This chapter describes how to configure the Spanning Tree Protocol (STP) on port-based VLANs on the
Catalyst 3560 switch. The switch can use either the per-VLAN spanning-tree plus (PVST+) protocol
based on the IEEE 802.1D standard and Cisco proprietary extensions, or the rapid per-VLAN
spanning-tree plus (rapid-PVST+) protocol based on the IEEE 802.1w standard.
For information about the Multiple Spanning Tree Protocol (MSTP) and how to map multiple VLANs
to the same spanning-tree instance, see Chapter 19, “Configuring MSTP.” For information about other
spanning-tree features such as Port Fast, UplinkFast, root guard, and so forth, see Chapter 20,
“Configuring Optional Spanning-Tree Features.”
