Configuring Optional Spanning-Tree Features

This chapter describes how to configure optional spanning-tree features on the Cisco ME 3800X and
ME 3600X switch. You can configure all of these features when your switch is running per-VLAN
spanning-tree plus (PVST+). You can configure only the noted features when your switch is running the
Multiple Spanning Tree Protocol (MSTP) or the rapid per-VLAN spanning-tree plus (rapid-PVST+)
protocol. STP is enabled by default on switch ports.
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
Note For complete syntax and usage information for the commands used in this chapter, see the command
reference for this release.
