Understanding Optional Spanning-Tree Features - Cisco WS-CBS3032-DEL Software Configuration Manual

Configuring Optional Spanning-Tree Features
This chapter describes how to configure optional spanning-tree features on the switch. You can configure
all of these features when your switch is running the per-VLAN spanning-tree plus (PVST+). You can
configure only the noted features when your switch or switch stack is running the Multiple Spanning
Tree Protocol (MSTP) or the rapid per-VLAN spanning-tree plus (rapid-PVST+) protocol. Unless
otherwise noted, the term switch refers to a standalone switch and to a witch stack.
For information on configuring the PVST+ and rapid PVST+, see
information about the Multiple Spanning Tree Protocol (MSTP) and how to map multiple VLANs to the
same spanning-tree instance, see
For complete syntax and usage information for the commands used in this chapter, see the command
