Spanning Tree Protocol
Spanning Tree Protocol is a link management protocol that provides path
redundancy while preventing undesirable loops in the network. For an Ethernet
network to function properly, only one active path can exist between two
stations.
Multiple active paths between stations cause loops in the network. If a loop
exists in the network topology, the potential exists for duplication of messages.
When loops occur, some switches see stations appear on both sides of the
switch. This condition confuses the forwarding algorithm and results in duplicate
frames being forwarded.
Enabling Spanning Tree Protocol

CONFIGURATION menu.
