Spanning Tree Protocol on a Port
The Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol
(RSTP) guard against the formation of loops in an Ethernet network
topology. A topology has a loop when two or more nodes can transmit
packets to each other over more than one data path. Packets can become
caught in repeating cycles, referred to as broadcast storms, that
needlessly consume network bandwidth and that can significantly reduce
network performance.
This chapter provides a brief description of the spanning tree protocols and
explains how to set spanning tree on a port. See the following sections:

Note
For information about how to set a spanning tree protocol for the
switch, see Chapter 12, “Spanning Tree Protocols on the Switch” on
page 143.
