Configuring STP
This chapter describes how to configure the Spanning Tree Protocol (STP) on port-based VLANs on the
IE3000 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
spanning-tree features such as Port Fast, UplinkFast, root guard, and so forth, see
"Configuring Optional Spanning-Tree Features."
