Configuring Rapid PVST+
The Spanning Tree Protocol (STP) was implemented to provide a loop-free network. Rapid per VLAN
Spanning Tree (Rapid PVST+) is an updated implementation of STP that allows you to create one
spanning tree topology for each VLAN. Rapid PVST+ is the default STP mode on the switch.
This chapter includes the following sections:
•
•
•
Spanning tree is used to refer to IEEE 802.1w and IEEE 802.1s. If the text is discussing the IEEE 802.1D
Note
Spanning Tree Protocol, 802.1D is stated specifically. See
information on Multiple Spanning Tree (MST) and
complete information on STP extensions.

Information About Rapid PVST+

This section provides describes the Rapid PVST+ protocol, which is the IEEE 802.1w standard, Rapid
Spanning Tree Protocol (RSTP), implemented on a per VLAN basis. Rapid PVST+ interoperates with
the IEEE 802.1D standard, which mandates a single STP instance for all VLANs, rather than per VLAN.
(See the
Rapid PVST+ is enabled by default on the default VLAN (VLAN1) and on all newly created VLANs in
software. Rapid PVST+ interoperates with switches that run legacy IEEE 802.1D STP (see the
PVST+ Interoperation with Legacy 802.1D STP" section on page
RSTP is an improvement on the original STP standard, 802.1D, which allows faster convergence.
