and to
prevent network loops. If enabled, Spanning Tree prevents loops by disabling redundant links. If a
link becomes unavailable, it automatically enables a redundant link.
Complex network structures can create multiple loops within a network. The Spanning Tree
configuration blocks certain ports on MP.11 devices to control the path of communication within the
network, avoiding loops and following a Spanning Tree structure.
