Spanning Tree
The Spanning Tree Protocol is a link management protocol that provides path
redundancy and prevents unwanted loops. Several active paths between stations
in a network create loops in the network. In an Ethernet network, only one active
path can exist between two stations.
To establish path redundancy, the spanning tree protocol creates a tree that spans
all switches in an extended network. The protocol puts redundant data paths into a
standby (blocked) state.
Within Spanning Tree, you can configure the following:

Ports
Spanning Tree Bridge Parameters
The Bridge option allows you to set Spanning Tree Bridge parameters.

When you create fault-tolerant networks, you must have a loop-free path between
all nodes in the network. If a loop exists in the network, hosts might receive
duplicate messages resulting in an unstable network. The Spanning Tree Protocol
(STP) calculates the best loop-free path throughout a switched network. Switches
send and receive spanning tree frames at regular intervals. The switches do not
forward these frames, but use the frames to construct a loop-free path.
